Abstract
A distributed digital data processing system includes a host system and a plurality of nodes interconnected by a common bus. The host maintains a common queue buffer which is used to contain queues each associated with a node for transferring messages transferred among all of the nodes in the system. The queue buffer is identified by a common system descriptor block. To perform a transfer, the nodes access the system descriptor block to determine the location of the queue buffer from the common system descriptor block and inserts a message in a queue entries and links it to the queue associated with the intended recipient.
