Delivery of client remote procedure calls to a server via a request queue utilizing priority and time-out

摘要

A computer system includes at least a server procedure and a client processor. The client processor includes plural applications which issue requests for execution of server procedures. A queue is present in the client processor and lists the requests. The client processor also includes plural input/output procedures which enable dispatch of requests to the server procedure. The client processor operates in conjunction with the I/O procedures, removes a request from the queue, and dispatches the request to the server procedure. The processor responds to occurrence of a time-out, with no response being received from the server procedure, to place the current request at the beginning of the queue so as to enable the I/O procedure to service a further request from the queue. The I/O procedure of the client processor handles requests from the queue, based upon assigned priority levels, and removes from the queue a highest assigned priority request that is closest to the end of the queue, before removing a lower priority request.
