Abstract
These exemplary embodiments utilize Sessions Initiation Protocol (SIP) for admission control. The use of the SIP allows a SIP server itself to perform the admission control function. The use of RSVP linkages is reduced. The use of SIP for admission control allows an application to communicate, or “talk,” to a network and to request that resources within the network be reserved. Any communications device that uses sessions may utilize the SIP protocol for admission control. The SIP protocol may be used for unicast and multicast media sessions including video-on-demand and/or multicast video access control.
