Abstract
A method and system for transmitting data among a plurality of cards in a crossbar interconnect network having a plurality of cards each having source paths and destination paths utilizes a plurality of source arbitrators and a plurality of destination arbitrators each associated with the cards. The source arbitrators generate connection request commands from the source paths requesting access to a desired destination path and broadcasts the request for receipt by all of the destination arbitrators. The destination arbitrator 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 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 stores the connection request command in one of a plurality of buffers until the desired destination path becomes available.
