A novel switch architecture for high-performance computing and signal processing networks

This work describes low-latency switch architecture for high performance packet-switched networks. The switch architecture is a combination of input buffers capable of avoiding head-of-line blocking and an internal switch interconnect capable of allowing different input ports to access a single output port simultaneously. The switch was designed for the RapidIO protocol, but provides improved performance in other switched fabrics as well. OPNET Modeler was used to develop models of the proposed switch architecture and to evaluate the performance of the switch for three different network topologies. Models of two standard switch architectures were also developed and simulated for comparison.
