Abstract

Designing a reliable and high performance multistage interconnection network (MIN) should consider the following issues carefully: (1) fault tolerance guarantee; (2) easy schemes and hardware design of rerouting switches; (3) low rerouting resulting in a low collision ratio. In this paper, we present the High Performance Chained Multistage Interconnection Network (HPCMIN) which has one-fault tolerance, destination tag routing for easy rerouting, one rerouting hop, resulting in a low collision ratio. From our simulation results, the HPCMIN results in a lower collision ratio than other dynamic rerouting networks. The HPCMIN is embedded with the indirect binary n-cube network(the ICube network) which is equivalent to many important MINs. Thus, the design methods used in the HPCMIN can be applied to these MINs so that they have the characteristics of the HPCMIN.
