EXECUTIVE SUMMARY
Rangitata Hospital is a private sector hospitalwhere they require additional infrastructure to give
more service to the people because they trust the brand of the hospital.It gives a framework to
identify, plan, deliver, improve and support IT services. It enables the organizations to provide
the services as per the business needs and goals. As an expert, we are giving a plan to the
hospital, a detailed plan and tragic way so that the hospitalamenities and the facilities can be
improved from the Existing infrastructure. Some people don't support the plan for the change
because of the fearof their roles inside the hospital might be automated and they might not be
needed to get into a problem so that they want the infrastructure to be in the organization and
provide the service to both the patient and staff.We are the Experts who are planning in the
existing infrastructure andeliminating the employees fear about the new environment.
The requirement of the change might happen any time because of the employee behaviour and
the new infrastructure might not give the optimal solution for the hospital due to some internal
factors inside the hospital, it will lead to some slacktime and some critical task that we must
analysis carefully to continue the work.We are using five-phasestrategy to plan and toachieve our
goal because not every change will be appreciated by all the people who might be affected inside
the organization.
INTRODUCTION
Rangitata Hospital is a private hospital which gives the best treatment to the patients with
the reasonable charges. So most of the patients prefer to visit the hospital and their count was
increased. They have to provide treatment to all the patients but there is less infrastructure to
give treatment to more number of patients. Due to an increase in the patient count, the count of
staff and administration staff is also increased. So the management has to take necessary steps in
changing the infrastructure of the organization. At present, the hospital has a building with a top
floor for patients. Due to the patient and staff growth, the problem arises in the IT network. The
network management team is finding the solution for network problem and they have some
requirements to change in the organization.
REQUIREMENTS OF THE ORGANIZATION
Patients records should be accessed by the medical staff by using laptops or desktop and
they need to access the information from the patient's room.
The network speed should be fast.
At present the LAN or WAN can connect to 30 laptops and the count of the laptop is
increased due to the staff growth so additional LAN should be added.
The network should be accessible from any floors of the patient's rooms.
They need a Single router to connect all the floors in the building.
They want to change the existing network infrastructure.
PART A
ITIL stands for Information Technology Infrastructure Library. It gives a framework to
identify, plan, deliver, improve and support IT services. It enables the organizations to provide
the services as per the business needs and goals. It clearly states the role of the Service provider.
ITIL can provide the service for any type of organization with various factors such as industry,
level and size. It provides a way between the IT organization and the business. It follows a set of
structures to maintain the organization. IT services provides a management plan for a different
organization such as health care, accounts for all services towards a business goal (ITIL, 2007).
In the ITIL there are five phases. They are
Service strategy
Service Design
service transition
Service Operation
Service Improvement
Service Strategy
This phase is one of the core parts of the ITIL lifecycle. It focuses on design,
development and implementation of the strategy. It provides the guidelines to the manager to
operate the process based on the constraints, governance and legislation. The main
target can alter the sensible higher cognitive process, supported a better understanding of the
provided services, with the final word plan of accelerating the cost-effective lifetime of entire
services. It is regarding making certain that organizational unit with the help of the
business square measure in a perfect position to handle the prices and risk related to the service
portfolios, which are found out for service improvement (ITIL, 2007).
The middle stage of the lifecycle in ITIL is service strategy, the creation of price starts with this
stage that understands the objective of client expectation. The quality structure includes process,
individuals and product that can support the service strategy. In ITIL service strategy provides a
perfect way for providing the service management with a structure to provide a strategic quality.
It describes the principles that provide the service management for developing the policies and
process towards the ITL services. The strategy is considered based on the following factors
Development of the infrastructure
Service assets
Internal and external providers
Hospital management
Administration
Financial management and
Risk factors
Service Design
In this second phase, the service is mainly focused on changing the service strategy into
the reality using the standard approach for the development of the service offerings such as
Regular use of a standard approach
Understand and translate business necessities
Identifying the suitable support for implementing the service.
The advantage of the service design does not restrict to add new service. It helps to make
changes and enhancement whenever necessary during the execution of the plan. Changes are
required to provide standard quality services to the customers (ITIL, 2007). Strategic design
should consider
Service management
IT and information security management
Service Transition
After completing the design and development phase, there is some service which is used for
providing the gap between the operations. This phase is called service transition phase which
helps to make changes during the life cycle of ITIL and transfers the service between the
suppliers and the customers. The Service Transition phase combines all the assets of a service
and ensures that the units are integrated and tested together. It mainly focuses on the standards,
management and delivery or replacement of the service into operations. Providing enough time
and quality to every stage of the life cycle leads to standard product and implantation of the life
cycles (ITIL, 2007).
Service Operation
The service operation team ensures that the provided service is robust and stable services. They
provide support throughout the process and a strong influence on business services. The
advantage of this group is they provide the direct service and support incident management for
fulfilling the requirement of the user by getting feedback from the user. Based on the user
stratification the requirements of the products are changed. Specifically, in IT there are separate
management teams for application, technical support to provide the successful solution for the
incidents that may affect the business services (ITIL,2007).
Continual service improvement
Continual Service improvement is worked based on the performance of the four stages of
the ITIL lifecycle to arrange the service with the customer satisfied business needs.
It provides the guidelines for creating and maintaining the strategy, service, design,
transition and operation to satisfy the customer needs.
It combines the principles, methods and practices from the quality and management to
improve the services.
It provides a better practice for getting improvement in quality service, efficient
operation, business continuity to ensure that the service group should associate to
business needs.
It also provides the guidance to improve the outcome of the service strategy, service design,
service transition and service operation.
Feedback from the customers is noted by using the Plan-Do-Check-Art cycle.
Feedback is obtained in all phases of the ITIL lifecycle that ensures to improve the
changes in any stages of the life cycle.
Nowadays in IT, there are different models and architectures like shared services, outsourcing,
utility computing, cloud computing, web services, virtualization and mobile commerce.
Similarly, ITIL uses the product based approach with the lifecycle to illustrate the challenges in
service management. The framework of ITIL is based on the five phases of the life cycle to
provide the better practice method for every stage. The guidance is based on the principles,
activities, process, technology, roles, challenges and risk factors.
The life cycle uses a separate design namely hub and spoke design. Among the phases, the hub is
considered as the service strategy and spoke as service design, service transition and service
operation. Here, continual service improvement supports in all stages of the life cycle. Each
stage requires the input and feedback from others. The same way, throughout the life cycle, they
have some set of check and balance to ensure the demand of the customers and the changes
required for the business needs. In addition to this, there are some set of ITIL publications that
provides a guideline to industry, organization, operation model and architecture technology.
(Open campus, 2017).
A quality management is a series of procedures taken explicitly to design the system that
can monitor, assess and enhance the quality and safety of the healthcare of a hospital, for
example reviewing patients, a survey on patient’s satisfactory, reporting, complaints and
situation handling, audits and compliance about quality. A proper quality plan has to be
established by the head of the hospital chief superintendent to ensure the quality and safety of the
hospital details as well as patients. These plans have to follow by all the service and departments
in the hospitals. These quality plans were prepared by hospital multi-disciplinary committee
under the hospital superintendent and these plans have the necessary information collected from
the staff members, prepared plan and established in cooperation with staffs at various level.
Quality management service documents were recognized, executed and maintained to meet the
quality objectives of the National Standard requirements. These documents of quality
management service contain Quality policy, Quality goal, manual about quality, Instruction and
procedure manual, Technical and operator manual. This quality manual describes the standard
operating procedure that is adopted in the hospitalConnect sphere (2017).
Continuous quality improvement (CQI)is to ensure the objective of the quality measures and
these involve on the safety, effectiveness, accessibility, efficiency and acceptability of the
service for their patients.
Steps for quality improvement
1. Monitor patient and staff satisfaction
2. The monitor of quality indicators
3. The monitor of Adverse Drug reactions and medication errors
4. Monitor patient safety indicators
5. The monitor of medical audit results
6. Monitor Utilization of Facilities
7. Monitor Patient Satisfaction Rate
STAKEHOLDERS
Doctors
The Doctors are the people who hold the information about the patients. These data are
stored in private in the private area.No patient is allowed to view the information of another
patient. The receptionist who is sitting in the front should be given access to the people who are
waiting to be cured but the receptionist should not able to see the information that doctors can
see only important role of the receptionist is that he or she should be able to update the
information about the arrival of the patient and match the information of the doctors availability
in the hospital.
In order to access the files from the stored place, we need routing protocols so that we only give
the necessary information for the people who need the information and who are authorized to
view the information. Doctors are the main people who bring the ROI Return on investment to
the hospital they need to be equipped with proper tools so that their productivity is maximized.
The networking system should be accessible at the multi-access point with multiple login roles
so that if one doctor needs to consult with another they can view the information easily .this
eliminates manual work with papers and person gives the files to be transferred from one place to
another place through a third person (Syed Amin tamish, 2005).
Patients
Hospitals which has the best equipment and the best doctors are responsible for the people trust
in that hospital more and more people will start to come if the quality of the service and
treatment of the patients are giving a huge response .for the best possible service the hospitals
must have the best networking system .so that all the document which is sent and shared from
one branch to another branch or one room to another room should be done in a very quick
manner. They should have resources to access that data so fast as possible (Syed amin tamish,
2005).
Government
Government tend to have information where how many people are going to the hospitals and
what are they are getting treatment for this will give them the analysis of the people how the
people are using the service from the hospitals. Government is one of the key stakeholders .they
are responsible for the quality controls in some hospitals some treatment has to be authorized by
the government .because the government must check that hospitals in which the patient is getting
treated will equip with the proper infrastructure. For example, if some disease is spreading the
government may inform the other people in other places that this is happening and they are
taking necessary actions .in order to provide the information to hospitals .the government will
have that technology. the hospital should be planned with the necessary information that could
be taken in the emergency point of time (Syed amin tamish, 2005).
Administration members
The Administrator whois in charge of the servers and the networking monitoring should have
access, not just a system but a high-speed system in order to move the data from one place to
another if will reduce the manual work (Syed amin tamish, 2005).
IDENTIFICATION OF FORCES OF CHANGE AND STABILITY
In some hospital, we need to expand the infrastructure in order to open the new facilities
and amenities that can be provided by the hospital in order to do that environment should be
flexible so that we can make the changes that we need. for example, we require a networking in
the storeroom in order to check the inventory. Our network should be capable enough to provide
the networking faculties around the campus (The Ipswich Hospital, 2013).
Management
There is always the management constraint in the hospital actually because the if the
supplier of the medicine does not have the requirement of the monthly stocking of the
medicine .doctors and staff will have difficulty in treating the patient because of the lack of the
medicine if this issue to be solved we need a proper system which gets updates day by day so
that the medicine might be given in the right time if there are too many stocking the inventory
some of the medicine may go waste if there is a lack in the supply we can treat the patient. In
results, the patient is satisfied with the hospital management (The Ipswich Hospital, 2013).
FORCE OF CHANGE
1. In some hospitals in to function them as a unit, they have a separate set of rules that are
applied throughout the campus the people can come to the hospital through a unique number
which is assigned to them. It can be checked online with the application or the monitors that
the hospitals use to show the display in the waiting room.
2. The lack of speed in the hospitals will reflect in the patients waiting in the room for a longer
will and the treatment specialities have to wait some more for the people to get started
We have now the requirement and a clear idea to do the project with the rapid change in the
environment. It is clear from the case study that the requirement of the computing power and
networking power will change from time to time. In order to satisfy the quality of the matter, we
need to give the suitable requirement and infrastructure to maintain the quality of service(The
Ipswich Hospital, 2013).
1. Our first goal to communicate with other people where the people need not go from one
place to another in order to send the information. While we are on the process of upgrading the
thing we need to inform the people what is going on the hospital what they have to do in order
to give the requirement to the different people at different time. Some time the Existing system
might be affected while performing this action the Requirement should be clear in the hospital
that these functions in the hospital will not work at a particular time. In the middle of the
treatment if the network failure it could lead to serious consequences these are thing should be
counted before upgrading the infrastructure and the network (The Ipswich Hospital, 2013).
2. After building the network we need to train the staff because the requirement from the
doctor, patient and from the management will change .at any moment the doctors may ask the
network people to give access to the files at the night because of his busy schedule and might
ask to take back regularly inside the network. If there is nobody to monitor the thing the data
might be corrupted in the network. The system engineer should be responsible for any data loss
or any data breach. The system should be secured in the way that nobody in the hospitals has
access to the information that they should have access (The Ipswich Hospital, 2013).
3. The frequent meeting should be done in order to adapt to the changes in the environment.
This change will take some time for the other people to adapt especially for the newer people
who have joined in the hospital at recently.
In this project, we are making use of the Lewin's Change Management Model, Because we can
build the system according to the requirements it is used to do major change in the system, If
there are sudden un-change people in the organization may not like that change they like to stick
what they and know and they like the way that they do things. In order to make people more
reliable to the change, we can use two techniques that are by unfreezing and Refreeze model
(The Ipswich Hospital, 2013).
Unfreeze we need to speak to people who this change will affect what additional role they might
be doing or what other roles they will be concentrated on when the changes get reflected .for
example if the attender is making the notes of the appointment and doctors availability is writing
down somewhere. Here we are considering this to be a change in which how they are able to
write everything down on the computer. So that it can be shared with other people so easily.
Next, we have to deal with the change so people might have difficulty is adapting to the change
we need to help the people.
We all are human beings and we make mistakes. So we need to set the thing straight to the other
people who might try to spread some rumours inside the organization. So we need to have met
with other people so that we try to understand why there is a change in the system and who is
beneficial to them (The Ipswich Hospital, 2013).
REFREEZE
After the implementation, we need to check the overall performance of the employees after the
change and before the change. Of some department or a person is finding difficult we need to
teach and train the person to adapt to that change. This model does not give the performance
when there is change it a takes time and the environment to give the expected output of change
after the months of implementation (The Ipswich Hospital, 2013).

Existing Network Diagram of Rangitata Hospital
The existing network system has a single router that is connected to ten segments, which
is used to serve the internet. The routing information protocol version 1 is followed in the router.
The same server is used as of in floor 1 as a back-end server.
Routing information protocol version 1 (RIPv1) is used in the hospital, these protocols use a
local broadcast system to share the information about routing data (Thomas, n, d). As it is
assigned in a periodic manner for every 30 seconds the updated information about the router will
be stored. A single destination (Thomas, n, d) in RIP has a six equal paths.
Every 30 seconds routing updates were sent periodically throughout the broadcast using the
target IP address as limited IP address broadcast with 255.255.255.255 (Thomas, n, d). The
updates were sent using the target system IP address of the limited broadcast IP address. All the
message is needed regardless to the router as this will check whether it is running on the routing
information protocol version 1 (RIPv1)or not, this does not accept an authentication of the
updated message (Justin Deng Siheng Wu Kenny Sun, 2014).
The current system is slow to communicate and it is not efficient to carry the requirements of the
hospital. As all the medical staffs prefer to be communicated and connected to the medical
system using PC’s or Laptop’s, computer equipment’s from the patient’s room and scan rooms.
As every detail of particular patients like medical records, prescription, history of patient’s
medical details, new patient’s records and scan results like blood, x-ray or CT scan. These details
are sensitive as well as accessing this becomes a difficult part of their daily routine. Slow internet
on the hospital will lead to taking more time to upload data which can hang the system as well
(Justin Deng Siheng Wu Kenny Sun, 2014).
A wireless LAN will allow the staffs to access the system all at once at anywhere anytime in
their place. Anyone can access the patient’s necessary data anywhere any floor/ level 1 to 10.

The IP network topology used on the current system is of class C that offers 255 IP network of
the class of C IP address. These IP address of class C IP address on each floor states that each
floor can have as many as the computer’s as the IP address ranges available from 192.168.1.0 to
192.168.1.255. But the total system in the hospital is 65 this states that 189 addresses were
wasted. If the hospital management, wants to add some PC’s then one can extend by assigning
the additional address to them (Justin Deng Siheng Wu Kenny Sun, 2014).
Enhancement in terms of Switching Speed
The current network infrastructure has a centralized data center where staffs, as well as
patient’s details, were stored. These data’s were either in text format or in image format. All the
communications in the hospital were through the server so chances for traffic is expected to be
high. To make a speed network in the hospital a higher speed and the latest devices were used at
the data center. A single router on the hospital takes time to process the data so to make even a
better a separate router can be deployed at each department so that processing time can be
achieved but it is ideal to create as well as more expensive (Fiber optical networking, 2017).
The effective way to make the higher speed network in the hospital can be achieved by
deploying switches on each floor. The current network system uses separate switches on every
floor and uses a virtual LAN technology to get connected with the network. The LAN growth
depends on the level of computerization used by the hospital members. As the current network
topology is a star were a fibre cable can be expanded between each building? ALAN
Architecture has to design in a hierarchical manner to enhance the speed on the interconnected
device. The core layer, Distributed layer and access layer, these each layer will perform a
different task to make the speedy network. Core layer will handle the switches where switching
packets as fast as possible along with connection of LAN backend, firewall. A centralized server
or a data center contains a core layer with high-speed cables to make an ideal and speed
connection. Distribution layer will handle the switches and router task as this layer will have the
connection between the core layer and access layer. The access layer is where an end-user uses
to work with internet, a switch or hub is used to connect each PC’s in the floor through the same
LAN as redundant link usage will give high accessibility and availability on the network (Fiber
optical networking, 2017).
Layer Process
Access Layer Aggregates the end user from a different workspace.
Provide uplinks to the distribution layer.
Checks the authentication to access the device on the building.
Service: Broadcast protocol filtering, access the network, IP multicast
and quality of service.
Distribution Layer Provides access from the access layer to the core layer.
Implementation of of routing protocol.
Find the suitable path to transfer packets.
Steady connection even if one router point failure.
Core Layer High-speed connection between the layer and data centers (server).
Ensure the high reliability and availability.
In addition to this, Rangitata hospital uses network switching to enhance the speed of the
switches to increase the speed. Switch configuration on network switching is modular, fixed and
stackable. Each switching configuration has its own advantages as modular gives more flexibility
in configuration, the fixed configuration is fixed as no changes were made, whereas stackable
switches give high bandwidth. Stackable switch connections have interconnected with cables
(Fiber or high Ethernet cable). This can give high bandwidth on the switch and it is preferable
among most of the applications as providing high availability and fault tolerance. Modular
deployment the switch is expensive (Fiber optical networking, 2017).
Pros Cons
Modular High availability features.
Modular design
Supports a wide range of line
card.
Easy to deploy.
More space.
Expensive to deploy.
High power supplies.
220v power for PoE solutions.
Stackable Pay what you have (can add
additional devices)
Virtual capability.
Cross-stack Ethernet cable
Difficult to manage
Power supply
Software complexity
Uncertainty
To make the network speed in Rangitata hospital, it is highly recommended to replace with the
high-speed device on the server and use modular switches. Avoiding traffic on the server end
will give an ideal path to transfer packets and modular switches on every floor will handle the
whole floor as it will give a high range to line cards to connect every PCs. Even though it is
expensive to deploy, it gives a cost-effective as it keeps activate for a long-term unlike stackable
switch which needs periodic maintenance that is more expensive when compared to modular.
The performance of the modular switches is good, cost-effective and low power consumption.
Modular switches are preferable and recommended as each entity in the hospital need data access
of high data availability can be achieved on the modular switch (Fiber optical networking, 2017).

The class C subnet mask is used in Rangitata hospital; it has a 24-bit network prefix. 1-1-0 is the
highest order bits that are set followed by 8-bit host number and 21-bit network number. IPv4
addresses are used in the present system and the above table represents the IPv4 addresses. The
additional system can be added as each floor can have 254 PCs.
Recommendation in terms of routing protocol
A routing protocol uses a routing algorithm to find the suitable path that will determine
the optimal path on the network to transfer data and a communication path between two network
nodes. Routing protocol will enable the communication in the router and whole network
topology is easy to understand.
EIGRP stands for Enhanced Interior Gateway Routing Protocol which is an advanced protocol
used for finding the distance network routing and configuration. RIP and IGRP is a vector
protocol whereas Enhanced Interior Gateway Routing Protocol (EIGRP) is more than IGRP as it
is link state protocol. This is easy to deploy and fast merging, most of the large enterprise uses
EIGRP to enhance the network speed by the fast and optimistic method to find the path. Both
IPv4 and IPv6 address method can be supported by the easy transition. It uses a diffused update
algorithm to find the shortest path on the network. This is used as it is best method to establish
the balance between easy management, speed and scalability. The Enhanced Interior Gateway
Routing Protocol is different from other protocol through the following,
Different subnet masks length.
Support multiple layer protocols.
Support partial updates.
Faster convergence.
For Rangitata hospital, EIGRP is recommended as it is more flexibility than other routing
protocols. As said it uses diffusing update algorithm that will automatically decide the optimistic
path and calculates a loop-free path as an ideal method to determine routing path and routing
interface (Justin Deng Siheng Wu Kenny Sun, 2014).
Wireless LAN Access Design
As network infrastructure is needed to improve their services in Rangitata hospital, the
use of WLAN (Wireless LAN) will help them to use and access the data using wireless. A
wireless LAN uses it assesses point to access the client request for the wireless channel. Both the
controller and access point is needed to deploy WLAN (Techopedia, 2018).
WLAN controller will combine the traffic from the access point; this will regulate, inspect and
deliver it to core LAN. To improve the high-speed network in the hospital these controllers were
placed in the datacenter as this will clear the traffic on the server. These controllers on data
center will give high performance on the current networking channel as it runs on centralized
WLAN like client management, encryption, roaming between the access points and mobile
controller domains and access point controllers (Techopedia, 2018).
For Wireless LAN (WLAN) access point, as this serves a discrete traffic collector that will
refrain and adjust with wireless traffic to mobility controller of a wired connection. The wireless
access point allows a user connectivity and radio coverage to communicate with server and user
device. And this also can act as the surveillance device that regularly monitors threats
(Techopedia, 2018).
The only way to reduce the traffic on the router is to deploy a separate router on each floor but it
will be more expensive. So to do this wireless access point is used on every floor as this access
point act as a wireless router at each floor that allows a wireless device to connect with the
network. The mobility controller on the data center will have different access point as a built-in
the router and these access points are critical because the Wi-Fi signals are only propagated only
for short distance. A scaled plan of constructing the optimal access point spacing through skills
will help to design a proper system. The thumb rule of accessing point spacing is around 75
feet’s, to design a better network infrastructure using access point then the overall design of the
building structure is analyzed some obstacles like room scale shield, concrete walls can weaken
the radio signal used in wireless channels. Some rooms like obstacles were specially designed
the infection-controlled room so the penetration of signals through ceilings or walls to place new
cables (Techopedia, 2018).
Once the place is visited then designing to implement the network should be analyzed. This
analysis will help to place the access points, antennas, routers, switches, other network materials,
mounting hardware and a proper instalment manual has to be present (Techopedia, 2018).
Risk factor
The current infrastructure in Rangitata Hospital has a risk factor as an inaccurate
assessment of the network structure will affect the whole system that leads to the
ineffective system.
As using Cisco products it allows only to support with Cisco products as it does not allow
with other market vendors. It will be expensive when more entity has to repair. And
repairing Cisco products EIGRP enhanced interior gateway routing protocol allows and
support only the Cisco product as other vendors were declined to produce the product.
As medical staff does not know how to work with the new system it takes time to get
adapt to the new system and it depends on individuals how fast they can learn.
Security to protect patient data is the main factor as data leakage will affect so
maintaining data confidentiality is an important task. Improvement in server-side security
will allow the staff members to access the patient’s data anywhere.
As the system uses the wireless channel for communication and access to data there is the
chance for an outsider could access the system. So a security bridge can also be a risk
factor.
Additional system connection needs changes in IP address which takes time to reconnect
the whole system. So for additional system configuration or connection, the changes in IP
address will affect the whole network system until proper connection. The network
permissions and constraints will also be reviewed and changed.
Network Plan implementation
A new network system infrastructure design for Rangitata hospitals is expected to change
every one of the server, switches, and routers that are presently conveyed in the Rangitata
hospital facility. Execution of the newly proposed network system will need the arrangement of
the fast-Ethernet switches on each level of the hospital. All these switches will be the recipient of
the system network data packets and will equally forward all the bundles of packets to the PCs
ring connected to it. The PCs present inside the ring is connected to each other through the LAN
wired-network (Freshservice, 2018)
The association among frameworks of systems to a switch is made conceivable over with fast-
Ethernet cables or gigabits cables. Fast-Ethernet or gigabit Ethernet will create a fast or high-
speed network channel among the entire network system. A personal computer amplifier will be
introduced at the building floor that is far from the switch with the goal and thus the availability
will be improved. The no of customer's frameworks that shifts from 10 in the seventh floor and
some on nearly 50 in the first floor can be part of many rings that will be associated by spans.
Deploying 5 to 10 PC's framework on each floor according to their needs, are associated with
wired and the other PCs were associated with an access point as a remote connection (wireless
connection). By doing this one can get access to numerous system on each different floor and
extra additional system including or add will be simple during reconnecting all (Freshservice,
2018).
In addition, the individual remote or wireless access point will be introduced and deployed in
each floor, each passage or access point (AP) on each floor which will act as a perfect or ideal
switch on each different floor. The wireless router will likewise be introduced or added
additional and will be connected to the communicated (broadcast) association. By doing this, the
PCs utilized by medical staff’s, doctors and specialists can get to effortlessly the server
information (Freshservice, 2018).
Records sharing should likewise be possible, and the new system can augment associated device
like fax machines and printers. A network system connected storage will likewise be introduced
as reinforcement as a careful step for information loss (Freshservice, 2018).
As far as Routing Protocols EIGRP is taken after and the best away is switching speed practices
will be utilized. When the network system is completely set up, the security settings of the
switches, routers and the server OS will be explored that the system is secured. Remote and
wireless encryption convention will use to encode packets information. Hospital staff who are
authorized and approved to access to the server data and nobody can be accessed and modify
protection settings and browser security (Freshservice, 2018).

Resources
To implement the new network system in Rangitata hospital an experienced technical
expertise needed.
Equipment such as routers, switches, amplifiers, medical equipment’s, PC’s or Laptops
and other necessary materials to implement the network system.
Budget and investment are needed as this can make an effective and efficient
infrastructure can be made.
PART C
After completing the implementation of the planned changes in Rangitata hospital, the outcome
of the network plan is given below:

Replacing RIP with EIGRP RIP is shifted to EGRP according to the plan
even though the hospital is running on daily
events.
Establishing a connection between the
hospital staff to the server from anywhere
and anytime on the patient files.
The connectivity between the server and staff
computer is given as per schedule and there
is no problem with the connection
Project evaluation
Planned Actual
Time – 31 days Time – 31 days
Budget - $20100 Budget - $22,000
The project is completed within the actual date
and the budget is increased from $20!00 to
$22000. Since the technicians worked with some
disturbances and they completed the work so the
cost is increased.
Corrective Actions Implemented
The project has been completed as per the schedule. The only changes that occurred are
budget is increased due to some disturbances faced by the technician and they required additional
cost. Since changes that should be done in the hospital without closing it. So there will be a lot of
disturbances to the staff, patients and technicians. The staffs and patients have coordinated for
the changes that should be done for their betterment and they prepared themselves to adapt to the
situation. It was a challenging role for the technicians to find the perfect place for fixing the
cables, access points and WLAN etc. They clearly understood the structure of the hospital and
completed the installation successfully.
Improvement action implemented
After installing the required network components the team has monitored to make sure
that all is going well. At one instance they found there was the server down and they identified it
is due to heavy load in the network and they cleared the problem by restarting the server. After
that, it worked properly. The hospital gave the feedback about the work. It was good and the staff
felt that there was no problem in uploading the files. If any problem occurs they will contact the
team immediately.
Evaluation
The team did good planning based on the requirements of the hospital. They visited the structure
of the hospital and they worked accordingly. Before executing the plan they were clear about the
deadline and efficient work. The resources are used based on the hospital needs. There is a
separate team for monitoring the network components to know the progress of the modified
network infrastructure
Recommendations
To hospital
The network components should be maintained often.
The data backup should be available since network failure can occur at any item.
If there is any problem with the system, it should be reported to the team immediately.
To team members
The network infrastructure should be implemented within the estimated budget.
The technicians should work under any circumstances.
Overall the project should be completed within the requirement of the hospital andthe
estimated plan.
