ITC542 Internetworking with TCP/IP - Charles Sturt University

Task

This assessment aims to develop and gauge student understanding of the key topics covered so far by answering the following questions. Answering these questions will help you build some understanding for the next assessment item as well as for the entire subject. It is expected that answers to the assignment questions be succinct (i.e. precise and concise) with all sources of information fully referenced as per APA referencing style. You have to reference the text book and any additional material you have used in your answers.

Note that the guide for APA referencing is provided in the resources section of Interact site of this subject.

Answers MUST be written in your own words. No marks will be awarded for any answer that contains more than 10% direct quote (referenced or unreferenced). One or two sentence answers will be too short and only receive low marks. Answers longer than 1.5 pages (12 point font, single line spacing) may incur a penalty if too much non-relevant information is stated. For mathematical questions it is expected that you show intermediate steps of your working. Just stating the correct solution will result in low marks, on the other hand if the working is correct and you only made minor mistakes, you will still be awarded marks, even though the final answer is wrong.

Question 1
Complete the Hands-On Projects 3-1 and 3-2 from the prescribed textbook (pg. 144-145). The files required to complete these projects are available from the "resources" folder in the subject site. In order to complete these activities, students should insert screenshots in the assignment document along with a brief informative description of each step taken to complete the project. Marks will be deducted if the description is not provided.

Question 2
Watch the following two videos and write a reflective piece based on your observations and insights on the workings of both Link State and Distance Vector Routing, highlighting the major differences. In addition to the videos, students are encouraged to consult authentic additional resources such as text book, research articles etc. to enhance understanding of the topics.

Question 3 Case study task

Let us consider three hosts connected together in a local network having private IP addresses 10.0.1.14, 10.0.1.15 and 10.0.1.20. Between this local network of three hosts and the rest of the internet is a NAT enabled switch/router as shown in Figure1 below. All information in the form of IP datagrams being sent from or incoming towards these hosts must pass through this device.

Task 1
Figure 1 above shows a switched network, with Host A, B and C connected to ports Fa0/1, Fa0/2 and Fa0/3 respectively; the current MAC address table of Switch-1 is empty as below:
Mac Address Port Number

a) Discuss what would happen next if Switch-1 received a frame from Host-A with the destination MAC address of host-B?
b) Discuss what would happen next if Switch-1 received a frame from Host-B with the destination MAC address of host-A?
In both cases, illustrate the changes in the MAC address table in your answer.

Task 2
Let us assume that the host with IP address 10.0.1.20 sends an IP data-gram destined to host 128.119.165.183. The source port is randomly selected as 3428, and the destination port as 80.
What are the source and destination addresses of the IP datagram as well as the source and destination port numbers for the TCP segment in the datagram at:
a) step one (i.e. after it has been sent from the host but before it reaches the router).
b) step two? (i.e. after it has been transmitted from the router).
c) step three (just before it is received by the router)
d) step four (after it has been transmitted by the router but before it is received by the host).
