Network communication unit using an adaptive router

Abstract From the Canadian patent

A parallel processor network comprised of a plurality of nodes each node , including a processor containing a number of I/O ports and a local memory. A , communication path is established through a node by comparing a target node address in a first address packet with a processor ID of the node. If node address is equal to the target node address a receive channel is allocated to the input port and a route ready command is sent over an output port paired with the input port. If the node address is not equal to the target node address, then a first unallocated output port is selected from a port vector and the address packet is forwarded to a next node over the selected output port.
