THE SCENARIO
The Advanced Digital Computer Company is a new company with its Head Quarters building in the city, and with branches in Parramatta, Hornsby and Sutherland. In addition there are two small home offices in Bankstown and Epping. There are WAN connections between each site and Head Office, with all Internet access through the Head Office site.
The Advanced Digital Computer Company is a retail company for all types of computing devices. The company is planning a restructuring of its network to allow for an expected 100% expansion over the next 5 years. Whilst the numbers of sites are expected to remain the same, the number of employees, and so end computing devices, is expected to double. However, the server farm, currently 4 servers, is expected to be adequate for the foreseeable future.
The Advanced Digital Computer Company has consulted your group to provide a detailed Networking Plan. To assist you the below diagram is supplied.
You must design the network requirements for the Advanced Digital Computer Company. As the network consultant you will be required to develop a plan for the Company network, including all costs, for all of the following:
1. The type of media you propose to use. This must be adequate to allow for a 100% expansion of the Company network within 5 years, and must be sufficient for all bandwidth requirements for each Company site. It should also be sufficient for increased bandwidth needs in the future. Whilst the actual lengths of media chosen are not required, the cost of media chosen should be included as a cost per meter price. You must justify your choice of media. Remember this might include copper, fiber and wireless options. The serial links between each site will be supplied by the company’s ISP and are therefore not to be included in the above media requirements.
2. You are required to subnet the Company’s network IPv4 Address using VLSM as appropriate. You will be required to provide summary tables with IP Address ranges for all hosts in your network. When allocating addresses you must allow enough addresses for the 100% expected future expansion of hosts for the Advanced Digital Computer Company. As well, you need to allocate one (1) printer for each 50 computers (or part thereof) on each subnet. If there are, for example, 70 computers required on a subnet, then two printers are required for that subnet. Printers will have the last usable address/es for the subnet to which they belong. The servers will be located in a separate subnet, and must be allocated static IPv4 Addresses within that network. The number of servers is not expected to grow.
3. The ADC Company is anticipating a move to IPv6 in the future, and so needs to use a Dual Stack environment for IPv4 and IPv6 addresses. You are required to address the network for IPv6.
4. You must detail the hardware (ONLY switches, routers) that the ADC Company will require. This must include full reasons for selecting particular hardware, which must be adequate for the ADC Company’s requirements. Again, consideration must be made with regard to future expansion and bandwidth requirements. The details about computers, servers and printers are not required.
5. You must justify the type of network topology you propose to use at each ADC Company location. A topology diagram for each location should be included in your report.
6. Communication on the Internet is essential. Select and fully justify the type of Internet access you propose to have for this Company. This must be scalable to allow for future growth and needs. The Point of Presence (POP) is located at Head Office.
