A Comparision of Switching Techniques: In the Interconnection Networks

Nowadays systems have became more complex and faults can have more influence on them. There are some cases where we can not monitor or repair, like satellites. Also some systems have a crucial role and they can not fail at all. So however our components are fault tolerant but more fault tolerance is needed. On the other hand, the processing power has increased and the interconnection network between them has became the bottleneck. In this paper we study some switching techniques in the interconnection networks. Then an improved switching technique is proposed. Our proposed technique tries to provide more fault tolerance while keeping performance too. finally, this techniques are compared.
