Unit 9: Communication Technology Assignment 9.1: County Colleges Network Scenario There are five colleges in a county area interested to be connected into a WAN. This will enable them to: •Communicate with each other using videoconferencing, email etc •Specify access to each others Web site to enable the sharing of teaching materials using Powerpoint, multimedia, video/audio etc. Students should be unaware of whether they are connected to their local or another college. They should be able to access the WAN from home as well as at the college. One college is to implement a LAN to: • Connect all staff machines which are currently standalone in 15 different staff rooms spread across 3 buildings which are no more than 100 metres apart. • Connect four different student resource rooms: 2 are 10Mbps Ethernet, one is 100Mbps Ethernet and one is not networked. • Provide an intranet for students and staff to use. • Give students access to the Internet using a local HE provider's JANET system. • Develop a Web site to advertise courses, provide enrolment and teaching materials, for assessment and to gather feedback. The aim is to produce a communications strategy and specification for the WAN and LAN outlined above. Task 1: College managers have had experience of video conferencing and want to implement it between the five colleges for regular meetings. These are primarily discussions but may include viewing charts such as individual timetables. Video Conferencing, of course, requires the transmission of both moving images and voice signals. a) By using the requirements of a standard telephone call and those of conventional moving images displayed on a television screen in terms of the bandwidth required, calculate the apparent requirement of a near perfect video conference link. b) Given that video conferencing was designed to operate over basic rate ISDN links, it is clear that some clever technologies had to be implemented to reduce the amount of data but retain a certain quality. These might be categorised into; • Raw binary compression techniques with the help of mathematicians and their ways of compression • Manipulation of the source sound and image data with the help of biologists and how they understand the response of our senses so that unnecessary data van be removed • Clever assumptions about the actual data in terms of what needs to be transmitted often and what can be transmitted less frequently • The quality of the result that the users need and think that they need in a college environment For each of these categories explain the techniques applied in order to reduce the bandwidth requirement. c) If all the above were applied to an absolute minimum standard, estimate the bandwidth required. d) If improvements on the minimum really had to be made, choose the areas to improve and estimate a realistic bandwidth. In each case quantified estimates are required. e) With a fast Internet connection between the colleges a separate BRI ISDN link may not be necessary. Research current methods of implementing both Voice over IP (VoIP) Multimedia over IP (MoIP) and videoconferencing equivalent facilities over a TCP/IP connection under the following headings:
• Bandwidth required • Companies offering the facility • Type of service offered in terms of quality and additional services such as data Cost Task 2 • Show how the 5 colleges may be linked together and with the Internet. • Show how the following could be arranged: o a LAN configuration of a typical floor o how the floors are connected o connection to the Internet All the above will require money! By breaking the entire network into components parts, find a cost for the complete enterprise. • evaluate the cost network implementation Task 3 Before work begins and money is spent the college will need to prepare a SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis. Take on the role of the college manager in charge of the network project and produce such analysis. In preparing this analysis you need to note the following: • the factors affecting the introduction of communication network • The cost of a major breakdown in the network lasting, say, three days • A college wants to allow students to access the network from home and possibly to allow them ISP facilities. List the hardware and software that would be needed to make this possible in terms of servers and security. • The college has an idea that such a network could be used to produce an income for the college. List various ways in which this could be possible along with rough estimates on the sort of revenue that might accrue. • describe the major threats to a network and measures to protect against them.
