Wide Area Networking Technologies
London College of Education (LCE) is a Higher Education (HE) institution offering a wide range of academic qualifications to a diverse student population in London, United Kingdom. Their motto is “Education studies Power”. By offering a wide range of academic qualifications to a wider community, they believe that they will empower a generation to make a success of themselves. Due to the recent high demand for higher education worldwide, LCE has decided to expand its operations to include Africa, Eastern Europe, and The Caribbean.
They have recently established new sites (campuses) in Lagos, Nigeria as their African Headquarters, Warsaw, Poland as their Eastern Europe Headquarters, and Kingston, Jamaica as their Caribbean Headquarters together with their main Headquarters in London, United Kingdom. Each location has a fully functioning network with various departments operating each site. All the sites are interconnected by dedicated Routers to enable greater network security, reliability, and performance.
London HQ:
CEO’s Office, HR & Marketing, IT Services, Academic Departments, Registry, Student Services, and IT Labs
Logos HQ; Warsaw HQ; Kingston HQ:
Each has the following; Head of Region, HR & Marketing, IT Services, Academic Departments, Registry, Student Services, and IT Labs
Each location should have the capability to support WAN infrastructure which includes, BUT NOT LIMITED to access to the Internet, PCs, laptops, Tablets, IP telephone, printers, Lab PCs, Staff PCs, and a fully functional IT Room, etc.
Important Issues to consider:
∙Security, reliability, confidentiality, and personal performance are very important to LCE as it manages its own global data network to ensure that data being transmitted over the network is secure.
∙Clients and employees should be able to communicate at a low cost using IP phones. Therefore the network hardware connectivity should be of high standards and current.
∙Since LCE has HQ offices in different locations around the world, LCE wishes to create a private corporate network that is able to connect these sites together and transport traffic of different types (both data and

telephone calls) between them. In order to fully run its operations in all locations, the Management has decided to employ a Network Manager to plan, design, configure, implement and test the Wide Area Networking (WAN) in all sites.
TASK 1 (LO1: 1.1, 1.2 and M1) Interim Deadline (6th October 2014) Word Limit (600-1,000 with diagrams) (Formative Assessment in Week 3)
∙Critically evaluate the following WAN technologies; dial-up, broadband, Frame Relay (FR), ADSL (Asymmetric Digital Subscriber Line), ISDN (Integrated Services Digital Network), MPLS (Multiprotocol Layer Switching), interior routing protocols, exterior routing, static routing, routers, layer 2 aggregators, servers, cabling systems, modems, transceivers, satellite uplinks, 3G, 4G, 5G, and VPN concentrators
∙Critically analyze the following WAN traffic-intensive services and their performance: quality of service management eg DSCP (Differentiated Service Code Point), IP precedence, queues, base rules, congestion management; quality of service need eg Voice over IP, video streaming, and audio streaming
∙Critically evaluate the importance of Quality of Service (QoS) in network design with particular reference to VoIP, video streaming, and audio streaming.
HINT:
Your answer should include detailed explanations of each of the above with relevant diagrams to support your explanations.
