Resource control protocol No. 3 – Protocols at the Rw interface between a policy decision physical entity (PD-PE) and a policy enforcement physical entity (PE-PE): Diameter profile version 3 (Study Group 11)
This Recommendation provides the stage 3 specification of the protocol at the interface between a policy decision physical entity (PD-PE) and a policy enforcement physical entity (PE-PE). The functional requirements and the stage 2 specifications for this interface are contained in clause 9.2 of [ITU-T Y.2111] and in [b-ITU-T Q-Sup.51]. This interface is used to control policy enforcement functions in the transport devices@ including QoS resource control (e.g.@ packet marking@ filtering and policing)@ gate control@ and network address and port translation etwork address translation (NAPT/NAT) traversal control. The PE-PE may reside in any injection node across access networks@ core networks and the network border gateway. This Recommendation defines: ?C The information to be exchanged between the PD-PE and the PE-PE over the Rw interface. ?C An Rw interface definition based on the Diameter protocol.
