Introduction
This case study has been divided into four components.
You are to design a network, research and source appropriate devices justifying choices (feasibility, efficiency, etc.), subnet the network, assign IP addresses to the appropriate devices, and write a report introduction for the project.

Note: This is not a group project. Each student must individually complete all parts of their submission.
Students must start with a new document and they must not have another person’s file in their possession at any time. Students may discuss the task with each other, but each student must write their assignment independently and not show their work to other students.
Deliverables
A single Word document (.docx) – containing all parts
Assignment breakdown
Scenario
Ausdata Services Inc., an Australian data analytics company, has asked you to assess and redesign their network. They are opening a new branch in Mackay, which will require new equipment. They have existing contracts and hardware to maintain fibre-optic leased line WAN links between sites.
PART 1 – Introduction
PART 2 – Network diagram
PART 3 – Subnet the network and assign IP addresses to the appropriate devices
PART 4 – Research and source appropriate devices justifying choices (feasibility, efficiency, etc.) with a Weighted Scoring Model (WSM)

PART 1 – Introduction
The first part of your report should be introduction to the project. Although this is the first part you should include in your report, it should be the last part that you write. In your introduction you are to provide an outline for each of parts 2, 3, and 4.
What to include:
Describe the overall task of assessing and redesigning the network.
Explain why it is important to produce a well-designed network diagram.
Explain why it is necessary to create and document the separate subnets for the network.
Explain why new equipment is needed for the new branches, the basic role of the switches and routers, and the process you used to select the equipment.
The introduction should be well-articulated: clear, concise, and use correct spelling and grammar. The intended audience for the introduction can be assumed to have basic technical knowledge but are not networking experts. The introduction should be no longer than a page.
PART 2 – Network specifications and diagram
Network Specifications
You have been given a rough sketch of the network topology below. You are to draw the network using Visio, subnet the network (see part 3), and assign port numbers and IP addresses to ports.
Network Structure
Hardware
Only include one switch in you diagram for each LAN or WLAN (even if more are required)
Servers should be on their own LAN
The Internet router port address is 31.255.14.98/30
The Gosford router is connected to the Internet and provides access to the public backbone containing a web server and a compute server.

PART 3 – Subnet the network using VLSM, and assign IP addresses to the appropriate devices.
Each location has the following number of hosts
Gosford, Canberra, Cairns, and Mackay each include a wireless LAN for clients to use.
Location
Workstations
WLAN addresses

Gosford
600
120

Canberra
300
30

Cairns
150
14

Mackay
80
14

Darwin
60

Adelaide
40

Subnetting
Use VLSM to subnet the network topology using a public class B network. You are to use the table format below to provide the subnet details.
Table 1. Subnets (including WAN subnets)
Spreadsheet Columns: Subnet name, subnet address, subnet mask (in slash format), first useable address, last useable address, broadcast address, static address range and DHCP address range (all addresses to be in dotted decimal notation)
Table 2. Router Interfaces
Spreadsheet Columns: Location, interface, IP address, subnet mask (in slash format)
Table 3. Servers
Spreadsheet Columns: Location, server name, IP address, subnet mask (in slash format)
Additional requirements:
Choose one public B class network address for the entire network and subnet this block of addresses to optimise spare addresses for future expansion.
Place the WAN subnets in the blocks directly following the LAN address space.
Add 100% to each subnet to allow for growth in the number of hosts specified for each LAN (i.e. workstations × 2). Do not allow for any growth in the number of servers or size of WLANs
DHCP will to be used for IP address allocation for hosts in each subnet and these ranges are to be allocated for each LAN.
Static IP addresses are to be allocated where appropriate.
The ISP has given us an IP address of 31.255.14.98/30 for our Internet connection at Gosford.

PART 4 – Research and source appropriate devices justifying choices (feasibility, efficiency, etc.)
You are to research and submit a project procurement plan for the Mackay network. The devices you must include are routers, switches, and wireless access points. Make sure the devices you select can handle the number of workstations required and provide a good quality of service to wired and wireless users.
Your project plan and final recommendations should be based on a Weighted Decision Matrix (like the WDM you did in the Procurement Practical). You are to compare five (5) devices from each category and to base the decision on reasonable and well-justified attributes.
The budget for procurement is $7,500. You may exceed this if you can justify it well.
Your project plan is to contain the following components:
Weighted Decision Matrix – hardware resource requirements analysis
Include a written justification for priorities and attributes given in the matrix
Create your WDMs in Excel and copy and paste them into your Word doc
Budget
Create a well-presented table of the prices of all devices and the total cost
Include hardware only, not labour

Marking Scheme
