A Queue Manager (QM) system and method are provided for communicating control messages between processors. The method accepts control messages from a source processor addressed to a destination processor. The control messages are loaded in a first-in first-out (FIFO) queue associated with the destination processor. Then, the method serially supplies loaded control messages to the destination processor from the queue. The messages may be accepted from a plurality of source processors addressed to the same destination processor. The control messages are added to the queue in the order in which they are received. In one aspect, a plurality of parallel FIFO queues may be established that are associated with the same destination processor. Then, the method differentiates the control messages into the parallel FIFO queues and supplies control messages from the parallel FIFO queues in an order responsive to criteria such as queue ranking, weighting, or shaping.
