Abstract
Abstract An interconnection topography for microprocessor-based communication nodes consists of opposite arrays of client nodes and resource nodes, with each client node connected to one resource node by a data transfer link, each resource node connected to a resource trunk by a data transfer link, and each node connected to just four neighboring nodes by data transfer links. Communication nodes in the topography are microprocessor controlled, and comprise random access memory and data routing circuitry interfaced to the data transfer links. In one aspect resource nodes are provided with a map of the interconnection topography for use in routing data. In another aspect, individual ones of the communication nodes are programmed as servers for receiving client requests and scheduling routing of resource data.
