1. Introduction

This document describes the research-based assignment for this module. This assignment consists of two parts:

1. A formal report
2. And a presentation

2. Purpose of the assessment

1. To enable students to design a network by applying the theory and practice of networks, network operating systems, and network technologies they have learnt.
2. To enable students to select appropriate networking technologies for particular environment.
3. To enable students to design a simulated network with LAN, WAN and Internet functionalities.

3.Organisation

This coursework should be undertaken individually. Students should apply the theory and concepts that they have learnt in the class, and are advised to research extensively by using the library, browsing the internet and other resources on the data communications in LAN, WAN, inter-site networking, NOS's and network technologies underpinning good network design and management to computersry out this assignment.

a. Overview

This assignment presents a scenario in which the XYZ COMPUTERS Company has hired your team to design their computer network. In order to help you organize this project, the scenario has been divided into seven phases listing the requirements for each phase. You have to accomplish each phase and prepare a formal report that can be given to the company.

This assignment requires that you accomplish the following:

1. Identify the Network Components for XYZCOMPUTERS.
2. Identify the topology and technology to be used for LAN/WAN Interconnectivity
3. Identify the Network media to be used.
4. Identify the Transmission equipment to be used
5. Determine the protocols, and the NOS to be used.
6. Perform VLSM design.
7. Provide detail documentation in the appropriate format.
8. Provide a written report.

b. Scenario

Satyam Computers is a newly established company that sells computers accessories. It has a chain of stores in four cities namely Kuala Lumpur, Ipoh, Penang, and Johor Bharu. Each store is housed in a building with Sales, Purchase, and Marketing and Administration departments in separate floors or rooms. Each employee has his/her own computer with access to Internet.
The company is implementing a wired network that should support 10% scalability over the next five to ten years. Your task is to design and document the network that will meet the requirements Satyam Computers.

c. XYZ Computers requirements

1. Each store has a LAN with separated subnet for each department and all the four individual stores LANs are connected into a WAN.
2. Each subnet has its own server and a printer.
3. Assume an IP address for connection to the Internet router.
4. Assume any public Class B Network IP address for internal addressing.
5. Use a VLSM for IP addressing.
6. All networking devices must have an IP address.

i. Kuala Lumpur

• 18 employees in Sales.
• 9 employees in Marketing
•  7 employees each in Purchase and Administration.

ii. Ipoh

• 9 employees in Sales
• 5 employees in Marketing
• 4 employees in Purchase and Administration

iii, Johor Bharu

• 15 employees in Sales
• 7 employees in Marketing
• 5 employees in Purchase and Administration

iv. Penang

• 12 employees in Sales
• 5 employees in each Marketing, Purchase and Administration.

4 Deliverables

The Deliverables consist of the following (contribution to the overall module mark is given in brackets):

a. A formal written report containing

Phase -1: Satyam Computers Network Composition.

1. Outline
2. Summary of the Companies Network requirements
3. Identify all the network components that would be included in the Satyam Computers network.

Phase - 2: LAN/WAN Interconnectivity

1. Identify the LAN and WAN topology, and technology you would recommend and give the rationale behind.
2. Create a table as shown below, and enter the network devices/components that you would be using in the Satyam Computers network under the corresponding layers they function in the right column

 Phase -3 : Physical Transmission options

1. Identify the network media you would recommend to use in Satyam Computers network for the interconnection of devices, LAN and WAN.
2. Briefly explain your reasons behind which should include pricing, bandwidth needs, and equipment needs.

Phase - 4: Transmission Equipments

1.  Identify the transmission equipment like routers, switches and other transmission equipments that you would use in Satyam Computers network to provide LAN and WAN connectivity.Explain in brief the reasons for using those devices that you have identified.

 Phase -5: Network Protocol Architecture.

1. Based on the requirements of Satyam Computers and which NOS you would recommend. Briefly explain your reasons.
2. Determine which LAN and WAN protocols are supported by the NOS you recommended.
3. Create a table as shown below, and enter the protocols under the corresponding layers they function in the right column.

Phase -6: Routing Protocols.

1. Identify the routing protocols that you would recommend for the Satyam Computers  network. The possible routing protocol alternatives and properties should be identified in a brainstorming session. Each property is assigned a numeric value from 0 to 4. A recommendation be made and the decision matrix should be presented in the report as shown below.

Group recommendation for Routing Protocol:

Phase -7: VLSM Design

1. Your team has decided to use VLSM to maximize the use of IP address. Produce a table showing all possible subnets that meets the Satyam Computers requirements using VLSM.
2. For each location, a set of tables for the Switches and Routers should be given as shown below.

 Phase -8: Network Design

Produce a logical diagram that includes:

1. Router Switch Names
2. Router Interface Details
3. Network Addresses
4. Number of Hosts per Network
