ABSTRACT:
A data network including at least one crossbar, wherein each crossbar comprises N ports and a plurality N of devices each associated with and connected to one port of one of the crossbars. Each one port of one crossbar includes an input buffer, a plurality N−1 of port output buffers, a plurality N−1 of fullness sensors, shutoff devices. The input buffer receives messages from the device connected to its port and sends the messages to the other ports of the one crossbar. Each port output buffers corresponds to one of the other ports, wherein each port output buffer receives the messages only from the input buffer of its associated other port. Each fullness sensor is associated with one port output buffer and measures the fullness state of its associated port output buffer.
