抜粋

Multistage Interconnection Networks (MIN) with multiple outlets are networks which can support higher bandwidth than those of nonblocking networks by passing multiple packets to the same destination. Fault recovery mechanisms are proposed for two of such networks (TBSF/PBSF) with the best use of their inherent fault tolerant capability. With these mechanisms, on-the-fly fault recovery is possible for multiple faults on switching elements. For the link fault, the networks are reconfigured after fault diagnosis, and the network is available with some performance degradation. The bandwidth degradation under multiple faults on link/element is analyzed with both theoretical models and simulation. Through the analysis, F-PBSF shows high fault tolerance under high traffic load and low reliability by using 3 or more banyan networks.
