Performance studies of routing schemes for packet switched augmented shuffle exchange network

This paper presents a simulation study to compare the performance of four different routing schemes for a internally buffered packet switched fault-tolerant augmented shuffle exchange network. The performance is measured in terms of throughput and delay for uniform and non-uniform traffic patterns under fault-free and faulty environments. The simulation results indicate that the "look ahead" scheme proposed by Peir and Lee (1993) provides the best throughput at a minimum delay under non-uniform traffic with and without faults.
