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

摘要

This disclosure provides for admission control having enhanced quality of service. A server-resident admission control system implements measurement-based admission control to determine whether a requested web site is available to process a new session. If the site is not available, based upon current resources and defined load parameters, the server- based system determines when the associated server can later provide preferred access to the client, and transmits to the client an indication of that time, together with a key. One example uses a downloaded web page to automatically cause a client browser to later automatically access the host, and to display a message indicating that the client has preferred access together with a countdown time. As an alternative, a program file can be stored on the client which is effective to launch the client's web browser and to direct access to the particular host at the appointed time, irrespective of whether the client's browser is active.
