Part A: Design Scenario (70 points)
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.
Head Office employees are in three separate networks as follows:
a. Sales 60 Hosts
b. Marketing 35 hosts
c. Accounts 30 Hosts
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. 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. Use network address 188.8.131.52/22 for subnetting. Complete the Table on the next page accordingly.
