Abstract
A crossbar bus network of nodes is coupled to a crossbar switch circuit that operates as a communications hub routing messages simultaneously to and from the nodes over multiple links. The crossbar switch circuit includes a dedicated communications bus ring adapted to transmit data such as programmed input/output (PIO) messages between components of said crossbar switch circuit. The communications bus ring can be used for secondary high latency data communications thereby freeing switching matrix links of the crossbar switch circuit for simultaneous unimpeaded important low latency data communications to the same device.
