Performance studies of packet switched augmented shuffle exchange networks

Extends previous research efforts related to the performance modeling of the fault-tolerant Augmented Shuffle Exchange Network (ASEN). The authors examine the ASEN run-time performance characteristics in a packet switched environment. The network performance is examined under a fault-free but congested network operating environment. Network performance parameters of time-in-system, queue lengths and delays, as well as the effects of non-uniform loading of the network are presented. The cost associated with implementation of an ASEN is compared with previously published metrics for the multistage cube network operating under the same environments. The authors conclude that, for the network and operating assumptions defined, the ASEN provides better performance at lower implementation costs than the multistage cube interconnection network.<
