A scalable and high capacity router on multi-dimension crossbar switch principle

Eventhough conventional multistage switch architecture such as a Banyan switch can support a high speed capacity, but it still has a high latency and is not scalable. Moreover under non-uniform traffic, blocking occurs. Therefore, a new switch architecture based on multi-dimensional crossbar (MDXB) switch is introduced, as a better solution. The MDXB switch is an interconnection among crossbar switches into multi-dimension network. We also propose a new node configuration and routing algorithm used in the MDXB switch to achieve even lower packet loss rate. The simulation results shown that MDXB switch achieves much higher throughput under a non-uniform traffic pattern
