This Recommendation provides the stage 3 specification of the Rt interface (rcp5). The Rt protocol is used between the policy decision physical entity (PD-PE) and the transport resource control physical entity (TRC-PE) in the resource and admission control functional block. The Rt interface provides the ability for the PD-PE to request the TRC-PE entities in the involved networks to detect and determine the requested QoS resource for a given media flow. The PD-PE may also request the TRC-PE to provide the path selection information for a given flow in the core network. The functional requirements corresponding to this interface are contained in clause 8.5 of [ITU-T Y.2111] and in [ITU-T Q-Sup.51].
