Abstract

A plurality of multiprocessor systems is arranged in a high speed network to allow any processor in one system to communicate with any processor in another system. The network is configured as a multi-node dual bidirectional ring having a multiprocessor system at each node. Packets of information may be passed around the ring in either of two directions and are temporarily stored in buffer memory locations dedicated to a selected destination processor in a selected direction between each successive transfer between neighboring nodes. The buffer locations are managed so that they can request an adjacent node to stop transmitting packets if the buffer is becoming full from that direction and request resumption of transmission of packets as the buffer empties.
