scope:

This Recommendation specifies the protocol used between a policy decision physical entity (PD-PE) and a customer premises network (CPN) gateway policy enforcement physical entity (CGPE-PE). The functional requirements of the Rh interface are contained in [ITU-T Y.2111]. The Rh interface between a PD-PE in the access network and a CGPE-PE can be handled by quality of service (QoS) resource control modes, such as push mode and pull mode. That is, the Rh interface allows the final admission decisions to be installed (either pushed or pulled) to the CGPE-PE from the PD-PE.

The normative part of this Recommendation uses or refers to messages which are defined, and whose behaviours are described, in one or more IETF RFCs. To help the users of this Recommendation, a list of all these messages and their origins are provided in Annex B.
