Abstract: A method and system (10) for transmitting data among a plurality of cards (12a, 12b) in a crossbar interconnect network (30) having a plurality of cards (12a, 12b) each having source paths (16) and destination paths (14) utilizes a plurality of sources arbitrators (22) each associated with the cards. The source arbitrators generate connection request commands from the source paths requesting access to a desired destination of the destination paths and broadcasts the request for receipt by all of the destination arbitrators (24). The destination arbitrators (24) associated with the desired destination path captures the connection request command and processes the command based on whether or not the desired destination path is busy. If the desired destination path is not busy, the destination arbitrator (24) generates a connection command requesting a connection be made between the source path and the desired destination path. If the desired destination path is busy, the destination arbitrator (24) stores the connection request command in one of the plurality of buffers (20) until the desired destination path is available.
