Abstract:
1. A method for dynamically adjusting a Resource Reservation Setup Protocol (RSVP) reservation within a hardware communication system, comprising: facilitating an exchange of media streams between a first endpoint and a second endpoint during a call, the media streams comprising a video stream, wherein the first endpoint and the second endpoint use RSVP reservations to reserve bandwidth for exchanging the media streams, wherein each media stream is supported by a RSVP reservation; determining an initial estimated bandwidth for each RSVP reservation to begin exchanging the media streams without knowing how much bandwidth is needed for each RSVP reservation; monitoring each media stream during the call between the first endpoint and the second endpoint; determining whether a capability change occurs during the call, the capability change resulting from transfer of the call to a third endpoint without video capability; and adjusting the bandwidth of the RSVP reservation associated with the video media stream by releasing the RSVP reservation of the video stream if the capability change occurs during the call.
