Global Network Architecture - Research Paper Example

Berlin to Beijing is the weakest link. In the event of failure it completely cuts off links between east and west. Furthermore, it has the lowest bandwidth which means even in the absence of such an event, data flow is still slow. The next two are Beijing to Shanghai and Singapore, the bandwidth is low and in the event of disruption each endpoint city could be completely isolated from the rest of the network. We suggest how the network could be re-designed to overcome the weaknesses and vulnerabilities identified.

If the company can only afford to make ONE of the changes you propose, recommend what that change should be, we recommend add a Cairo to Singapore link at 512Kbps. It would lighten the load on the weakest link as well as allow redundancy in the east-west backbone. In order to provide global communications, fiber optic cables need to be laid under the oceans of the world. We have provided details of a modern day, and currently operational, cable laying ship; including its name, technical specification in terms of its cable laying capability, what techniques it uses to lay cables and examples of a recent mission: This vessel has worked along with the Asia-America Gateway. . vided details of a modern day, and currently operational, cable laying ship; including its name, technical specification in terms of its cable laying capability, what techniques it uses to lay cables and examples of a recent mission:Cable ship NiwaFlag UAEPort of registry Abu DhabiCall Sign A6E 2964Shipbuilder Far East Levingston Shipbuilding Ltd.
