Information Systems Networking Essentials


The Advanced Digital Computer Company is a new company with its Headquarters 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.

Advanced Digital Computer Company Network Plan


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.

IPv4 Addressing

The Advanced Digital Computer Company has purchased the IP Address (Given by your Instructor) from its ISP for addressing all hosts within its network. Subnet, using VLSM, this IP Address to provide addresses for all required hosts. This addressing scheme should allow for the 100% expected growth. Complete the table below.

IPv6 Addressing

The Advanced Digital Computer Company has purchased the IPv6 Address (Given by your Instructor) from its ISP for addressing all hosts within its network. Subnet, using VLSM, this IP Address to provide addresses for all required hosts. This addressing scheme should allow for the 100% expected growth. Complete the table below.

Additional Information

1.   Apart from the IP Addresses, you are not required to supply any WAN link information. This included serial cables, VPN connections, or any security issues relating to those links.

2. Head Office employees are in three separate networks as follows:

a. Sales 60 Hosts

b. Marketing 35 hosts
c. Accounts 30 Hosts

3. There will be a Server Network, with 4 Servers, for the entire Company. This will be situated in a separate LAN in the Head Office building. It is expected that the 4 servers will be sufficient for the next 5 years, and so will not be subject to the 100% growth requirement.

4.  All branch offices and Home Offices can be considered an extension of the Head Office network, and so the IP Addresses allocated must be reflected in the overall addressing scheme for the company. The only media requirements required are those internal for each site.

5. Hardware (such as routers and switches) should reflect expected usage. Therefore, low usage environments such as those for the Home Offices, would require different hardware than high usage areas, such as those of the Head Office.

6. Internet Access for the entire company, the Point of Presence (POP), is through the Head Office. This connection should be sufficient for all current users, and scalable to allow for the expected increase over the next 5 years.


This assignment is to be done in a group. Much of the work can be based on research carried out on the Internet. All information obtained must be fully referenced using the referencing method, as per the subject outline.

The assignment is due on Friday (01/02/19). Late assignments will incur a penalty of 5% per day, as per the subject outline.

This case study will assess all objectives from the course outline.

There is no minimum mark required for this Assignment. Students who fail to attain 50% for it will need to work harder in other assessment items to make up the deficit.

The Case Study must have a title page with the following information: Course Name Information Systems Networking Essentials Course Number ISY202/ISY2002
Case Study Title Assignment 1

Case Study due date Week 10, 1st February 2019 Word Count – 2000 - 2500

DO NOT include copies of referenced material or other documents (such as pamphlets) with this assignment. However, proper referencing of all sources is essential. Referencing should follow the style as per the subject outline.


This Assignment is marked out of 100 marks and is worth 20 percent (20%) of the overall assessment. The length of the report for this case study should be a maximum of 2500 words. Diagrams, tables and figures can be an addition to this length. Text should be formatting as 10pt/11pt A4 with double line spacing or 12pt with single line spacing. Remember, this assignment will be written as a report. Marks for this assignment will be allocated as follows:
