Task:

Tasks for the individual coursework 1:
 
Task A: To produce two network simulation files (WAN cloud model and Point to Point links model).
Filenames: wan12345678.c3 for WAN cloud model, and p2p12345678.c3 for the Point To Point links model. (the extension name “.c3” will be automatically created by the COMNET III)
 
Task B: Carry out your own research to produce a technical report on Network layer and Data Link layer in OSI model. Further requirement details about the report are mentioned in Task B section.
Filename: report12345678.doc
 
You are required to submit four files:
1. The simulation file for the WAN cloud model
2. The simulation file for the Point to Point links model
3. Video presentation - to demonstrate how your implemented models work
4. The technical report on Network layer and Data Link layer in OSI model.
 
Please Note: The filenames must follow the convention described above, and use your own ID number to replace “12345678”;
 
All the four files must be submitted onto WebLearn before the deadline, which is declared in the face page of this coursework specification.
 
Task A - Network Simulation Models/Simulations
(50% of the CWK in total)
1. Task Description
 
The assignment requires you to model a WAN using the COMNET III software. The assignment requires you to connect the Chester subnet, Oxford subnet and Plymouth subnet using (a) a WAN cloud; and (b) Point To Point links. The assignment intends to make use of Bus LAN, Token ring LAN, subnets, the WAN cloud, Network Devices and Point To Point links, and the routing protocols.
 
You need to set up the structure of a network to support the various operations and in particular video conferencing using the multicast backbone. Part of the work also includes answering some technical questions.
 
This assignment is based on chapter 8, “Modeling Wide Area Networks”, in pages 36 to 56 (inclusive) from the PDF file available from the section Learning Materials of the WebLearn (filename: Comnet_CH7-8.pdf). The following changes to the models, however, are made, which are described as follows.
 
 
 
 
 
 
2. Model the WAN using both WAN cloud, and Network Devices and Point To Point links with proper routing
 
Requirement for creating the models
 
1. Use three processing nodes per subnet.?? ??   ?(3 Marks)
2. Use two NetVideo message sources per subnet. ????(2 Marks)
3. Use two types of LANs in the subnets, Ethernet standards and FDDI Basic.
????(6 Marks)
• Chester: Ethernet standards
• Oxford: FDDI Basic
• Plymouth: Ethernet standards
4. For Packet Size and Probabilities, use 14 rows only. ??   ?(4 Marks)
5. For Packet Interarrival Times and Probabilities, use 19 rows only.  ?(4 Marks)
6. Model the Wide Area Network using WAN cloud (its filename starts with “wan” plus your student ID number) and using Network Devices and Point To Point links (its filename starts with “p2p” plus your student ID number). ?  ?   ?(6 Marks)
7. Insert your surname, first name and student ID in the first windows of your WAN cloud and Point To Point links. Position your name and ID at the top left corner. ???????  ??   ??(4 Marks)
8. Run (simulate) the network using a simulation time of any number between 220 seconds to 260 seconds and a warmth length of about 30 seconds. ?(6 Marks)
9. Video presentation to show how the developed models work and their accuracy????????????(15 marks)

End of Task A
Task B - Technical Report (50% of the CWK in total)
 
In the end of this report, screen copies of your developed models and simulation result of Task A MUST be presented.
 
Each screen copy should have a short description/title.
 
1. Task Description
Write a technical report about Network layer and Data Link layer in the Open System Interconnection (OSI) model, which should be the culmination of good literature search work carried out through using a good mix of sources: Book, journals, industry white papers, research outputs of organisations, web resources that have provenance, and textbooks.
 
It should describe the general technical content for the OSI model, especially present and explain technical in depth looking at the issues about operations of Data Link (MAC and LLC) and Network Layers, etc. This technical report should not exceed 2000 words in length (excluding Cover page, Contents page and References).
 
The report structure and quality will also be marked, based on the criteria of quality of communication/expression and overall structure – organisation of material and quality of documentation.
 
2. A recommended report structure is shown below for your reference
• Cover Page  {clear and concise- e.g. Task B: Technical Report, Module Code, Module Title, your name and student ID number}
• Contents Page  {shows structure of report - section numbers, heading and pages}
• Introduction  {very brief description of aims (general) and objectives (what is done to achieve the aims to put report within context/sets the scene for the reader (e.g. where does this development fit within the field)}
• Body of report  {main part of the report; e.g. briefly describe the structure of the OSI model, especially on the technical issues of Data Link layer and Network layer concerned. }
• Conclusions {condensed version of body; briefly gives key findings to reflect your understanding}
• References (Bibliography) {demonstration of your referencing skills}
• Appendix: screen copies of your developed models and simulation result of Task A. Each screen copy should have a short description/title.
