Abstract: In one embodiment, a reservation proxy monitors for received connectivity check messages or beginning-of-media-flow indication messages. When either type of message is observed, the reservation proxy requests resource allocation for a media flow associated with the received message. The amount of resource allocation requested may be coordinated by exchanging messages with a call controller or policy server for one of the endpoints of the media flow, or the amount of resource allocation may be identified within the received message.
