The system includes a FIFO (first-in-first-out) input queue for each node and means for arbitrating the top of each queue for providing the arbitrated output to a given node and means when the top of the input queue has no request for a given node arbitrating the requests from the next to the top entry of the input queues and providing the data from the next to top entry associated with the arbitrated request to the given node.
