Operating System and webing - Coursework Examplethe primary factor that great deal be examined is the Wide Area Network. Likewise, if the college is communicating with the remote offices concludes that a proper Wide Area Network connectivity is present. However, there are many WAN technologies that can be positioned to cover all the specified requirements. Moreover, debauch computing has also gained a high value and is well recognized in academic institutions in the UK, as researchers share information on a collaborative platform. For instance, University of Portsmouth has already initiated a commercial social occasion of off the shelf cloud service from globally recognized organizations such as Google and Microsoft (Cloud guarantees bright chance 2012). Equally, cloud computing saves significant cost and the complex Information Technology acquisition procedures and processes (Cloud guarantees bright chance 2012). The University is synchronized with the other three remote camp uses and 5 other campuses that are located outside the city. Likewise, a robust WAN infrastructure is required to fulfill these long distance connectivity and data transfer requirements. As mentioned earlier, the different WAN technologies that can be implemented in this scenario are Point to Point Connectivity locomote Switching portion Switching WAN Virtual Circuits WAN Dial up Services We cannot deploy point to point connectivity, as it provides a dedicated link from the customer premises to the carrier earnings. As the University is connected to multiple locations, several point to point links are required, resulting in a pricey solution. Secondly, circuit switching also resembles with the point to point connectivity technology and it is comparatively tiresomeer. One example of this technology is Integrated Services Digital Networks (ISDN). Thirdly, WAN dial up services are also associated with slow and outdated technology. Moreover, virtual circuits will not be efficient in a crisis situation, as it cannot do by a lot of traffic and if the device stops working, the whole connection is lost. Finally, WAN virtual circuits and Packet switching technology will be considered in this scenario. Packet switching WAN technology shares a single point to point connectivity within network devices to exchange data from source to destination via a carrier network. Moreover, statistical multiplexing techniques are implemented to activate software system switching in network devices. well-nigh of the examples of this technology are Asynchronous Transfer Mode (ATM), Frame Relay etc. Advantages after deploying packet switching technology within the University are demonstrated below As the data packet breaks into humble data chunks, bandwidth capacity utilization is optimal Confidentiality, Integrity and Availibility is addressed, as the confidential data needs comely security Compatible with devices supporting different transfer rates, as end users or network de vices set up at different remote campuses may support different transfer rates. In case of a link failure, signals are re routed by using a different path ensuring high network availability. In case of a declared disaster or a failure of a phone exchange, end users can still send emails for service interruption notifications and vice versa. Above mentioned advantages concludes that
