Extracts from these regulations are printed overleaf. Please sign below to say that you have read and understand these extracts: Extracts from University Regulations on Cheating, Plagiarism and Collusion Section 2.3: “The following broad types of offence can be identified and are provided as indicative examples ….. (i) Cheating: including taking unauthorised material into an examination; consulting unauthorised material outside the examination hall during the examination; obtaining an unseen examination paper in advance of the examination; copying from another examinee; using an unauthorised calculator during the examination or storing unauthorised material in the memory of a programmable calculator which is taken into the examination; copying coursework. (ii) Falsifying data in experimental results. (iii)Personation, where a substitute takes an examination or test on behalf of the candidate. Both candidate and substitute may be guilty of an offence under these Regulations. (iv)Bribery or attempted bribery of a person thought to have some influence on the candidate’s assessment. (v) Collusion to present joint work as the work solely of one individual. (vi)Plagiarism, where the work or ideas of another are presented as the candidate’s own. (vii)Other conduct calculated to secure an advantage on assessment. (viii)Assisting in any of the above. Some notes on what this means for students: 1. Copying another student’s work is an offence, whether from a copy on paper or from a computer file, and in whatever form the intellectual property being copied takes, including text, mathematical notation and computer programs. 2. Taking extracts from published sources without attribution is an offence. To quote ideas, sometimes using extracts, is generally to be encouraged. Quoting ideas is achieved by stating an author’s argument and attributing it, perhaps by quoting, immediately in the text, his or her name and year of publication, e.g. ” e = mc2 (Einstein 1905)”. A reference section at the end of your work should then list all such references in alphabetical order of authors’ surnames. (There are variations on this referencing system which your tutors may prefer you to use.) If you wish to quote a paragraph or so from published work then indent the quotation on both left and right margins, using an italic font where practicable, and introduce the quotation with an attribution. Further information in relation to the existing London Metropolitan University regulations concerning plagiarism can be obtained from http://www.londonmet.ac.uk/academic-regulations Your tasks are twofold: 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 OSI model and its layers (Session layer and Transport layer). Filename: report12345678.doc You are required to submit three files: 1. the simulation file for the WAN cloud model. 2. the simulation file for the Point to Point links model. 3. the research report on OSI model, technical issues of the Session layer and Transport Layer. Please Note: The filenames must follow the convention described above, and use your own ID number to replace “12345678”. ALL 3 files must be submitted to WebLearn before the deadline, which is declared in the face page of this coursework specification. Further requirement details about coursework 1 are given in the following two sections: Task A and Task B. Task A – Network Simulation Models/Simulations (50% of the CWK in total) 1. Task Description In this section, you are required to model a WAN using the COMNET III software. The assignment requires you to connect Bath city subnet, Watford city subnet and Oxford city 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 Here is the requirement for creating the models: 1. Use three processing nodes per subnet. 2. Use two NetVideo message sources per subnet. 3. Use two types of LANs in the subnets, Ethernet standards and FDDI Basic. • Bath: CSMA/CD • Watford: FDDI Basic • Oxford: CSMA/CD 4. For Packet Size and Probabilities, use 17 rows only. 5. For Packet Interarrival Times and Probabilities, use 21 rows only. 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). 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 8. Run (simulate) the network using a simulation time of any number between 180 seconds to 220 seconds and a warmth length of about 20 seconds. 3.

Each screen copy should have a short description/title. 1. Task Description Write a technical report abou
t Session layer and Transport 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 briefly describe the general technical content for the OSI model, especially present and explain technical in depth looking at main issues about operations of Session layer and Transport layer, 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 assessed, based on the criteria of quality of communication/expression and overall structure – organisation of material, references 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 page numbers.} • 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, then more efforts on Session Layer and Transport layer detailing theirs main issues concerned, figures/diagrams to illustrate, etc.} • Conclusions {condensed version of body; briefly gives key findings.} • References (Bibliography) {demonstration of your referencing skills.} 3.
