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

Eventhough conventional multistage switch architecture such as Banyan switch can support high speed capacity, but it still has 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. MDXB switch is an interconnection among crossbar switches into multi-dimension network. In this paper, we also propose a new node configuration and routing algorithm used in MDXB switch to achieve even lower packet loss rate. The simulation results shown that MDXB switch achieves much higher throughput under non-uniform traffic pattern.
