Case Study – Nuffield Group of
This case study presents a scenario in which the Nuffield group of Hospitals in
Scarborough has hired you to design their network. The following case study
description will provide you the scenario and customer requirements.
2. Project Scenario and Requirements
The Nufflield group of hospitals is distributed over four sites in Scarborough.
Each site is a specialist treatment center and is functionally autonomous. There
are five GP surgeries in the area that offer primary patient care and service. Site
1, which is the Main Site holds the centralized patient and administration
database. According to the new Heath Service directive on area-wide health
service unification, the four hospital sites and the five GP surgeries should be
networked to enable access to the centralized patient database.
The IT group manages the network administration at the Main Site and overseas
the other sites. The CIO (Chief Information Officer) who ran this group and
overall network has left because of political wrangling. This new CIO has
agreement with other hospital sites that there should be one routing protocol, as
opposed to the three that are currently running. He has also agreed to
implement efficient addressing, improve network performance, grant some basic
security and improve user experience.
The sites implement wired network that should support growth over next five to
2.1 Statement of Requirements
The task is to design, implement and document the proposed network solution
that meets the objectives, as described in section 2.1.1- 2.1.4, to improve
overall network performance and security. You are required to compile your
solution into a formal report and present it to the client.
2.1.1 Network Layout
2.1.2 Address Requirements:
Address the network using the private network address 10.0.0.0. Design the
addressing scheme so that it supports VLSM and allows for the summarization of
addresses. Show the summarization that you allocate with reasons for your
Site 1 uses a prefix of 22 bits
Site 2 uses a prefix of 28 bits
Site 3 uses a prefix of 24 bits
Site 4 uses a prefix of 24 bits
Use a 30 bit prefix for WAN connections to GP surgeries
The routing protocols configured on different sites are as follows:
Site 1: EIGRP 300
Site 2: OSPF
Site 3: RIP
Site 4: EIGRP 200
You solution is required to implement a single routing protocol across all sites so
that networks can see all routes.
Note that sites running EIGRP are running different autonomous system
numbers. Your solution should consider approaches to transition to using a single
autonomous system number.
2.1.4 WAN and Internet Access
At present all hospital sites have basic WAN connectivity and have their own
connections to ISPs for Internet access. Your design should propose and discuss
options available for Internet access and WAN connectivity with due
consideration for cost effectiveness and improved performance and efficiency.
3.0 General Group guidelines
The students should organize themselves in groups of two (maximum 3 if
one odd student is left without a peer).
Group members should make a clear statement of the division of
responsibilities at the beginning of the project and inform it to their tutor
and post it on the blog.
When conducting elicitation activities, each member of the group should
investigate details relevant to their responsibility on the project.
When making project presentation, the group members should present
their contribution to the project.
4.0 Project Deliverables
The two main deliverables from the project are:
4.1 Project report (~ 2000 words): one report per team is to be submitted
as a hard copy and also saved on your group blog on the NILE. Sections
5.1.1- 5.1.9 describes report structure.
4.2 Project presentation
Each member of the group should contribute to project presentation and
5.1.1 Problem Analysis and Design
The background information and system specifications provided in the problem
brief have purposely been left abstract to encourage investigation. You will be
required to investigate all aspects of the problem domain, which will
Carry out elicitation interviews with project stakeholders such as the CIO,
IT technician, a general system user and Medical Director.
Define scope of the system and lay the foundation for the further stages of
design and implementation, based on original brief and relevant problem
domain information extracted during the elicitation phase of the project.
Document interview responses and include them in an appendix with the
The design documentation should reflect and relate to your investigation.
You may extend the specification in any way thought appropriate; but any
such extensions should only be attempted if the key project stakeholders
deem them appropriate.
5.1.2 Network Design and Diagram
Once a complete understanding of the problem domain has been achieved, you
must produce the technical specifications corresponding to user
Translate technical specifications to utilise an appropriate selection of techniques,
tools and methods to develop the prototype design and solution.
Produce a logical network diagram that includes:
Router names and interface details
Spare block/s of addresses available for future use
WAN connection types and speed (data rate)
Note: The diagram should be drawn using professional drawing software,
such as Microsoft Visio using appropriate networking icons.
5.1.3 IP Addressing
You are required to produce IP addressing scheme that is efficient and would
contribute towards improving network performance. Discuss your design and
document it in a tabular form as shown below.
Subnets that will not be used are to be clearly identified in the table. For subnets
that are not used enter “Spare” as the network name.
Sample IP Address Table
No. of Max
Network Name Hosts Possible Network Address Subnet Mask
5.1.4 Routing and Transition.
Discuss, explain and implement transition to single routing protocol for all sites.
As the routing protocols are aware of multiple paths to destinations, your design
should also provision for optimal path selection
5.1.5 WAN and Internet Access
Your design should discuss WAN options available to interconnect the four sites
and also the GP surgeries and implement the proposed solution. Discuss whether
choice of WAN option is influenced by security requirements in the specifications
5.1.6 Implementation and Testing
Implement the proposed design in the Packet Tracer or using network hardware.
Include packet tracer based implementation with the report.
Evaluate your network design and implementation against requirements of
improved network performance, security and cost effectiveness.
5.1.8 Project Management
As this is a group work, the members on the group would need to communicate
and collaborate on the project to deliver the required objectives. A blog will be
created in the course document area on the NILE for each of the group to submit
Students are encouraged to use collaboration tools on MyPad on the NILE to
facilitate communication, collaboration and liaison on the project outside guided
class hours, which could be used to evidence activities that relate to project
