Abstract: In a self-configuring store-and-forward computer network, a plurality of processors are each housed in an enclosure having a top surface and a bottom surface. Each processor has an associated block identification number. An array of m by n radially symmetric connectors are arranged on the top surface and on the bottom surface of each enclosure. Each connector has an associated connector identification number. The connectors physically and electronically couple the plurality of processors as a three-dimensional structure. Communications controller in each of the processors exchange the block and connector identification numbers between the processors and a host computer to determine an ordered list of connector numbers that is used to route messages between any of the processors and the host computer.
