3 SUBJECT : NETWORK SYSTEMS III SUBJECT CODE : NETS 301 PRE-REQUISITES : Digital Communication II, Network Systems II DURATION : The course extends over one semester (90 hours) or 14 weeks. CONTACT TIME : The subject is presented each week in two parts: (i) 2 theory lectures and 2 laboratory periods and / or tutorial periods TEXT BOOKS Prescribed: Fred Halsall, Computer Networking and the Internet, 5 th Edition, Addison Wesley, 2005 Recommended: Data and Computer Communications, 8 th ed., William Stallings, Pearson Prentice Hall, 2007 Computer Networks, 4 th ed., Andrew Tanenbaum, Prentice Hall, 2003 Computer Networks: A Systems Approach, 3 rd ed., L Peterson & B S Davie, Morgan Kaufmann, 2003 Networking, 2 nd ed., Jeffrey Beasley, Prentice Hall, 2009 METHOD OF ASSESMENT: The FINAL MARK of this subject is arrived at by the combination of the following: (i) 60 % (Theory) 15 % Class Test 1 15 % Class Test 2 15 % Class Test 3 15 % Class Test 4 30% (Practical) 15 % Practical Test 1 15 % Practical Test 2 10% (Assignment) 10 % Assignment Make-up Test (covers entire syllabus) For students who achieve 45 to 49% determined from the weighting outlined above provided a minimum of 40% is achieved for both practical tests. If a student achieves a mark that is more than 50% in the make-up test s/he will be allocated a maximum mark of 50%. This new mark will then replace the lowest mark achieved in one of the tests written and the corresponding weight used to of the tests written and the corresponding weight used to calculate his/her final mark.

4 NOTE: (i) A pass will be a final combined total mark of 50 % or more. A total mark of less than the minimum of 50 % will result in a fail. PURPOSE: The purpose of this subject is to build on the subject matter covered in: Digital Communications II - which covered the Physical and Data Link Layers. Network Systems II - which covered the Network Layer. This subject will take the learner further, covering the final layers, Transport and Application Layers. Basic principles will be emphasised and topics of fundamental importance concerning the technology and architecture of these layers for data and computer communications will be covered. The subject explores the key topics in the field of data and computer communications in the following general categories: Transport Layer : Address/Name resolution, Addressing methods, Segment development, Connection services, and End-to-end flow control. Application Layer : Dialog control, Session administration, Translation and Encryption, Service advertisement and Service use Methods. In general, a building-block approach will be taken. The principles of data communications will be carefully and thoroughly explored. These principles will then be applied to the complex systems found in communication networks and computer-communications architectures. PRACTICAL WORK: The course practical work is based on the Cisco Certified Network Associate (CCNA) concept and uses the Cisco Packet Tracer software. As a learning procedure, to relate theory and practical usages of connectivity, configuration of Router (Rip, Access-List (Standard Access List, Extended Access List)), Server Configuration is given importance. CONTINUOUS ASSESSMENT AND LEARNING OUTCOMES: Continuous assessment means that your effort and level of competence is continually being assessed. Formative assessments are on-going in all lectures, practical and tutorial classes by means of verbal and written questions, class exercises and tutorial problems. These assessments are meant to guide you in self-assessing your knowledge and competence. The tests are both formative and summative assessments. Use the table below to guide you in understanding what the assessment criteria are and their relative weighting for this subject. Page -4-

5 LEARNING OUTCOME ASSESSMENT CRITERIA ASSESSMENT METHODS Comprehension (30%) Correct understanding of Written/verbal technical text. Correct understanding of Technical diagrams. Test, tutorial and practical questions. Application (30%) Analysis (20%) Best practice construction of software scripts. Best practice written reporting. Best practice construction of technical diagrams. Best practice method and correct result of calculation or determination of technical details of techniques, circuits, Systems and scripting software. Synthesis (20%) Best practice method of problem solving. Best practice documentation of objectives, method and results. Practical exercises. Practical report writing. Test, tutorial and practical questions. Tests and practical exercises. Practical report writing. Comprehension and analysis are the major components of the expected learning outcomes. Comprehension involves understanding and integration of information. That is, can you see how the pieces of information fit together? Can you translate the information into different contexts? Analysis requires comprehension as a pre-requisite. Analysis is very important in technical fields. Successful analysis requires careful attention to detail which means checking your facts and working. At level 3 you are also expected to be able to apply your knowledge of the subject material by following methodical analysis and synthesis using relevant theory to arrive at a suitable solution to a complex problem. Best practice documentation of objectives, method and results is critically important. Page -5-
