Turling Associated Limited
Case Study Overview
This case study presents a scenario in which the Turling Associates Company has
hired you to design their network.
1
Project Scenario
Turling Associates Limited is a small to medium size organization that
manufactures and markets high-speed wireless products. Its head office in
Lincoln is distributed over two buildings - main building and administration
building. The main building houses Sales and Marketing Group, and the Research
and Development Group, while the Administration building houses the
administration group. The offices for Research Group and the Sales and
Marketing Group are located on all three floors of the main building. The
company’s also has a remote sales office in Stamford.
The network diagram provided to you in Figure 1 is more demonstrative of logical
connectivity required in the new design
In addition to a formal report, the company would like the demonstration of the
prototype network, before a go ahead on the project is indicated.
2.
Statement of Requirements
The task is to design a computer network for the company to connect different
departments in the head office in Lincoln as well as to connect head office to
remote office in Stamford. The detailed specifications for the proposed network
are described in section 4.
You are also required to implement your design on a prototype network, and test
and demonstrate the functionality to the client.

Network Requirements:

Main Building LAN
o
18 employees in the Research and Development group VLAN.
o
9 employees in the Sales and Marketing group VLAN.
o
Administration LAN has 6 employees.
o
Remote Sales branch LAN has 5 employees.
o
Expect 100% growth of current IP requirements when
determining size of subnets.
o
Max number of 5 servers (regardless of company growth) which
are to be on their own VLAN.
o
The three switches are to have admin IP addresses assigned (on
the admin VLAN, VLAN99).
Note that each of these VLANs will require a separate subnet
o

Location of employees is also provided as given below:.
o 8 Research personnel and 2 Sales personnel are on Floor 3.
o
6 Research personnel and 4 Sales personnel are on Floor 2.
o
4 Research personnel and 3 Sales personnel are on Floor 1.
o
Floor 1 also has the Server LAN. Five server machines are
planned but at this time only one is available.
o
There is sufficient space in each room to accommodate growth.
o
The 100% predicted growth will occur uniformly per floor.

Switches in the building should provide for redundant connectivity so
that at if one switch fails an alternative path is used.

Address 150.13.2.0/30 is available for connecting to the Internet.

Use 195.10.7.0 for addressing on the internal network.

Design IP addressing scheme for efficient use of addresses.

A DHCP server will be used to administer IP addresses to
PC/workstations on the network.

Consider provision of static routes and default routes where necessary.

Discuss options available for connecting the head office and the branch
office. Suggest a suitable alternative.
If you need any further information from the client, please see your
tutor by appointment.

Project Deliverables
Following are the three deliverables from the project:
1. Report
Your project report (~ 2000 words) to the company should be submitted as
a hard copy and saved on a blog on the NILE. The structure for the report is
explained in section 6.
2. Implementation
Document router and switch configuration files, detailed test schedule
and test outputs. You may use Cisco hardware or simulation program
such as Packet Tracer or any other appropriate software to simulate and
test functionality of prototype network. Router and switch configuration
files and test outputs should be added as appendices with your report
3. Oral Presentation, Demonstration and Viva
Each student will present and demonstrate network functionality to the
rest of the group during one of the teaching sessions. You may use
power-point and/or packet tracer or other presentation and
demonstration.

Report Structure
Problem Analysis and Design
a.
Produce a project brief to describe the main technical requirements
the project.
b.
of
Produce a logical network diagram that includes:

Router and switch names

Router interface details

Network addresses

Number of hosts per network

Spare Network Address block/s
Use a suitable drawing software, such as Microsoft Visio or e-draw for network
diagram.
c.
IP Addressing
The sample table given below may be used to document IP address design.
Identify the unused subnets as spare.

No. of
Hosts

d. Routing protocols
Use a suitable routing protocol to implement the network. The diagram suggests
the use of OSPF as the routing protocol. You may however use other routing
protocol and justify its suitability for your proposed design.
e. VLANs
Design VLANs for the Main Building. You may document switch information as
given in the table below:
Sample Switch Table
Switch Name
Model
# Ports
IP Address
Gateway
f. Evaluation
Evaluate project outcomes against client requirements.
g. References
