20% (Marked out of 100 marks)


Type A

Assessment Objective

  • The report helps you grasp the fundamental concept of network design and acquire the knowledge on the techniques required for developing both logical and physical network designs.
  • The presentation enables presentation, oral communication and team skills to be exercised as well as providing an opportunity to research a specific topic.
  • Learning Outcomes Assessed:
    • K4. Describe the technologies and architecture of LANs, Wireless LANs and WANs.
    • K5. Identify the principles of LAN design.
    • A1. Analyse and design LAN architecture for organisational requirements.
    • S1- Analyse data communication and networking technologies in today's Internet.

Network Design Case

Accurate Accounting is an Australian regional accounting firm having three local offices located in Sydney, Adelaide, and Queensland. The company is constructing two adjacent buildings: (i) a three-story office building comprising 80 rooms and (ii) a single-story administration building with 20 rooms in Victoria as its main headquarter. The office building houses 80 computers, with additional 20 computers in the administration building. You are required to design a network (LAN) for the Victoria headquarter enterprise campus, which connects the three local offices. Therefore, you need to consider the WAN access in the LAN design for the headquarter enterprise campus.

The new network will house a data centre, the e-commerce edge, and 8 printers. 6 printers will be installed in the different rooms of the office building, while the other two are to be installed in the administration building. An employee is allowed to have a printing service with any printer through the new network. Employees will bring their own mobile devices (e.g., laptops, smartphones, tablets) to work. Employees will use them to access required information such as their work email, required documents, and Internet through wireless communication facilities (Wi-Fi access points).

You will also require to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way.


There are two parts of the requirements for this assignment – a) Report and b) Presentation. Hand drawn layouts for both logical and physical designs are fine. 

The report should be no more than 10 pages and needs to consider the following design tasks:

Design Tasks:

T1. Using the building-block network design process, develop a logical design of the new network for the Victoria headquarter enterprise campus that considers the seven network architecture components. Remember to consider the expected growth of the company. For the logical design, you need to consider the following items:

[25 marks]

  1. Network architecture components
  2. Application systems
  3. Network users
  4. Categorizing network needs
  5. Deliverables

T2. Design the physical design of the network based on the logical design completed in Task T1. Note, you do not need to develop an alternative design. For the physical design, you need to consider the following items:

[20 marks]

  1. Designing client and servers
  2. Designing circuits
  3. Network design tools
  4. Deliverables

T3. Provide a short description of how the LAN of headquarter can be connected with the LANs of the local offices via WAN.

T4. Briefly describe how you will minimise the interference from Wi-Fi access points (APs) on different floors

T5. You will make some assumptions; therefore, document your assumptions and explain why you have designed the network in this way.

You need to produce a presentation consisting of eight PowerPoint slides based on your report and the relevant assessment criteria. The presentation time is 10 minutes. The presentation will be given in Week 12's timetabled tutorial.

Online students can provide the presentations through either an appropriate online video conferencing technique (e.g., Teams) or adding voice-over to their PowerPoint presentation slides.
