Assignment Description

Outfit is a well renowned fashion retail company. The company’s head office is located in the Melbourne CBD. The head office consists of three departments: general support, marketing, and sales. General support is located on the first floor, while the marketing and the sales departments are located on second and third floors of the building respectively. General support has 12 workstations, marketing has 15 workstations, and sales has 20 workstations. Some applications require that data be shared between departments, but generally, each department has its own applications. Every workstation needs access to the Internet, the company internal Internet (intranet), and e-mail. Each floor has a printer connected on the network. The head office also requires wireless internet connectivity for all the floors.

The company is also planning to establish five offices in Brisbane, Adelaide, Sydney, Canberra, and Darwin. According to the specifications provided, the most user resource requirements will be met by servers located in the same office as the users who need to access them. The main communication requirements between offices relate to print jobs, e-mails and periodic file transfers.

Suppose you are hired as the network engineer of the company to design the network for the head office. The area manager of the company has asked you to prepare a networking solution that enables employees in all five offices to communicate both internally in that office and, to a lesser extent, between the other offices and head office. The network design incorporates both wired and wireless networks.

Write a report with following sections:

  1. Introduction
  2. The LAN network design of the head office
    1. With help of a suitable diagram, identify and discuss the locations of all workstations and interconnecting devices, such as switches, routers, wireless access points (APs) etc.
    2. Discuss the LAN topology and relevant protocols. Recommended media type to be used for both wired and wireless communication
    3. Identify and discuss the connection that provides the Internet access to the head office network
    4. Report the role of Network operating System (NOS) in a LAN environment. Recommend a NOS suitable for the company.
  3. The WAN network design between all five offices and the head office
    1. The sketch of the WAN connectivity and discuss the devices to be used such as routers (if any) and their functioning
    2. Discuss the media type used to connect all offices to the head office
    3. Report the type of network structure suitable in this scenario (circuit switched or packet switched structure). Which connection among synchronous, asynchronous and isyncnronous is suitable in the scenario? Justify your recommendation.
    4. Discuss the recommended routing protocol in this scenario
  4. A summary section
  5. References
