Admission control system with messages admitted or deferred for re-submission at a later time on a priority basis

An improvement in an admission control system that selectively admits and defers incoming messages sent from at least one client system, the admission control system consisting of at least one of software, firmware and hardware to effect admission control for a server, said improvement comprising:

• determining whether incoming messages correspond to a session in-progress and admitting to the server those incoming messages which do correspond to a session in-progress;
• for incoming messages not corresponding to a session in-progress, comparing current server processing resources with at least one predetermined parameter and responsively determining whether a session corresponding to the message can be processed without burdening server processing resources beyond an amount indicated by a predetermined parameter;
• for incoming messages not corresponding to a session in-progress,
• determining whether the message has been previously deferred by said admission control system, and
• if the message has been previously deferred by said admission control system, then admitting the message as a new session;
• deferring incoming messages which do not correspond to a session in-progress, have not been previously deferred by said admission control system and cannot be otherwise processed without burdening server resources beyond the amount indicated by a predetermined parameter, including
• assigning a time indicator to those messages which are deferred for later admission to the server on a priority basis, and transmitting an indication of deferral and the time indicator to the client system, and
• creating a priority indicator associated with deferred messages of prior deferral by said admission control system, the priority indicator adapted for use by said admission control system in determining whether a corresponding message has been previously deferred.

An improvement in a browser adapted for use upon a client system to access a host, the browser adapted for use in connection with an admission control system that admits and defers messages on a priority basis, wherein the admission control system includes an admission control gateway and a deferral manager, and the deferral manager both sends to the client system a deferral message indicating that a previously submitted message has been deferred and includes with the deferral message an indication of a time when the deferred message can be later processed by the host, said improvement comprising:

• a buffer adapted to store at least one host address and the indication of time;
• a clock that determines a time when the deferred message can be processed by the host;
• and
• means coupled to the clock for sending at the time determined by the clock a deferred message to the admission control system that enables admission of the deferred message on a priority basis.
