COIT20264 Network Design (Term 1, 2018)
Assessment Item 2 - Written Assessment
Due date: 11:30 pm AEST, Friday, Week 12 ASSESSMENT
Weighting: 60% 2
Length: No word count limit
Objectives
In Assessment Item 2, you will complete your final network design report for the scenario given on page 3 based on the written and oral feedback you received on your Assessment Item 1. Please refer to the Unit Profile to understand how this assessment item relates to the Unit Learning Outcomes (ULOs). You are expected to participate in the weekly discussions and find the answers to the recommended discussion questions. The weekly discussion questions have been selected and formulated not only to gradually increase your knowledge and skills in this unit but also to help you develop the logical and physical network designs. If you do not attempt weekly discussion questions, you would very likely produce a network design that would not satisfy the requirements and/or that cannot be justified.
Requirements
Starting from the logical design of the network that you completed in Assessment Item 1, you are required to undertake the physical design of the network taking into consideration the feedback that you received in Assessment Item 1.
In order to undertake your physical design, you may need to make further justifiable assumptions. You also have to complete your final network design report. It should also contain a brief reflection justifying how your work in this unit has satisfied the unit learning outcomes. The reflection should be supported by the agreed outcomes of the weekly discussion questions. Please refer to the unit profile to see how this assessment item relates to ULOs.
Your report should include the following:
1. Executive Summary
2. Table of Contents
3. Project Goal
4. Project Scope
5. Design requirements
a. Business Goals and Constraints
b. Technical Goals and Tradeoffs
c. User Communities and Network Applications
d. List of Assumptions
6. Logical Network Design
a. The logical network diagrams including addressing and naming
b. The explanation and justification of your logical network design
c. The list of routing and switching protocols, and security mechanisms
7. Physical Network Design
a. The final network diagram
b. The table of networking & communication devices and applications required, including the cost of each of them, the IP addresses, the product numbers as well as the approximate total cost
c. The explanation and justification for the selection of the devices and applications required
d. A test plan that can be used to test the new network
e. One detailed test script for your test plan.
8. Brief Reflection (maximum two A4 pages): Justify how your work in this unit has satisfied the Unit Learning Outcomes. For your justification, you should use your contributions to the weekly discussion questions as supporting material and provide them in the appendix. You also need to include one thing that you liked about this unit giving the reason. Also, suggest an improvement to the unit with the justification. Use the list of headings given below for your brief reflection:
a. Prepare the user, business and security requirements of the organisation in relation to network design.
b. Analyse the user, business and security requirements.
c. Compare and contrast the possible alternative logical and physical network designs.
d. Design a network by applying the top-down network design methodology.
e. Create the final documentation of the designed network.
f. Justify that the designed network satisfies the requirements.
g. One thing you liked the most about this unit.
h. One suggestion to improve the unit.
The report must follow Harvard citation and referencing guidelines.

You need to familiarise yourself with the marking criteria to ensure that you have addressed them when preparing this assessment item.

The Scenario for Network Design Assessment Tasks
Your company in Australia specialises in designing networks for local and international clients. Your company has signed a contract with Cosmos online newspaper publishing company located in Sydney, Australia to design their network.
Cosmos has a global network of reporters who report news from every corner of the world. Customers who are interested in reading the online newspapers and watching live video feeds have to register with Cosmos and pay a small fee online. The major income generator of Cosmos is the advertisements which contain live and playback videos in some instances. Cosmos accepts any type of advertisement from companies and individuals as long as it complies with the media codes, guidelines and regulations in Australia. It is estimated that 100,000 people will access the newspapers of Cosmos every day at the beginning and it will increase to 500,000 within 3 years.
Cosmos plans to provide its 40-50 freelance reporters with suitable telecommunication devices for live reporting from areas where the Internet connectivity is poor or unavailable. The permanent staff of Cosmos consists of a CEO, a Finance Manager, a HR Manager, a Publishing Manager and a Technical Manager assisted by 20 supporting staff. The CEO, the HR Manager and 6 staff members are located on the first floor and the rest of the permanent staff is located on the ground floor of the two storey building. Cosmos has to provide a secure and reliable service to its permanent staff, customers, advertisers and the freelance reporters. Their website and video feeds should be available 24/7.
Using the top-down network design methodology that you learned in this unit, design the network of Cosmos, including the selection of telecommunication devices for the reporters. You are allowed to make assumptions if they are really required for undertaking your network design. Each step of your network design should clearly explain and justify how you satisfy the requirements of Cosmos.
Note: This scenario was created by Dr Rohan de Silva on 5th December 2017 and no part of this scenario should be reproduced by any individual or an organisation without written permission from CQUniversity, Australia.
