Paper Abstract

While fiber optic packet switched networks can make use of the advantages provided by optics for transmission of messages, it is not possible to provide an efficient storage mechanism at intermediate nodes for data that remains in optical format. Hence, it is necessary to avoid conversion to electronic format for temporary storage at intermediate nodes when they face output port contention. As a result, in order to maintain fast packet switching, optical packets must be continuously moved until they reach their destination. In such bufferless networks, if two or more packets coming into a node simultaneously request the same output port, one of the requests can be satisfied and the others must be sent out through other available ports. The addition of time switching, to the usual space switching using this deflection routing technique, allows temporal reordering of packets so as to reduce the contention for spatial channels. In this paper we present the performance enhancement due to space-time switching in bufferless packet switched networks.
