Rangitata Hospital 

Rangitata Hospital is a private hospital which is experiencing growth in patient numbers. This growth has seen a growth in the number of staff, patients and administration staff in the organization. It is based in a building, which it owns, and has recently started using the top floors as patient rooms (previously they were empty). There are several problems with the IT network that have occurred because of the growth. The IT director, Alex, is responsible for network management and is seeking a solution which will meet the requirements of the hospital. He has the following brief which outlines the business requirements of the hospital.

Medical staff prefer to be connected to medical systems by laptops and they require access to the network from any patient room. They need to be able to access patient medical records, x-rays, prescriptions, and the latest patient information.  Alex has already installed servers and located them in the data centre which is located on the ground floor. Alex reports that users have expressed criticism of the slow speed of the servers.  The current wireless LAN (WLAN) covers 30 laptops, and 15 others are to be added in six months’ time. The current network cannot cope with this number of laptops.  Patient rooms are located on floors 6 to 10 of the hospital building. The network should be accessible from any floor.  Alex recommends there be a single access point in each communication room which can cover all rooms on that floor (there is a communications room on each floor).  The current network consists of ten segments connected to a single router which serves the Internet as well. The router runs Routing Information Protocol Version 1 (RIPv1).  Alex has provided a table which contains the current IP addresses. (see table 1, below).  Alex wants the network enhanced by using fast switches which will make quicker access to the servers.  The new design must guarantee secure WLAN access on floors 6 to 10.  An IP addressing outline that cuts the number of Class C networks used by the hospital needs to be included.  Alex also wishes to cut the number of the networks leased from the Internet service provider (ISP).

Answer :



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 hospital amenities 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 and eliminating 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.


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. 


  • 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.


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 processsupported 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

Monitor patient and staff satisfaction

The monitor of quality indicators

The monitor of Adverse Drug reactions and medication errors  

Monitor patient safety indicators

The monitor of medical audit results

Monitor Utilization of Facilities

Monitor Patient Satisfaction Rate



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).


 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 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).


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).


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)


  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).


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 (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.

Hospital’s Existing IP Address 


IP Network


No.of Clients































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 to 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)



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)




  • 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.


  • 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).

Project evaluation



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. 


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


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.
