Title: Digital data communications system packet switch

Abstract: A data communications system designed to facilitate communications between digital computers typically routes fixed-length segments of data, called packets, through minicomputer packet switches located intermediate the digital computers. To mitigate the need for expensive minicomputer arrangements as the intermediate processor, the minicomputers are replaced by a low-cost, high-throughput, modular packet switch having an efficient control memory-queue control arrangement for moving a packet from one time slot to another as well as modifying the packet header as the packet is routed through the communications system.
