ABSTRACT:
A modular growable packet switching arrangement is constructed from a plurality of packet switches and a novel interconnect fabric. The interconnect fabric includes a plurality of cell routers, for receiving data packets and routing them to a plurality of packet switches, where each cell router includes at least one connection to each packet switch. The interconnect fabric also includes a sorting network for receiving concurrently arriving data packets, sorting the data packets based upon their addresses, and sending the sorted data packets to the inputs of the cell routers. The sorted data packets are arranged such that all data packets which must be transmitted to the same packet switch are sent to different cell routers. Then, all packets which are destined for a common packet switch may be routed there, each from a different cell router.
