Network Requirement Analysis and Design
Purpose of the assessment

After successful completion of this assignment, students should be able to:
• Apply concepts and theories of human factors as related to network design and implementation
• Compare performance metrics and dimensions according to specifications

Assignment Description

Objectives:

A wholesale business is expanding, they hire you as a network engineer to design and implement their IT infrastructure. It is an assumption that the organisation intends to go with the latest technology however, reasonable budget and expending is highly recommended.

In a face-to face meeting with a manager, you receive general information about the organisation. In the meeting, it is advised to collect the rest of the requirements. The general information is as follows:

There are two sites one in Sydney and other in Melbourne. Sydney site requires 40 employees while Melbourne site have 25 Employees. Both the sites have Customer Services, IT, Sales and Marketing. The Sydney site have two extra Departments i.e. Human Resource and Accounting.

A network design and implementation proposal is required. As a part of proposal, submit a report to address following two tasks.

Task 1:
In order to gather (user, application, and network requirements) different techniques i.e. Interviews and questionnaire are used. Create a questionnaire to get application requirements. The questionnaire must have at least 10 questions. Describe the purposed of each question and categorise the questions whether it is focused to user, application or device requirements. Record possible answers to use in next task.

Task 2:
• Based on the requirements identified at Task1, design a WAN structure of the business showing all devices such as routers, switches, links, etc. by Using a relevant network designing software. Draw a diagram to illustrate your high-level design.
• Determine Network Addresses by using the subnet 192.168.P.0/24, where P is your group number. You also need to use Variable Length Subnet Mask (VLSM) technique whilst creating the subnets and allow 30% for possible future expansion.
• You need to explain the technical aspects for the choosing devices such routers, switches, hubs, Aps, cables, servers etc.
• (Using either Netsim or GNS3 or Packet Tracer) Configure the topology devices with basic configurations, routing and NAT. Extra configuration such as VLAN and Port security entitled to extra marks.
