Introduction

APIIT Law School is established to provide law degrees in Sri-Lanka from end of

2009.This new law school will be established in a newly purchased 5 floor building

nearby the APIIT main City campus.

The business interaction and the IT infrastructure of the new law school will be

independent from the main campus.

The proposed computer network should be able to provide high speed access to the

internet and also a connection between main campus and the new law school also

should be established .the sharing of the network also should be controlled according to

the different users .

The proposed network should be crash proof and should consist of backup plans in

case of a network failure.

3


Assumptions

o The assumption that cost in not a major issue was taken into consideration.

o We assumed that single point failures will not occur often.

o We also assumed that there are no technological constraints.

Network Plan

Main diagram

Shown in the following page is the main diagram of the proposed network system. The

whole network is proposed to be set on a hierarchical manner. This will help the network

administrators to maintain the network cost effectively and easily. So in case of a

network failure the network can restore in a less downtime or without interruption

because it’s easy to find where the error occurred. Also with the hierarchical approach

the network can easily expand without unnecessarily cabling the building again. Also

the location of each department can be easily changed with this approach.

Internet Connectivity

We proposed leased line connections compared to ADSL and Wi-MAX connections

because according to Dialog Telekom PLC (2008) Wi-MAX broadband is a shared

bandwidth services so actual speeds may vary due to many factors like internet traffic,

selected plan, so there will be no static speed.

But according to Sri-Lanka Telecom (2008) leased lines are dedicated connection so

speed will be fixed and it’s monitored around the clock to provide the highly reliable

uninterrupted service.

We proposed to use two leased lines - one leased line dedicated to internet and other

leased line is a VPN leased line and its dedicated to VPN to the main campus. We use

two dedicated lines because the Law school will use more than 200 wired and wireless

devices and most of the devices will connect to the internet on the proposed network, so

the institute will require higher internet bandwidth, if not the connection to the internet

will slow down .Also we need higher bandwidth because of the VPN and the VoIP

implementation. If we didn’t propose a high bandwidth internet connection the Voice

Quality of the VoIP will be drop down and the VPN connection between main campus

and the law college will be slow down so both voice and data services will be

interrupted.

Load Balancer

According to Syme, M and Goldie, P in their book “Optimizing Network Performance”

they say that when dealing with multiple internet connections load balancer needs to be

used to connect the multiple links simultaneously.

We proposed to use a load balancer because with the load balancer both leased line

connections can be used at the same time, also if management wants to add more

internet connectivity they can easily connect the new connection to the load balancer

without rewiring the premises.

7

http://en.wikipedia.org/w/index.php?title=Matthew_Syme&action=edit&redlink=1


If one connection fails, with the other link the internet connection can be accessed.

Firewall

According to Dr. Alkharobi, T (2007) in his book “Firewalls” defines that a firewall is a

dedicated network device positioned on the boundary of two or more networks which

filters all traffic entering or leaving the connected networks.

We proposed to use a hardware firewall because hardware firewall uses the packet

filtering, that means check the packet and determine whether packet should or should

not forwarded to the internal network but in software firewalls it can only block unsafe

applications which connects to the external network. So hardware firewalls have more

enhanced security controls.

DMZ (Demilitarized zone)

According to Dr. Alkharobi, T (2007) in his book “Firewalls” describes that a zone with

an intermediate trust level, situated between Internet and a trusted internal network is a

demilitarized zone (DMZ).

We proposed to use a demilitarized zone because servers in the DMZ are placed with

their own subnet, so if a network attack comes through the internet the attacker can only

access the DMZ and the internal network will not be attacked and the rest of the

network will be protected. So we placed servers like application server, e-mail inside the

DMZ which are exposed to the users from the external network so the internal network

can be protected from attacks.

8


Proxy Server

Proxy server is a server that sits between internet and the internal network which

provide security, administrative control and cache services.

We proposed to use a proxy server because of its abilities of:

Content filtering

Bandwidth management

Cache services

IPPBX

IPPBX is the equipment that helps to switch calls between the traditional phone line and

VoIP.

Internet Security Systems (2004). VoIP: The Evolving Solution and the Evolving Threat.

United States: Internet Security Systems. p1-p6.

We proposed to use a IPPBX as a part of VoIP implementation because IPPBX is an

essential network element for the VoIP implementation.

Backbone Switch

For the backbone switch we use a 48 port layer 3 switch. We are proposing to use a

layer 3 switch to the backbone switch because according to Allied ,T (2005) “Layer 3

switches” as their whitepaper it describes that layer 3 switches are capable to do

switching and routing on every port in high speeds and can handle high bandwidth of

traffic than layer 2 switches

To the backbone switch servers, internet connectivity and other switches are connected,

so through the backbone switch high bandwidth of traffic goes in and out. Also traffic

should be routed to the destinations.

9


Servers

We mainly use several servers in our network proposal they are:

Domain Controllers

Database Server

Application Server

Printer Server

E-Mail Server

File Server

DNS Server

DHCP Serverg

VPN Server

SIP Server

Domain Controller Servers

According to Microsoft TechNet (2008), in their knowledge base it describes domain

controllers can authenticate users and assign permissions on the network.

We proposed two domains to students and staff to separate the network features

among the students and the staff and for authentication purposes. So there will be two

separate logins for the staff and students. With proper authentication methods the

unauthorized access to the network can be reduced.

E-Mail Server

We proposed to use an E-mail server to provide e-mail services to the Law school and

staff with their own domain name. (Example: - [email protected])

10


Printer Server

We proposed to use a printer server than printer sharing because with a printer server

you can manage the printer all around the network and can accept print jobs from the

client computers. Also with the printer server it can grant and restrict the use of printer

for users. Users will be able to take printouts from anywhe8re around the network and

users do not need to install and load the printer drivers for each machine.

Database Server

Database server can keep the databases and provide database services to the

organization. We are proposing a database server because software like student

information and student payment details will be kept on a centralized database, so a

database server should be established. Also for the software development purposes

students may need a database management system, so with the client computers users

can use database services.

File Server

The main purpose of using a file server to keep the files in a centralized storage location

is so that it can be access by the client computers. So Course Materials and other

documents can be kept on the file server.

11


DHCP Server

DHCP servers can assign configuration information to DHCP clients automatically.

Nominum Inc. (2000). DHCP whitepaper. United States: Nominum Inc.p1.

We are proposing to use a DHCP server to assign client computers to obtain their

TCP/IP network configurations from this DHCP server so the network administrators do

not need to manually configure TCP/IP settings to each computer.

This will reduce the manual work of network administrators and optimize efferent use of

the IP address. If we are not using a DHCP server network administrator have to

configure each network devices TCP/IP settings manually. In this large network it’s not

possible and not cost effective.

DNS Server

According to Hallberg, B (2005) in his book “Networking: a beginner's guide” DNS

server can translate a domain name to its host name. For example to convert apiit.lk

domains to its IP address , DNS server can cache and store the query results and every

time it to not need to accesses the root DNS server to do the translation process

SIP Server

SIP server enables SIP end points to exchange messages, register user location, and

provide routing and security policies for VoIP implementation.

RADVISION Ltd (2004). SIP Server Technical Overview. United States : RADVISION Ltd. p1-p3.

We proposed to use a SIP server because we are planned to implement the VoIP

services so SIP server is an essential network element for the VoIP implementation.

12


VPN Server

VPN server is a server gateway that manages, authenticates and connects VPN clients.

anonymous.(2005). Virtual Private Networks. Available:

http://www.ebitsolutions.net/services/networks/vpn_faq.htm. Last accessed [14 Sep

2009].

We proposed to use a VPN server for the linking of the main campus and the APIIT law

school we use a VPN connection and we need to manage and authenticate the users

who connect in and out though the VPN.

13


First floor

Floor Plan briefing

Respectively first floor will have the reception, accounting department and the counselor rooms.

Network Plan

Figure 2 – Ground Floor Plan

14


As shown in the above figure the main switch in the ground floor will be connected to

the backbone switch in server room though the air vent. Two switches will be connected

from the main switch to the accounting department and to the counselor rooms and

network equipments in those departments will be connected to them .Wi-Fi router and

reception PCs and Reception IP Phone will be directly connected to the main switch.

We proposed a separate Layer 2 switch for the level 1 floor to keep the hierarchical

approach and the keep that floor work independent from other floors. All other switches

in this floor will be connected to that main switch and this main switch will be connected

to the server backbone switch.

We use a separate switch for the accounting department because if the management

wants to move the accounting department to another location and have a different office

in that place the network can be easily expandable without changing the wired

connections, also by having a separate switch accounting department can be

segmented and work separately and can assign several network configurations only for

that department.

Equipment briefing

We are suggesting using a 24 port and 12 port switches which are IEEE 802.3, 1Gpbs

or 10Gpbs standard switches.

15


Account Department wiring plan

Figure 3 – Accounting Dep. Wiring overview

The above figure shows the proposed wiring plan for the accounts department.

Backup and Recovery Plans

Maintaining the network of this floor can be done without interfering the other floors of

the network by using a separate main switch to this floor. In case of a failure, network

administrators can easily come up with the solution and with a less down time without

interfering the network connection of the other floors.

16


Second floor

Floor Plan briefing

As shown in the figure below human resources department, library and the study area

will be located in the second floor, expect that there will be a lobby.

Network Plan

Figure 4 - Level 2 Floor Plan

17


Follows the hierarchical approach and to separate the floor there will be a floor main

switch and from that other switches in that floor will be connected and there will be

separate switches to library, study room because in the future the network can be

expandable.

Equipment briefing

We are suggesting using a 24 port and 12 port switches which are IEEE 802.3, 1Gpbs

or 10Gpbs standard switches.

18


Third floor

Floor Plan briefing

In the third floor the labs and the server room will be located.

Network plan

Figure 5 – Level 3 Floor Plan

As shown in the figure above the lab backbone switch will be connected to the server

backbone though the air duct, each lab will have its own switch. Each switch will be

connecting to 40 computers using star topology.

19


Equipment briefing

Each lab will have two interconnected 24 port switches, 48 or 64 port switches, we

proposed to use more port switches than the available network equipments because the

lab can be expandable easily.

Lab wiring plan

Figure 6 – Lab wiring overview

The proposed wiring plans for the labs are shown in the above figure. Computers will be

divided into 10 rows, 4 computers in each row. Nearby each row there will be a wall

outlet and cabling from the computers will be connecting to it. Cables from the wall

outlet will be connected to the patch panel and from the patch panel those cables will be

20


connected to the Lab switch using patch cables. All the network devices in the labs will

be connected to the switch using star topology.

21


Server room

Figure 7 – Server Room

22


Forth floor

Floor Plan briefing

In the fourth floor all the class rooms are located.

Network plan

Figure 8 – Level 4 Floor Plan

As shown in the figure above the level main switch will be connected to the server

backbone though the air duct there will be shared switches in the class rooms, that

23


would mean that one switch will be used in two class rooms. We use switches in class

rooms considering a future network expansion, or a backup situation.

Equipment briefing

We propose to use IEEE 802.3 standard 12 or 24 Port Layer 2 switches which support

1Gpbs or 10Gpbs.

24


Fifth floor

Floor Plan briefing

Fifth floor will have the meeting room, conference hall, staff room, CEO office and a store room.

Network Plan


As shown in the figure above the hierarchical approach is followed and there will be a

main switch for the fifth floor and other switches are connected to it from it, we provide

25


separate switches for meeting room, and conference hall because in the future if these

location have to change the network can be easily expandable, we provide a separate

switch to staff room because there will be lot of network devices and in case of a

proposal to use two interconnected switches in the staff room. Also we propose to keep

a free cable to the store room because if the store room is to be used for another

purpose in the future it will have to be rewired again. Also we use two wireless access

points in the lobby of the fifth floor and for the conference room.

The staff room network components will be connected to the staff switch using the star

topology, also in the CEO office as well.

All the cables will connect to the backbone switch though the air duct.

Equipment briefing

All switches in this floor will be IEEE 802.3 standard layer two 12 or 24 port switches, in

a requirement staff room can use a 48 port switch or two interconnected 24 port

switches.

Backup and Recovery Plans

We proposed to use two 24 port switches in the staff room if one switch goes down the

full network in staff room will not go down.

26


Sixth floor

Floor Plan briefing

Respectively the sixth floor will be the cafeteria.

Network Plan


27


As shown in the above figure there will be a main switch in the sixth floor, and the

wireless access points will be connected from the main switch. We proposed to use two

wireless access points to give a good wireless coverage in the sixth floor .also we

provide a wired connection to the canteen counter.

Equipment briefing

We propose to use IEEE 802.3 standard 12 or 24 Port Layer 2 switch as the main

switch and for the wireless access points we propose to use 802.11g or 802.11n

standard wireless access points.

28


VoIP

According to Internet Security Systems (2004). VoIP: “The Evolving Solution and the

Evolving Threat “ whitepaper Voice over Internet Protocol (VoIP) is a service that

delivers voice services over an IP network.

The figure below shows the VoIP implementation in APIIT Law School. We are

proposing to implement VoIP services in this network proposal because the same

network can be used to transfer both data and voice .VoIP will cut down the cost of

implementing an internal telephone system and it provides many features than the

normal telephone implementation.

Figure 11 – VoIP implementation

29


For moderation and management purposes APIIT law school staff may need to contact

Staffordshire University and APIIT Malaysia frequently, so with the implementation of

the VoIP staff can make calls to foreign countries for lower prices than the traditional

telephone system.

With the VoIP expanding the telephone line is really easy than using normal telephone

connection. If the management wants to have extra phones connections to be

implemented in the Law school premises they only need to plug a VoIP phone to the

nearest switch or a use a VoIP soft phone. If we use the old telephone system we have

to newly wire the new locations to take the telephone connection.

VoIP has many features like Voice mail, Caller ID, Call Conferencing, Call forwarding,

Number Portability which we have to pay extra service charges to the service provider

in the normal telephone network .

Internet Security Systems (2004). VoIP: The Evolving Solution and the Evolving Threat.

United States: Internet Security Systems. p1-p6.

Cabling

For cabling solution we propose 3 options

Cabling using CAT7(Category 7) Cables

Cabling using CAT6(Category 6) Cables

Cabling using CAT5e(Category 5) Cables

The following table shows the type of cabling and the maximum achievable speed

Cabling Type Achievable speed

CAT5 100Mpbs

CAT5e 1Gpbs

CAT6 1Gbps

CAT7 10Gpbs

Table 1 – Cable type and maximum achievable speed

B&B Electronics (2002). Ethernet basics . Ottawa,United States: B&B Electronics. p1-

p5.

Following table shows the cabling and its life cycle

Cable Type Lifecycle of System (Years)

Cat 5e/Class D UTP 5

Cat 6/Class E UTP 7

10G 6A UTP 10

TERA-Class F/Cat 7 15

Table 2 – Cable type and life time

Siemon (2008). Cabling Lifecycles and Total Cost of Ownership. United States: Siemon.

p2-p7

31


As the above table shows the CAT5 cables has a life cycle of only 5 years , also CAT 6

cables will be outdated in 7 years time.

Nowadays most organizations in Sri-Lanka use CAT5 cabling and achieve a maximum

speed of 100Mpbs, but the modern world is moving today towards achieving 1Gpbs

using CAT5e/CAT6 cabling and within the next 15 years the world will move to high

speed connectivity solutions of 10Gpbs using CAT7 cabling.

CAT 7 Cabling

Bob Grow, Chair of the 802.3 working group, in his recent announcement declared that

10Gpbs Ethernet over copper interface is now a standardized as IEEE 802.3ak.

IEEE . (2004). New IEEE standard adds copper cable interface to 10 gb/s

Ethernet. Available: http://standards.ieee.org/announcements/pr_8023ak.html. Last

[accessed 13 Sep 2009].

So for future purposes we suggest to use CAT7 cabling to the organization because

with CAT7 cabling you can easily upgrade to a 10Gpbs (IEEE 802.3ak) network without

rewiring the building. This will help the organization save a large sum of money and

also without an upgrade downtime.

But the current network devices will not support IEEE 802.3ak standards and the law

school will not receive the full advantage of the 10Gpbs networking, but in future it will

be a big advantage for the organization and company network as it can use under

10Gpbs speed without rewiring the building and only by replacing network devices .Also

CAT 7 is backward compatible and works with lower speed devices also.

If company management offers resistance to use CAT7 cabling we proposed to use

CAT5e or CAT 6 cables as an option, with the CAT5e cabling it will not make any

difficulties to work on with the current network background .

32


CAT 6 / CAT 5e Cabling

According to David, B in his book ‘Complete Guide to Network Wiring‘ he describes

CAT 5e an enhanced version of CAT5 cabling and capable of transmitting up to 1Gbps

speed.CAT 6 also support 1Gpbs Speed, both CAT5e and CAT6 cabling are backward

capable .

Law school cabling can be done using CAT5e UTP cables, for the cables that connects

floor switches to the server backbone switch which are running in the air vent can use

STP or UTP cables with PVC cover used as insulation. We propose to use insulation

covers for cables because most of the meager electrical cables running though the air

went are prone to electrical interference and if anything happens the data will be

corrupted. Also the PVC insulation cover will protect the cables from animal bites and

weather conditions.

33


Wireless access

Every floor in the law school will have secure wireless access and each floor will have a

wireless access point. We are proposing a wireless access point in every floor to give a

good wireless service by proving a good coverage .Each wireless connection will be

secured with a password to prevent unauthorized access.

We encourage establishing the wireless access point in the middle of every floor to

provide a 360 degree coverage in the floor. If the wireless access point is established in

a side of a floor some areas in that floor will not be well covered and users will face slow

wireless connections.

Standardization of Wireless Network

The IEEE standards that concern wireless local areas connection (WLAN) falls under

IEEE 802.11 we proposed to any of following standards in the network and the wireless

devices which provide wireless access should meet the following standards .

IEEE 802.11g

IEEE 802.11n

IEEE 802.11g

According to Black Box (2008). Wireless Networking Whitepaper, IEEE 802.11g is a

standardization stack (Combination of 802.11a and 802.11b), supporting up to 54 Mbps

bandwidth and its backward compatible with old standards. That mean wireless access

point with IEEE 802.11g will support to work with 802.11b wireless adapters.

34


IEEE 802.11n

According to Black Box (2008). Wireless Networking Whitepaper, IEEE 802.11n

supports up to 100Mpbs data rates and higher, better signal intensity than older

standards, is backward compatible with other standards. Also the Special feature is the

ability to support the utilization of multiple wireless signals and antennas instead of one

(MIMO technology).

Black Box (2008). Wireless Networking. Pennsylvania : Black Box. p1-p4.

35


Linking the Campus

As the managements request we have to bring up a link between the APIIT main

campus network and the proposed APIIT law school building. So we propose several

options for this connection.

Virtual Private Network (VPN)

Wireless Point to Point Bridges (PtP)

Virtual Private Network (VPN)

According to MegaPath Communications (2005). ‘Implementing an IP VPN’, in their

whitepaper they say VPN is a technology that can connect private networks with the use

of a public network such as the Internet.

Virtual Private Network can be used to link the APIIT City campus and the APIIT Law

School over the Internet which is located in two different physical sites, so these two

networks can be operate as a single network. This will benefit the organization by

sharing and centralizing the data in these two networks.

We propose to use VPN to link the two networks because, there is no special

infrastructure to be implemented, and with the current leased line you can link the two

LAN networks.

36


Figure 12 - VPN implementation

To keep the VPN Network on standard we proposed to use the following best practices

and to consider about these key areas when implementing the VPN network.

Traffic Control and bandwidth management and should guarantee the reliability and

performance of the VPN, use of security techniques like authentication and encryption

methods, and the implementation should guarantee the security of the network because

there may be private and confidential data like student personal information travelling

though this VPN .

MegaPath Communications (2005). Implementing an IP VPN. Costa Mesa, CA: MegaPath Communications. p2-p9.

37


Wireless Point to Point Bridges (PtP)

Figure 13 - Wireless P2P Bridge

Using a Wireless Point to Point Bridges we can connect the wired APIIT Law School

and APIIT City campus network wireless using two wireless bridges via IEEE 802.11g

Wi-Fi protocol or IEEE 802.16 Wi-MAX Protocol.

This method is easy to implement but using this method there will be lot of interferences

by weather and other effects. This wireless bridges should be line of sight, if not the

connection will drop, also the static speed cannot be guaranteed because of the

external inferences.

Standardization

Structured Cabling Standards (ANSI/TIA/EIA-568)

Most of the networks face problems because of inferior cabling of the network so we

propose to use structured cabling standards in the proposed network plan. This will

provide various benefits for the network and the network administrators.

So we proposed to use commercial building cabling standards which are provided by

American National Standards Institute (ANSI).

According to American National Standards Institute (ANSI) (2006).’Commercial building

telecommunications standards’ whitepaper cabling in commercial buildings falls under

ANSI/TIA/EIA-568 also this approach can be divided in to several main parts.

Entrance facility

Main Interconnect

Backbone distribution

Horizontal connect

Horizontal distribution

Work area

Entrance facility

The entrance facility contains the cables from the service provider. The connection and

the hardware equipments like CSU/DSU, IPPBX will be located here. The entrance

facility will be located in the special section in server room.

Main interconnect

The main interconnect will be the server room which is located in third floor. The cables

from the service provider and the cables from the floors (backbone cables) all the

servers will be connected to the Server backbone switch in the main interconnect .

Backbone distribution

Figure 14 – Backbone distribution

According to above figure the backbone cables will be distributed from the main

interconnect (server room) to every floor.

Horizontal distribution

Connections to the wall outlet fall under here. It’s proposed to use a maximum distance

of 90m and additional 10m for patching.

Working areas

This describes the connection from the outlet to the work area equipment, according to

this standard it’s proposed to use 3m of cabling after the wall outlet.

Backup Plans

Dual backbone switches

Other than one layer 3 switch we propose to use two layer3 switches in the server back

bone because if one switch goes down the network can be restore using the other layer

3 switch.

Remote backup

To guarantee the security of the confidential data we proposed to use a remote backup

or an online backup system. We don’t keep a backup server in the law school premises

because in case of a disaster like fire the backup server will be destroyed and backup

will be not useful.

Backup lines

To use in case of an emergency we can keep backup lines to the floors though the air

vent. If the current cable goes down the network can be restored with the emergency

line.

Limitations

Cannot overcome single point failures.

No proper media streaming facilities.

VoIP services are limited to voice services.

Conclusion

The purpose of this project was to implement a network plan for the APIIT Law School.

After several weeks of research we came up with solutions and new technologies that

could be useful to implementing the network. The use of all our research in this system

provides a network that is very effective and provides optimum features in the best way

possible.
