Recommendation ITU-T H.248.65 provides an ITU-T H.248 package for the support of the resource reservation protocol (RSVP). The protocol capabilities are tightly coupled with the pull mode defined in Recommendation ITU-T H.248.55. The RSVP extension package complements the generic pull mode package by providing additional capabilities for the specific path-coupled QoS/resource control protocol RSVP. This package allows the ITU-T H.248 entities to make the resource reservation, i.e., set up the bearer path with the desired QoS. Based on this package, the MGC and the MG are able to initiate/terminate the RSVP messages.
