Data Communication

This assignment is designed to help you develop skills and strengthen your understanding of data communications.

The scenario

Your client is a small, but rapidly growing travel agency. They presently have an office in the Sydney Central Business District (CBD), a small site office located near the airport in Mascot, and a Data center located in Macquarie Park. They plan to shortly open three more offices located in the major Sydney suburbs of Parramatta, Chatswood, and Hurstville. Each of these offices will have an identical structure to the Sydney CBD office.

A diagram showing the network topology of your client's network is shown in Appendix A, with MAC addresses for each device provided in the table that follows in Appendix B.

Question 1 - Data-Link Layer
a. Some of the switches are marked as "managed", whereas some are marked as "unmanaged". Briefly describe the difference between these two kinds of switches.

b. What impact does the use of managed or unmanaged switches have on addressing within the network?

c. Identify the manufacturer of each device using the information provided in Appendix B. Your answer should include a brief description of how you determined the manufacturer (don't forget to including any necessary scholarly references and citations).

d. What speed will each of the links between devices operate at (refer to Appendix A)?

Question 2 Subnetting
Your service provider has given you the 192.168.23.0/25 network. Devise a Variable Length Subnetting (VLSM) scheme to accommodate the network (including the planned suburban Parramatta, Chatswood, and Hurstville offices). Each subnet should include the network address, broadcast address, the maximum number of hosts supported by the network, and the netmask in dottted-decimal notation. Please ensure that you document each step of this process.

Question 3 Encapsulation and network traversal

a. A user logged into PC1 in the Sydney CBD office on PC1 opens a command prompt and uses the ping command to test connectivity to Printer2 located at the Mascot site.

Explain what traffic this command will create, both directly and indirectly, and how this traffic will affect the caches and tables within each device.

In your answer, you should assume that the caches and tables in each device are empty before the ping command is run.

For example, if you had a HTTP request originating from HostA with MAC address 46:2D:C0:93:42:AD, and IP address 172.16.3.2, and destined to HostB with MAC address 97:22:51:67:B5:88 and IP address 172.16.3.5, then you could notate the packet as it leaves HostA as follows (note that we don't know enough detail about Layer 5 to say anything other than "HTTP request"):

[Ethernet SRC: 46:2D:C0:93:42:AD, DST: 97:22:51:67:B5:88 [IP SRC: 172.16.3.2, DST: 172.16.3.5 [TCP SRC: 49238, DST: 80 [HTTP request]]]

b. There are two possible paths that this traffic could take, via WAN1 or via WAN2. Provide a brief explanation of which path will be taken and why.
