scope:
This Recommendation provides the stage 3 specification of the protocol at the interface between policy decision physical entities (PD-PE) and policy enforcement physical entity (PE-PE). The functional requirements and the stage 2 specifications for this interface are contained in clause 8.2 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 NAPT/NAT traversal control. The PE-PE may reside in any injection node across access networks, core networks and network border gateway.
This Recommendation defines:
- The information to be exchanged between the PD-PE and the PE-PE over the Rw interface.
- An Rw interface definition based on the Diameter protocol.
