1. Introduction

This document and the attached exhibits have been prepared by Evans Associates, Consultants inCommunications Technology, representing the consulting team of Evans Associates and The AegisGroup. This document is provided to the Mississippi Library Commission (MLC) in partialfulfillment of our contract to provide telecommunications consulting services to MLC.

In late 1994, the MLC undertook a telecommunications feasibility study with the State Board forCommunity & Junior Colleges (SBCJC) and the Mississippi Association for Community & JuniorColleges (MACJC). This study concluded that "a significant need and justification (exists) forexpanded local and statewide telecommunications initiatives in the State of Mississippi". Based onthis need, a combined MLC/college video/data network was designed, based on expansion of theexisting Community College Network (CCN). This network was to feature dial-in access by thepublic libraries, with community college campuses serving as dial-in locations. The dial-in networkwas seen as a "Phase I" solution which could satisfy the needs of the libraries until the infrastructurefor a permanent, dedicated network based on emerging Frame Relay technology could be built bythe providers. As part of the design, a network implementation budget of $29.9 million wasdetailed; of this amount, $1.975 million was budgeted specifically for creating MLC's portion of thedata and video network. Based on this budget, the Mississippi legislature proposed and enacted abill which authorizes the issuance of state bonds to procure the funds for building the network.

Since the completion of the report, two factors have fundamentally changed the direction of MLC'sefforts. First and foremost, Mississippi's telecommunications vendors (primarily Bell South) haveimplemented statewide Frame Relay service much more quickly than they had originally indicated,and have offered extremely favorable pricing to state government agencies. Secondly, MLC haselected to delay participation in the video portion of the network until new MLC facilities arecompleted and occupied, probably in 1998. As a result of these factors, it is now possible for MLCto deploy the "Phase II" data network directly, without creating the "Phase I" network first, andwithout requiring additional funding. The "Phase II" data network, based on Frame Relaytechnology, will provide more functionality at a higher speed to the public libraries than the Phase Idial-in network could have offered.

Towards these ends, the following document represents a detailed design for the data portion of theMLC public library network. Although this network is being designed and installed using the fundsavailable from the bonds, it is important to consider that the ongoing cost of the network will needto be borne by the libraries. Therefore, careful consideration has been given to minimize theseongoing costs.

2. Current Environment

The Mission Statement of the Library Commission reads as follows:

Mississippi Library CommissionData Network Specifications

The Mississippi Library Commission assumes a leadership role to fulfill the information needs of theresidents of Mississippi by advocating the development of efficient, effective public library systems and byencouraging cooperation among all types of libraries.

The Commission will continue to take a proactive position to improve the quality of library services byutilizing effective management practices including planning, education and communication. Consistent withstate and federal mandates, the Commission commits available resources to provide appropriate servicesby fairly and consistently applying policies that assure accountability to funding authorities, serviceproviders, supporters and users.

The Mississippi Library Commission (MLC), established in 1926, is an independent state agencycreated to serve the citizens of the state through their public libraries as well as members of thelegislature, state officials, state agencies and state employees directly. MLC also serves stateresidents with visual or physical handicaps which prevent the reading of conventional print.

One focus of the Mississippi Library Commission is public libraries with cooperative activitieswith school, academic, and special libraries. There are 45 public library systems with over half(1.2 million) of Mississippi's citizens registered users.

MLC is the primary resource library for Mississippi public libraries. To fulfill this role, theagency has a general collection of 200,000 books, subscriptions to 500 periodicals, 50,000 stateand federal documents, over 100 CD-ROMs, and a collection of 5,000 audiovisual titles.

The Commission's assistance to libraries takes many forms: consulting, grants, reference, summerreading club, programming, continuing education, and other services.

The MLC currently uses an IBM RS/6000 server running the Dynix library automation package.This package catalogs and provides access to the MLC's own holdings of library materials. TheRS/6000 has dial-in capability using the Dynix "DialPAC" feature. MLC also has two local areanetworks (LANs) in their building; each runs Novell 4.1 network software and each is connectedvia Ethernet to the RS/6000. TCP/IP functionality on the Novell LANs is provided by Novell'sLAN Workplace product.

3. Desired Functionality

The MLC requires that the data network being created offer the following functionality to MLCemployees and to the state's public libraries:

Full Internet access, including access to the World Wide Web and Internet e-mail.

On-line in-state access to the Dynix system (and, by extension, MLC's holdings) andto a proposed MLC CD tower by public libraries. Access from Internet to the CDtower is not desired.

Mississippi Library CommissionData Network Specifications

Capability for access to such services as OCLC First Search program.

Capability for on-line access to the Mississippi Union Catalog (MUC), currentlymaintained on CD by MLC and updated annually.

The MLC's holdings (and the MUC as well) will be made available for browse andsearch to the World Wide Web community.

Capability for users to fill out and submit on-line Inter-Library Loan (ILL) requests.

A bulletin board (for event schedules, job postings, etc) for use by Mississippilibrarians.

Capability for on-line access to other state holdings, such as the universities' librarycatalogs (should the universities choose to make such holdings available).

Capability to host multiple sets of World Wide Web pages/sites.

Capability for users to directly download catalog information from MLC or theMUC into ILL requests or their own computerized catalog.

This network will be created by establishing the network server(s) at the MLC's offices in Jackson,and then making those services available to public libraries throughout the state. For Internetaccess, libraries will pass their traffic to the state's designated Internet Service Provider (ISP)through the MLC connection. The Internet portion of this design has been decided on by the Stateand MLC. The specific topology of the "downstream" network (i.e. between MLC and the publiclibraries) will be detailed inSection 8. However, it is important to note here that the MLC will beproviding PC computers to the public libraries for use in accessing the network; these PCs will bepre-configured with the necessary hardware and software. Therefore, the hardware and softwareused at the MLC central site must be chosen and implemented with the thought that compatiblesoftware will be going to the public libraries, most of which are staffed by people of limitedcomputer expertise.

It is understood that realizing all these goals will not be the complete responsibility of any onevendor. The creation of this network will require the coordinated contributions of a number ofhardware, software, agency, and service providers. The recommendations included in thisdocument are consistent with the objective of open systems development.

4. Network Overview/Cost Summary

This section will provide an overview of the topology and costs of the proposed network.Subsequent sections of this document will provide the additional detail and cost breakdownsnecessary to implement the network.

As explained in Section 1, this network will be based on Frame Relay technology. Figure 1 belowshows the locations of each Bell South "cloud" hub, and the approximate number of public librariesreachable by that cloud; additional detail on the MLC central site is given in Figure 7:

Figure 1: Basic Network Architecture

Each headquarters (HQ) library acts as a hub for its own branches that use dedicated (leased) linesfor network access (smaller libraries will use dial-up access, as explained in Section 8). PrivateVirtual Circuits (PVCs) will be set up from the HQ to each branch through the local cloud using 56kbs lines. An additional PVC will connect each branch with the state's Internet Service Provider(ISP). The HQs are connected to the cloud through a 56 kbs line or a T-1 line, depending on trafficestimates. A router will be placed at each HQ and dedicated line access branch.

At the MLC, several new servers will be added to the MLC LAN in order to service the requestswhich come in via the network from the Internet and from state public libraries. The specificationfor all of this equipment is provided in this document. These new servers include:

A Web server to process the World Wide Web requests from public libraries and the Internet;

An FTP/Mail server to process file transfers and electronic mail;

A Spectrum computer (not shown in Figure 1) for MLC Help Desk network monitoring;

A server to drive the proposed CD-ROM tower;

A database server to allow for dynamic web-page access to other MLC data (to be added to thenetwork in a later phase; see section 12).

These cost projections cover all known cost areas involved in the creation and operation of thisnetwork with the exception of the following:

1. Firewall costs (see Section 12);2. Costs to attach library systems' LANs to network (see Section 9);3. Internet access charges (not known at this time);4. CD-ROM tower/server (to be financed outside of this budget)5. Class C license registration fees, if any (see Section 7)

5. Hardware Requirements

Web/Database Server Discussion

The sizing and deployment of server hardware (and software) is dependent on the strategy chosento provide access to information. Two strategies are available:

i) Exclusively via Web Server: Under this strategy all information that needs to bemade accessible has to be created and organized into Web pages with appropriatelinks for navigational purposes. Web pages on the server are static and anychange in the content would require updating, reformatting, and refreshing of theWeb server documents. This process can be time consuming and is dependent onthe type and the amount of information on the Web Server and the frequency ofchanges made to the content. See Figure 3.

Figure 3: Web Server Onlyii) Use of Web and Database Server: This approach allows creating and storage of

static as well as dynamic Web pages. Depending on the information typerequested, HTML pages can be retrieved from the Web server or created "on thefly" from data retrieved in real time from a database on the Database server (seeFigure 4). Additionally, this strategy allows for the use of form capabilityavailable in browsers. Forms capability could:

* Allow MLC to provide search and retrieval capability where searchparameters can be entered by users with results retrieved from the databasesent as Web pages.

* Allow MLC to create data entry forms that libraries can use to fill outrequests (e.g. inter-library loan, substitute for fax, etc.) and transmit.Information from the forms can be stored in the database and furtherautomated processing can be performed with the ability to provide varioustypes of reporting.

Figure 4: Web/Database Servers

A Web server exclusive strategy would suggest a hardware configuration with large storagecapacity on the Web server, whereas using a combination Web and Database server strategy, thestorage capacity is split between the Web server and the Database server.

The Web/Database combination strategy provides significant flexibility and is therefore highlyrecommended. However, it is felt that the initial implementation of the network can be done withonly the Web server; the Database server should be added later in the implementation cycle (seeSection 12).

Detailed Hardware Specifications

The following specifications are provided for the needed network hardware. Refer to Figure 1,"Basic Network Architecture".

An Internet World Wide Web server (which also includes DNS service): single-processor Pentium PC, at least 1.5 GB of hard disk space, 32 MB memory, CD-ROM drive, and DAT tape unit.

Mississippi Library CommissionData Network Specifications

A computer which functions as the MLC's database network server will be required.This computer will be the unit which will house and allow access to the databasesnot already present on the Dynix system, and should be equipped with:

A Pentium processor, with a clock speed of at least 166 MHz. The computershould have the capability for the addition of multiple processors in thefuture, to a total of at least four. Sun or other processors could be substitutedfor the Pentium, with no loss in functionality or compatibility. However, itis felt that Pentium/Windows NT platforms are lower in price, providegreater choice of third-party software, and are generally easier to support.Additionally, there is a greater availability of Pentium/NT support skills inthe workforce. If these issues are adequately addressed by MLC, then otherplatforms for both the database server and the Web server may beconsidered.

A minimum of 64 MB of memory for each processor.

A media retrieval storage device which features multiple, mirrored plug-indisk drives of at least 2 GB each.

A DAT-format tape backup unit of at least 8 GB capacity.

An FTP/electronic mail server: same specifications as the Web server above.

Note: Separate servers for databases, Web activities, and FTP/mail have beenrecommended as outlined above. Although it is technically possible to run all theseapplications on a single server, lack of specific performance and traffic volume datafor the projected network makes this inadvisable. Installing separate servers allowsmaximum flexibility and room for expansion, and prevents a potential bottleneck inthe network.

CD ROM Server/Tower which holds at least 100 discs. Must support TCP/IPprotocol and allow access through a Web browser. Also, the towerhardware/software must allow access control to the level of individual discs by userID; this is needed in order to address CD licensing concerns. MLC has indicatedthat the CD ROM Tower will be purchased with funds outside of the budget of thisproject. Accordingly, the cost for this unit is not reflected in this document's projectbudget. More detailed specifications for this unit have been previously provided toMLC, and are given in Attachment 5 of this report.

Capacity Estimates: it is estimated that the database and Web servers as describedabove will be able to handle 30 to 40 simultaneous accesses. Note that this is notthe same as a capacity of 30 to 40 simultaneous users; Web access, for example,involves bursts of heavy information download followed by seconds or minutes ofthe user reading what is on their screen. Specifying 30 to 40 simultaneous accessesmeans that this number of users actually request information from the server at thesame moment. Thus the capacity of the network in terms of simultaneous users willbe significantly higher; an actual value would depend greatly on what activities theusers were requesting. The traffic on the e-mail, router management, and dial-inrouters is deemed to be sufficient to handle all of the devices connected on thenetwork.

6. Software Requirements

The following network and system software is recommended, and is based on the use of theWindows NT platforms recommended above. If other platforms (such as Sun or Silicon Graphics)are chosen, then similar software will need to be substituted:

Windows NT Server software for the server computers. This software comesbundled with TCP/IP and DNS support. NT Server has been specifically designedfor server and network applications, and is ideally suited for the tasks which MLCdesires to implement.

Database software for the database server. Recommended: SQL Server softwarewith which a Web server can interact, such as Microsoft SQL Server or Oracle.

Web server software, such as is available from Netscape, Spry, O'Reilly, ProcessSoftware, or Frontier Technologies. Microsoft announced in December, 1995 thatWindows NT Server will include Web server capability atno additional cost.

Software to manage the router environment will be required. As noted above, MLChas evaluated several packages and has selected the Spectrum package fromCabletron. This package has been selected by MLC partly because it performsmultiple functions using a single database; in addition to router management, thepackage will allow MLC to track hardware inventory and provide better "help desk"functions. The consulting team supports this selection.

MLC will require some custom software development to interface the Web serverwith the database server; in other words, this effort will be required to allow users tosearch for and display information in the databases, probably using Web forms andqueries. This work can be done by a third-party software developer. Linking of theWeb server to the database server may, however, also be done using connectivitysoftware provided by many third party vendors. Microsoft has announced that itsInternet Information Server (Web Server) will integrate with the Microsoft SQLserver (database server) at no additional cost. Forms development is done usinginternal resources or can be contracted to third parties.. The level of effort andresource required is a function of the complexity of the application beingdeveloped.

Internet browser and mail software for the client (user) PCs. The recent releases ofWeb browser software (such as Netscape 3.0) also support electronic mail. Othersoftware provided by the ISP can also be added to access newsgroups. No cost isbudgeted for the browser, as most (including Netscape 3.0) are free to public

libraries. If MLC should desire to provide "screening" software to inhibit certainInternet functions, this should also be discussed with the ISP.

Software to interface the Dynix system to an Internet interface. This software isavailable from Dynix and will reside on the Dynix server. If desired, restrictingaccess to this function to the state's public libraries connected to the network (i.e.keeping general Internet users from this function) can be accomplished through therouter and/or restrictions programmed into the Web server software.

Prices for the above software are given in Figure 5.

If MLC decides to implement a bulletin board function, this can be accomplishedthrough software readily available from vendors/packages such as Galacticom andMustang BBS. This software should reside on the mail server.

7. Network Requirements At MLC

A Cisco 4500 router with 4 serial and 4 ethernet outlets (to connect to MLC's otherservers).

Three T-1 connections to the Jackson Frame Relay cloud to support traffic to/fromthe libraries and to/from the Internet.

Each T-1 line will require a CSU/DSU (modem) unit at MLC.

Prices and exact specifications for all network routers and CSU/DSUs are given inFigure 6 below:

A blueprint form MLC's hardware and network connections is given in Figure 7.

Figure 7: MLC Site Installation BlueprintIP Addressing

In order to properly route and manage the network, Internet Protocol (IP) addresses are neededby:

Local Area Networks (LANs),Devices on the LANs,Wide area network (WAN) point to point serial links provided by the Bell South frame relaynetwork, andNetwork devices (e.g. CSU/DSUs).

Two IP addressing strategies public IP addressing and private IP addressing are describedbelow, along with advantages and disadvantages of each. Specific, detailed IP addresses forMLC member libraries are given at the end of this document in Figure 16 (device IP addresses)and Figure 17 (WAN IP addresses) for both schemes.

Public Addressing: This method uses the Internet-provided Class C addresses. Under thisscenario the first 3 bytes of a 4 byte IP address are pre-allocated to each district by the assignor,with the definition of the fourth byte under local control (but specified in this document). Underthis addressing strategy MLC would acquire one Class C address for each HQ. This address canbe segmented and shared between the HQ and its branches. This would be done by dividing thefourth byte of the HQ's Class C (C.C.C.X) address as follows:

X = xxxx yyyy where xxxx represents subnets and yyyy represents devices on a subnet.

This allows for 16 subnets and 14 devices per subnet (Device 0 and 15 are special addresses andnot available). Assigning the subnet number to building numbers (HQ is building number 1,branch libraries are assigned building Ws 2, 3, ), 15 buildings per Class C address could besupported (subnet 0 is not assigned). If there are more than 15 buildings per HQ, then a secondClass address would have to be assigned to the HQ.

Of the 14 available devices per subnet, device id 1 is assigned to the Ethernet port on the routerand device id 2 is reserved for a LAN server. Device ids 3 through 14 are available for PCs ,

network printers, and additional servers that need IP address. Multiple subnets would have to beassigned to a building if there are more than 14 devices that need IP addresses.

The following formula can be used to assign the address ranges for the LANs and devices at thebranch libraries and the HQs. As mentioned earlier the first address is used for the Ethernet Portand the second address is reserved for a LAN server.

X = (Subnet # *16+1) to (Subnet#*16+14) where Subnet # is the same as the Building #

Subnet Mask = 255.255.255.240

Using the formula, Figure 16 lists address assignments using Class C addressing strategy. Pleasenote that C# represents the first 3 bytes of the Class C address and is pre-assigned.

In addition to addressing the LANs and the devices on the LAN, the wide area links that connectthe HQ locations to the branch libraries and the MLC need addresses for routing purposes. Thewide area links are represented by the permanent virtual circuits (PVCs) provided via the BellSouth frame relay network. Using the public addressing approach, another Class C address(CW.CW.CW.Y) for each HQ has to be assigned and subnetted as follows:

Y = xxxxx yyy where xxxx represents subnets and yyy allows for 6 devices per subnet.

Subnet Mask = 255.255.255.248

Mississippi Library CommissionData Network Specifications

Each subnet would represent the serial link connection (2 device id one per each end) anddevice ids 3 and 4 can be allocated to the CSU/DSUs that connect to the serial ports. The ClassC address can be more efficiently used if SNMP CSU/DSUs are not used. In this case, six bitscan be allocated for subnetting instead of five bits allowing support of 64 serial connections perClass C address and 2 device ids per subnet.

Using five bit subnetting the following rules may be used to assign the address for serial linksand the CSU/DSUs:

1. Subnet 1 assigned for connection to the MLC2. Subnets 2, 3.... assigned for serial links to the branch library using building numbers.3. Device id 1 assigned to distant end of the serial link as viewed from the HQ site.4. Device id 2 assigned to the serial link at the HQ end.5. Device ids 3 and 4 assigned to CSU/DSUs if needed.

Using the above rules, addresses can be assigned for the serial connections by using thefollowing formula:

1. Serial sub-interface from branch library to HQ: Y = (Bldg#*8)+12. Serial sub-interface from HQ to branch library: Y = (Bldg#*8)+23. CSU/DSU at branch library end: Y = (Bldg # *8) +34. CSU/DSU at HQ end: Y = (Bldg#*8)+4

(Note: This address needs to be assigned only once.)5. Serial sub-interface from MLC to HQs: Y = (1*8)+1 = 96. Serial sub-interface from HQs to MLC: Y = (1*8)+2 = 107. CSU/DSUs at MLC: Y = (1*8)+3 = 11

(Note: This address needs to be assigned only once for each DSU/CSU.)

Using the above formula, Figure 17 lists address assignments using Class C addressing strategy.Please note that CW# represents the first 3 bytes of the Class C address used for WAN seriallinks for each HQs.

Private Addressing: Using this strategy, a private Class A address structure unique for MLC canbe developed. The first byte of the 4 byte IP address is assigned a private network address of 10.The remaining three bytes are then available for allocation as deemed fit. The three bytesavailable can be allocated as follows:

10.S.B.X where 10 is the private network number,S is the library system number plus 99,B is the building #,X ranges from 1 to 254 as device ids with device ids 1 & 2 reserved

for the Ethernet port and the LAN server.

Subnet Mask = 255.255.255.0

Under this scenario 155 library systems can be supported (S ranges from 100 254), 255buildings or LANs can be supported per library system (B ranges from 1 to 255), and 254devices can be supported per building or LAN (X ranges from 1 to 254). Figure 16 lists theaddress assignments using the above private addressing strategy.

Wide area links can be addressed by using an address of 99 for the second byte. The third bytecan be uniquely assigned to each library system. The fourth byte can be subnetted as was done inthe public addressing approach. The following is an example:

10.99.S.X where S is the system number,X is calculated as (Bldg#*8 )+1 for serial link at branch end ,

(Bldg#*8)+2 for serial link at HQ end, 9 for the serial link end atMLC, and 10 for the serial link at the HQ end for MLC connection.

Figure 17 lists the WAN link addresses using the above formula for private addressing.

Selecting Between Public and Private Addressing: MLC could choose to implement either ofthe addressing schemes or a combination of both. Selecting one does not preclude the use of theother at a later time. The choice is dependent on address availability, connectivity needs,network size, performance and security needs, and availability of support staff.

Public addressing requires acquiring Class C address. This can be accomplished by requesting itfrom the ISP or InterNIC and providing appropriate documentation. Use of public addressrequires no translation when communication takes place outside the library environment.

Given the mission of libraries, it is possible that HQs may want to connect to Internet viamultiple means (e.g. Universities, other Library Consortiums, School Districts, etc.) in additionto using the MLC connection. Use of public addresses makes it easy to do so without requiringtranslation at the HQ or at the other end of the alternate connection or requiring that a PC havemultiple IP addresses to directly access the Internet via these multiple methods. Access flexibilityis retained with Class C addressing.

Administration and management of public addressing scheme is somewhat easier than using aprivate scheme. It does not require support for address translation. Newly hired staff are likely tobe familiar with public addressing rather than private addressing.

There are benefits with private addressing. It provides a larger address space and more flexibilityin address assignment. It avoids the need to acquire addresses from a third party.

Mississippi Library CommissionData Network Specifications

Private addressing requires a central point for translation from private to public addresses andback when traffic moves between Internet and the library network. This could create a bottleneckand potential for performance problems. Translation of addresses can be managed and supportedby the MLC staff or by the ISP. It is not entirely clear whether the ISP provides this service. Inthe event they do, there is likely to be an additional charge for the service. Some risk exists if theState changes the current ISP and the new ISP does not provide translation services. If the currentISP does not provide translation services then the MLC staff will need to manage both privateaddressing scheme and the tables and configuration data needed for translation.

It is perceived that private addressing provides some measure of security since addresses areunique and proprietary (not easily available). While private addresses are difficult to access , thetranslation service does not guarantee security if the private address is known externally andaccess to translation process is possible. Additional firewall functions would need to be added toassure a higher level of security. Similar firewall functions can also be added when using publicaddressing .

While there is no dominant reason (e.g. State standard) to select one or the other addressingscheme, it is recommended that MLC consider using public addresses. The recommendation ismade because of its ease of administration, no requirement for centralized address translation andattendant performance issues , and access flexibility. Class C addresses can be acquired withappropriate documentation . This report provides the information needed to apply for theaddresses.

Router Configuration(s): The routers at branch libraries, headquarters, and the MLC wouldhave to be configured appropriately based on the addressing scheme selected by the MLC. Asample configuration is included at the end of this document as Figure 18, and uses the publicaddressing scheme. The configuration can easily be changed to accommodate the privateaddressing structure.

The sample configuration uses static routing, given there is single route between the libraries andthe HQs and MLC. No bandwidth is used for routing update overhead.

8. Network Topology Options

The consulting team identified three options for connecting the public library endpoints with theMLC in Jackson. These options were evaluated with ITS in order to maximize efficiency andworkability while minimizing costs. All of these options assume the network will be built withinthe framework of the Bell South Frame Relay environment currently being installed in Mississippi(see Figure 1).

Given the overall telecommunications environment in Mississippi, it is not recommended that MLCpursue vendors other than Bell South. The committed relationship between Bell South' and the

Mississippi Library CommissionData Network Specifications

State combined with the very favorable pricing for lines received from Bell South is the basis forthis recommendation.

The networking options are explained below, along with features/comments; each is pictured inAttachment 3:

Option 1: Headquarters Location As Switching Hub

In this option, each headquarters (HQ) library acts as a hub for its own branches. Private VirtualCircuits (PVCs) go from the HQ to each branch through the local cloud using 56 kbs lines; the HQare connected to the cloud through a 56 kbs line or a T-1 line, depending on traffic estimates. Thisoption requires that a router be placed at each HQ and branch. Comments on this option:

Each library system is independent; problems at one HQ location should not impactothers

Requires one PVC connection from each HQ to MLC, at a slightly higher cost ($2per month per PVC)

Some HQ locations may require bigger router and higher bandwidth access link tothe Frame Relay, at higher costs

Option 2: Single Switching Hub Per Cloud

In this option, each branch and HQ library is connected via a PVC to a single hub point for each ofthe Bell South clouds. This requires a larger router at the cloud sites. Comments on this option:

Requires fewer PVC connections from each cloud to MLC

Requires one large router per Frame Relay cloud instead of more smaller ones resultin some cost savings

Support can be centralized per cloud

Failure at switching hub impacts all libraries connected to that cloud

Provides better utilization of access link; all locations use 56 kbs access andswitching hubs use T-1 access

Traffic between HQ and its own branches has to flow through switching hubs

Mississippi Library CommissionData Network Specifications

Option 3: Centralized Switching In Jackson

In this option, each branch and HQ library is connected via a PVC which travels all the way toJackson, where all switching is done.

A single point of failure (MLC) exists for all locations

MLC is a potential performance bottleneck; traffic from a library must go to MLCbefore reaching any destination, including its own HQ

Routers at branches and HQs are the same (for easier support)

All locations access the network via 56 kbs circuits, resulting in lower network costs

Support for complexity is centralized at MLC

A detailed analysis was undertaken which detailed the equipment necessary for each option (seeAttachment 4). This analysis showed that the difference in cost among the three options isrelatively small. Given this fact, the consulting team has selected Option 1 as the recommendedtopology for the network. All of the costs presented in this document assume a network createdper this option.

Figure 14, "Frame Relay Network Cost Worksheet" details the specific configuration of thisnetwork. Basically, each branch assigned a dedicated line is connected to its HQ through a 56 kbsFrame Relay connection. Branches assigned a dial-in line are discussed below. Branches served bya different cloud than that which serves the HQ are routed to their local cloud. Nine HQs withmore than 8 branches are assigned two 56 kbs lines to their cloud instead of one. Inter-cloud linksranging from one 56 kbs line to a full T-1 are proposed, depending on anticipated traffic. A moredetailed explanation of this spreadsheet is given in Section 16.

Dialup Versus Dedicated

In evaluating dial-up scenarios, several alternatives were examined:

Having branches dial their HQs for network access;

Having all branches dial MLC in Jackson through state 800-line service;

Having all branches dial MLC in Jackson through standard state business line rates.

Mississippi Library CommissionData Network Specifications

Having all branches dial directly into their local Frame Relay cloud.

Among the first three options, having all dial-up lines go to Jackson is recommended because the costdifference between this option and the others is only a few pennies per minute, and support for dial-inusers (and equipment) would be much easier at MLC than distributed out among the HQs. It is notadvisable to have HQs be responsible for supporting dial-in lines to their location due to possiblepersonnel shortages and/or lack of telecommunications networking experience at the HQ locations.

An extensive analysis of the costs to create and operate a "dial into MLC" environment usingstandard state business-line rates was conducted. Branch libraries with anticipated low usage wereidentified, primarily by their being open less than 20 hours per week. Fifty-one such libraries werefound. Another fifteen sites were specified for dialup access because they are served by localtelephone companies (i.e. not by Bell South) and their dedicated connections would be veryexpensive compared to Bell South sites' . The cost analysis shows that MLC would actually savevery little money using this topology; in fact, the monthly cost of a dialup line would be more thanthe cost of a dedicated 56 kbs line if usage exceeded 30 hours per month.

Another factor in deciding dial-up use is that many of the local voice-grade lines in Mississippi willnot support 28.8 kbs operation. This means that users dialing on such lines will see their modemsdrop to 14.4 kbs connections. This speed is considered to slow for effective network operation.

Having branches dial directly into their local Frame Relay cloud is deemed to be the only viablelong term dial-up environment worthy of consideration. However, this service is not yet offered inMississippi, although Bell South does offer the service in other states and anticipates making thisservice available in the hear future. This situation will require close monitoring by MLC. A finaldecision on whether to have some branches use dial-up technology (by dialing directly into thecloud) can be re-evaluated in 1996, as the recommended timeline shows that the branches are not tobe connected until 1997.

Apart from all the above practical considerations is the fact that branches will be required to paytheir own recurring (i.e. monthly) telecommunications charges, and many branches cannot afford thecost of a dedicated line. For these branches, the choice is limited dial-up access or no access atall. The following two figures show the relationships between hours of use and cost for bothdedicated line access (using the lowest Bell south figure of $127 per month) and dial-up use(assuming dialing into MLC using state business rates). These charts show that the "cross-over

'The nineteen sites were assigned dial-up install/monthly charges at the same rate as the BellSouth sites. However, it is likely that their actual dial-up charges (including the $.07 per minuteusage rate) would also be substantially higher than Bell South's state rates. In this event, it couldstill be true that the dedicated line to these libraries, although expensive, could remain less costlythan dial-up.

As mentioned above, 66 libraries have been designated as using dial-up circuits for network access.These libraries were so designated either because they are open less than 20 hours per week orbecause they are located in areas where dedicated line access would be prohibitively expensive.The recurring (monthly) costs assigned to each of these libraries is calculated based on anassumption that the library will be dialed into the network for one-quarter of the hours it is open tothe public.

MLC will require dial-in facilities apart from the needs of the branches, in order to supporttelecommuting and remote network management. The cost of these lines and the associatedequipment is reflected in the cost figures of this document.

9. Equipment At The Endpoints

The budget for the bond sale proceeds financing the creation of this network includes $750,000 tobe used for the purchase of PCs to be placed in the libraries. This amount is over and above themoney allocated for networking hardware/software, and was based on the parameters of spending$3,750 to equip 200 locations.

It is recommended that each library PC have the following specifications:

Windows '95 PC, Pentium processor or better

Minimum 16 MB memory, 500 MB hard disk space

Color SVGA monitor, 15" or larger

Network adapter card for connection to router (dedicated line locations) or 28.8 Kbs datamodem (dial-up locations)

Sound card and speakers; one CD-ROM drive

At least 1 MB on-board video RAM

Libraries with existing PC networks will require a network card compatible with their existingnetworks; the cost for such a card (about $100) is not included in this project budget, and would bethe responsibility of the affected library. Such libraries may also require a larger router than the unitbudgeted for this purpose. In either case, libraries intending to connect more than one PC to thenetwork must obtain MLC approval for the additional endpoints, and for the connection ofadditional equipment to the network.

The PCs should be purchased with Windows '95 preloaded. Windows '95 includes the necessaryTCP/IP support required by the network. Before deployment, the PCs will need to be updated withthe chosen Internet browser and mail reader (such as Netscape 3.0 or some subsequent version),unless Windows '95 becomes bundled with such software in the future. Other software may benecessary, such as Win Shield protection software for public access PCs. Telnet software is highlyrecommended; this will allow users to access ASCII (non-graphical) hosts.

It is very important that MLC establish a policy with respect to allowing the libraries to add othersoftware to the network PC. The installation of some software could interfere or conflict with thenetwork hardware/software, and should only be done if approved by MLC. MLC will notguarantee support for PCs to which unauthorized software and/or hardware has been added. Inaddition, the MLC will be unable to support authorized add-ons to individual systems.

In addition, it is recommended that each library be given a choice of receiving a FAX machine or alaser printer, according to each library's needs. For the purposes of this choice, it should beassumed that the FAX machine and the printer are of equal cost.

As indicated earlier, each branch connected to the network via a dedicated line must be equippedwith a Cisco 1005 router and a GDC 553 CSU/DSU. It is critical that these devices be capable of

remote management. HQ libraries will receive a Cisco 2501 router and one (or two) GDC 554CSU/DSU(s).

At the library, it is recommended that all equipment be powered from a single power strip whichfeatures surge protection and a single on/off power switch.

If any of the libraries wish to connect additional PCs to the network, this can be done through theuse of simple, inexpensive wiring hubs into which both the router and the PCs would connect.Simple, five-port twisted-pair hubs cost less than $100. Note: no money for connecting additionalbranch/HQ PCs to the network have been allocated in this project budget. Any PCs or othernetwork hardware/software added by system libraries must be approved beforehand by MLCAutomation Services.

It is not recommended that individual printers at the HQs or branches be connected to the networkas network devices. Aside from the fact that network printers take up an IP address (see Section 7),adding a printer to the network should be done only if remote printing is done (i.e. it is necessary toroute materials from one network location directly to another location's printer). Given the otherdocument routing capabilities of this network (e-mail, FTP, etc), this functionality is not seen asrequired. Rather, local printers should be connected either to the local branch PC via its parallelport or, if present, via a Local Area Network print server.

Conceptual local connection diagrams are shown in Figures 10, 11, and 12.

10. Personnel Issues

As of this writing, MLC has added three staff members who will have primary responsibility for theproposed data network. Among the functions assigned to these positions are telecommunicationsnetwork responsibility, Webmaster responsibilities, and network support (help desk)responsibilities. These staff additions are seen to be adequate for the initial operation period of theproposed network. In order to get the network installed and running, however, it is recommendedthat MLC hire a limited-term employee or consultant to oversee the network installation (seeSection 12). Once the network is fully operational, additional network support staff may berequired as the population of devices, the use of the network, and the amount of MLC informationoffered on the network all increase.

The MLC network has been designed so that additional personnel at the HQs and branches will notbe required.

II. Training Issues

User training will be a critical issue in the overall success of the MLC network. The followingspecifications for the user training provided to public libraries follows:

Who should be trained: at least two representatives from each library (branch and HQs). Theserepresentatives should be the personnel who will actually use the network the most. It is notadvisable to confine training to HQ personnel and then depend on them to train the branches.

When training should take place: after a library's computer and network lines/equipment are inplace and ready to use, or as close to this date as possible. The training will not be effective if thereis any delay between the receipt of the training and the actual use of the network at the library.

Where training should take place: it is recommended that the training take place Jacksonwhenever possible. In support of this effort, it is recommended that a PC training lab be set up atMLC for hands-on training sessions. This lab can also be used to test and configure the PCs to beplaced in the libraries. The lab PCs should be connected to the network so that lab PC users willexperience exactly what they will see when they return to their home libraries. The cost for this labhas been included in the MLC equipment costs shown in Figure 5. The stated cost includes labPCs, and also includes an amount for "equipment and furniture". The latter amount is meant tocover a screen projection device, a screen on which to project the image, and tables for theworkstations.

On an ongoing basis, it is inevitable that MLC will be asked to provide one-to-one onsite training atthe libraries. This should be handled on a case-by-case basis. Given that onsite training should notbe done before a library's computer is attached to the network, this training could be done using thelibrary's own PC. MLC may wish to consider the purchase of one or more laptop computers forcases where a library is visited that does not have a working network station; these laptops wouldrequire a 28.8 kbs modem for dialing into the network, and should have color monitors. Requiredsoftware would include a web browser (such as Netscape) and dialup WINSOCK software, all ofwhich can be downloaded from the Internet at no cost. Such laptops are estimated to cost about$3000 each. The purchase of laptops is not reflected in the project budget.

Who should conduct the training: as much as possible, the training should be done by MLCpersonnel to the extent that these personnel have a reasonable amount of presentation skills.Specifically, the MLC Network Manager should provide the network training, and the personresponsible for the Help Desk should provide the troubleshooting and problem escalation portionsof the training. Anyone familiar with PCs can provide the basic, introductory portions of theprogram. If MLC deems that their personnel do not possess the required presentation or teachingskills, then an outside agency should be retained to conduct the training at MLC.

User Training Outline: It is recommended that all network users be given two days of training.

Day One, Morning Session

The first session of the first day would be devoted to concepts for users who have neverused a computer before; this session may be skipped for more experienced PC users. Thissession, anticipated to last 3 hours (one-half day), would include:

How to power on the PC and monitor;

Windows '95 basics: how to use a mouse (left button, right button, double clicks);opening/closing windows and boxes; finding files and programs; using the "Start" bar;opening multiple windows and switching between them; using pull-down menus.setting user/desktop preferences.

Basic computer troubleshooting; restarting the computer; most common problems

Using the CD-ROM and floppy discs; accessing/transferring files to/from discs; savinginformation; performing backups; protection from viruses.

Day One, Afternoon Session

Basic telecommunications principles: identification of components (router, CSU/DSU),indications given during normal operation (lights, etc).

Basic networking principles: defining the frame relay environment; dial-up versusdedicated lines; the principle of packet networking; IP addressing; the role of the router.

Establishing network connection. For dial-up users, this means initiating the telephonecall to MLC, while for dedicated users the network should always be available. It isrecommended that all users be exposed to training on both types of connects.

Logging into/out of the network; operation of network menus; overview of availableservices.

Day Two, Morning Session

Explanation of what Internet is (and isn't); components of the Internet (World WideWeb, discussion groups, electronic mail).

Mississippi Library CommissionData Network Specifications

Use of the Internet browser for Internet access and MLC database access; using Webforms and setting user preferences; hyperlinks; searching the Internet; settingbookmarks; common resources useful to libraries.

Accessing the Dynix system and other MLC applications.

Time for "exploring" and net surfing.

Day Two, Afternoon Session

Configuring the e-email program: users should be given their e-mail addresses, and beled through configuring their e-mail browser.

Composing e-mail; maintaining address book; sending messages; receiving messages;setting up file cabinets; replying to messages; forwarding messages; practice sessionwhere students send mail to one another.

E-mail etiquette.

Network support issues: common problems and their solutions; how to report aproblem; escalation procedures; how to best assist the Help Desk in troubleshootingproblems.

At the conclusion of the training, each participant should be given a notebook of training materials,including "quick reference" cards summarizing network operation and basic troubleshootingprocedures.

The complete, detailed training program should be started immediately. Training materials andprocedures should be tested during the HQ pilot phase (see following section) and appropriaterevisions made during the course of the network deployment. If possible, it is recommended thatearly training sessions be videotaped so that careful analysis and improvement of the classes maytake place. After the entire network is operational, it is assumed that the training program will needto be continued as new library personnel and new network applications are continually added.

Training For MLC Employees: Help Desk (and possibly other) MLC employees will requiretraining for all hardware and software purchased for the network. It is recommended that thistraining be procured, where possible, from the vendor(s). For example, training on the Spectrumsystem should be obtained from the Spectrum vendor. Less specialized training, such as forWindows NT, HTML page authoring, TCP/IP network management, etc, should be obtainedthrough outside courses selected from state-approved lists of third-party training providers.

Mississippi Library CommissionData Network Specifications

Other Types Of Training: there are some types of training which MLC should not offer until afterthe network is operational and the public libraries have all been trained on basic network operation.These additional training topics may then be considered for offer to the public libraries by MLC.

Advanced data networking: creating a LAN in a branch or HQ library; interfacing the LAN tothe network.

Training the public to use the network.

How to create/maintain/update a home page on the Web.

12. Network Deployment Issues

The proposed network, while completely feasible and of sound design, is nevertheless quitecomplex and will require careful implementation. It is recommended that a "top-down" method beused; that is, the central site (MLC) must be equipped and made operational before the"downstream network points" (i.e. HQs and branches) are added. The basic implementation stepsare:

1. Work with ITS to approve the plan constituted by this document. Continue to monitor theprocess by which the bond money (necessary to fund network startup) is released.

2. Install/configure all network hardware and software at MLC, with the exception of the Databaseserver and associated software (see Figure 13). The items to be installed include the Internetlink, the main T-1 s into the Frame Relay cloud, and the other MLC servers, software, andnetwork components.

3. Implement a pilot program consisting of approximately eight to twelve HQ libraries, includingtwo or three branch libraries who will use dial-up access. One HQ should be chosen from eachFrame Relay cloud. The chosen HQs should be ones that are already comfortable and familiarwith telecommunications, networking, and computer technology. However, one HQ that is notfamiliar with this technology should be included so that training and support issues can be moreeasily identified. Some of the dial-up branch libraries will probably not be familiar withcomputers. The following libraries are proposed as candidates for the pilot program, based onthe above criteria:

Mississippi Library CommissionData Network Specifications

Starkville PLRobinson-Carpenter Library, ClevelandPrentiss PL (dial-up)Itawamba County Lib, Fulton (dial-up)Shelby PL (dial-up)

4. Following the pilot program, the network should be extended to all HQs. It is recommendedthat installation of the routers be accomplished by the vendor; installation costs have beenincluded into the router prices. The PCs should be configured and tested at MLC, and theneither delivered to HQ or installed by MLC personnel.

5. Finally, the network should be extended to the branches.

MLC may wish to consider hiring a technical Project Manager to coordinate the networkimplementation. Although the MLC Telecommunications Specialist could certainly handle thistask, it is envisioned that the Specialist will have a great many other responsibilities during this time(such as helping to create training materials and working with the libraries). Also, it could beuseful to employ a person who has experience in actually setting up networks similar to the MLCnetwork. Hiring an FTE is not recommended, as it is envisioned that the Project Manager positionwould not be required after the network is created. No costs associated with such a position areincluded in the budgets contained in this document. As an estimate, a Project Manager who spentapproximately 20 hours per month for a period of one year would cost in the neighborhood of$25,000. This approach is recommended over depending on ITS for guidance; while ITS certainlyhas the expertise and would be quite willing to assist MLC, it is doubtful that ITS could devote thetime to MLC which would be required to assure a smooth installation. The cost of this ProjectManager is included in the project budget (see Figure 2 and Figure 14).

A diagram of this implementation, with a suggested timeline, is provided below:

13. Network Support Issues

MLC has already indicated its plan to create a "help desk" for support of network users. This planis highly recommended by the consulting team. The Help Desk would support both dedicated-lineusers and dial-up users (who, as outlined previously, will be dialing directly into MLC). MLCplans to purchase the Spectrum software package to manage the Help Desk function.

When users encounter operational problems, a clear line of escalation should be followed. It isrecommended that a user's initial call for help go to a designated primary or backup contact at itsHQ; most problems can be corrected in this manner. If that call does not resolve the problem, thenthe MLC Help Desk should be contacted.

It is recommended that Help Desk calls be tracked by the location initiating the call, so thatrecurring problems can be identified. Help Desk records should include a photograph of thebranch's network installation, which can be taken when the equipment is installed. Also, it isimportant that each library's CSU/DSU, router, and PC be clearly labeled with the unit's IP addressand with a label identifying the box (i.e. "Router", "CSU/DSU"). This labeling can either be doneduring installation or before installation, and will further assist the Help Desk in resolvingproblems.

14. Security And Firewalls

Securing the network environment requires that MLC establish a security policy that articulateswhat is acceptable and what level of access is available to patrons, library staff, and MLC staff.The security policy must be published to make sure that everybody is aware of their responsibilities.

Host systems and applications should provide access control using userid/password combination.New applications currently being planned (e.g. CD-ROM server) should be network aware andprovide application level security. In addition to application level security, network security may beprovided using firewalls.

The objective of a firewall is to protect one network from another network. In MLC's case, theobjective of the firewall is to protect unauthorized access from the Internet. The term firewall isused by many as a generic term to describe a wide range of functions and architectures of devicesthat protect the network. In MLC's environment, firewalls can be implemented by using packetfilters and proxy servers (also called application gateways).

At a minimum, MLC should use the Cisco 4500 that connects to the Internet as a screening routerusing packet filters. Incoming traffic (mail, FTP, Web) should be directed to only designatedservers (FTP/Mail, Web). The servers could be configured on a separate Ethernet segment to

Mississippi Library CommissionData Network Specifications

provide an added level of network separation. Packet filtering at the branch and HQ libraries maybe sufficient if there are no host services provided by those libraries. The dialup server at MLCshould be secured at a minimum with userid/password. Passwords should be changed at least onceevery 30-45 days.

MLC could choose to install a proxy server, which is generally stronger than packet filters. Proxyservers add considerable inconvenience for administrators and end users. Each application (e.g.FTP, Finger, HTTP, NFS, NNTP, SMTP, POP, etc.) that runs through the firewall needs its ownproxy. Some firewalls require every machine that communications through the firewall to runmodified client and server software. Those that do not require modified software require end usersto learn special procedures to negotiate through the proxy.

In our opinion, packet filtering and host based security (userid/password) is sufficient for initialimplementation. Proxy servers may be implemented at a later time if deemed necessary or requiredby state policy. Cost of a firewall that implement packet filtering and proxy services could rangefrom $15,000 to $25,000 (Vendors: Checkpoint Software Technologies, Lexington, MA Product:Firewall-1: Harris Computer Systems Corp., Fort Lauderdale, FL Product: Cyberguard 2.0).

We would recommend that technical staff periodically review system log information on the serversto assure that no unauthorized access occurs.

15. Next Steps

It is recognized by the Consulting Team that ongoing changes in the MLC's operating and fiscalenvironments will necessitate changes in the data network plan. Specifically, this plan could begreatly affected by federal/state legislative action (or inaction), other funding milestones,availability and pricing of services from Bell South, policy decisions by ITS, and changes inofferings by equipment vendors, to name but a few. These actions will require that the basic planpresented in this document be "fine tuned" to take best advantage of the changes. Examples ofthese changes could include which libraries are connected via dial-up or dedicated lines, whatspecific hardware and software is purchased, etc. In the absence of any changes, the ConsultingTeam believes that the plan presented herein is the best course for MLC to follow; however, MLCshould expect and plan for changes to this plan as the network is created.

16. Attachments

Immediately following this section is Figure 15, a detailed spreadsheet providing a library-by-library breakdown of the proposed network. This spreadsheet was used to determine the overallestimated costs for the telecommunications lines and library equipment costs. A detailedexplanation of the entries in this spreadsheet follows:

Mississippi Library CommissionData Network Specifications

The spreadsheet contains entries for all public libraries in the state, and is ordered by the librarysystem name (column 2). Within a system, the order is alphabetic by library name (column1). The city in which the library resides is provided in column 3.

The "# Of Loc" column has entries only for the HQ libraries, and counts the number of branchlibraries associated with that HQ.

The "# Of Dedic Loc" column also has entries only for HQ libraries, and counts the number ofbranch libraries within its system which will be connected to the HQ via a dedicated data line;this count includes the HQ itself. Note: any branch library whose local Frame Relay connectionpoint is different from the HQ's Frame Relay connection point (see following item) is proposedto be connected to the network through MLC in Jackson rather than through the HQ, and thus isnot counted in this column's number (example: Sebastopol PL connects through the MeridianFrame Relay cloud, but the HQ for this system, Florence PL, connects through Jackson; thus,Sebastopol is not counted in the 12 libraries to be connected to Florence with dedicated datalines). The remainder of the libraries within that system are proposed to be connected via dial-up lines.

The "FRelay Node" column shows which of the Bell South Frame Relay nodes serves thislibrary. The codes are as follows: Gp=Gulfport; Gw=Greenwood; Ha=Hattiesburg;Jk=Jackson; Me=Meridian; Mp=Memphis; Tu=Tupelo.

Libraries whose local telecommunications services are provided by Bell South are indicated by"S" in the "SB/IND" column; libraries served by independent, non-Bell companies areindicated by "I".

The "SB Mile" column gives the number of miles a library is from the borders of "localservice" for Bell South .Frame Relay service. Only a few libraries are not within local BellSouth service.

The "Ind Mile" column gives the number of miles a library is from the borders of "localservice" for a library not served by Bell South.

All libraries connected via dedicated lines are assumed to be connected to their HQ as a "hub"point. Libraries that are exceptions to this rule are those with an entry in the "Hub Location"column (see explanation for "# Of Dedic Loc" column above).

The "Dedicated Lines Install" and "Dedicated Lines Recur" columns give one-time costs("install") and monthly costs ("recur") for dedicated data line(s). Libraries with entries inthese columns are proposed to be connected to the network via a dedicated line. Mostlibraries are configured with a single 56 kbs Frame Relay line; HQs with more than eight

Mississippi Library CommissionData Network Specifications

dedicated-line branches are assigned two 56 kbs lines (see Section 8). The parameters used forthese charges are taken from values set at the end of the spreadsheet.

The "Dialup Line Install" and "Dialup Line Recur" columns give one-time costs ("install")and monthly costs ("recur") for a single analog dial-up data line. Libraries with entries inthese columns are proposed to be connected to the network via a dial-up line. Therecurring monthly cost is based on a standard state business line and the assumption that thelibrary will be dialed into the network for one-quarter of the hours it is open to the public (seeSection 8). The parameters used for these charges are taken from values set at the end of thespreadsheet.

The "Equipment Purchase" and "Equipment Maintenance" columns give prices for theequipment (one-time cost) and recurring maintenance charges for that equipment. Thisequipment is assigned as follows: For branch libraries connected via a dedicated line, oneCSU/DSU per line and one Cisco 1005 router; for branch libraries connected via a dial-up line,one 28.8 kbs modem; for HQ libraries, one Cisco 2500 router and one CSU/DSU per line. Therouter and CSU/DSU prices are automatically taken from the spreadsheet given in Figure 6,"Router/CSU/DSU Costs And Specifications" and include installation.

The totals for dedicated lines install, dedicated lines recurring, dial-up lines install, dial-up linesrecurring, equipment purchase, and equipment maintenance are automatically transferred to the"Network Cost Summary" spreadsheet shown in Figure 2.

Figure 16 shows a detailed blueprint for device public and private IP addressing (see Section 7).Figure 17 provides a detailed blueprint for WAN IP addressing (public and private). Figure 18provides detailed sample router configurations for MLC, HQ, and branch library routers.

The following additional materials are attached to this document:

1) "MLC Library Survey" document2) "Survey Results" spreadsheet3) "Option 1/2/3" network topology diagrams4) "Network Connectivity Options" spreadsheet5) "MLC CD-ROM Tower Specifications" document

These materials exhibits provide background supportive material relating to the factors whichinfluenced the decisions made in designing the network, but are not directly related to the networkdesign itself.

Mississippi Library CommissionCD ROM Tower Specifications

Section 7: Functional Specifications

A: General Description

The MLC desires to purchase a CD-ROM tower which will houseand allow access to its collection of CD-ROM databases. Thepurpose of the tower is to facilitate the use of thesedatabases by MLC employees (through in-house Local AreaNetworks) and by member libraries throughout the state(through the planned statewide telecommunications network).The tower will be part of both MLC's Novell LANs and thestatewide network. The statewide network will operate underTCP/IP and several routers and servers.

It is anticipated that this CD-ROM tower will include adedicated computer and specialized software to facilitate theaccess to the CD-ROM discs. Proprietary software foraccessing an individual disc will be loaded onto networkservers for general use; the client (workstation) softwarewill be standard access software such as a web browser orNovell client programs.

B. Minimum Requirements

The chosen CD-ROM tower unit must conform to the followingminimum specifications:

1) The tower must be capable of holding and providing on-line access to a minimum of 50 discs, with access to all50 possible without any physical loading of the discafter access is requested by the user that is, theunit should not be a "jukebox".
