Resource control protocol No. 3 ?Protocol at the interface between a Policy Decision Physical Entity (PD-PE) and a Policy Enforcement Physical Entity (PE-PE): COPS alternative Study Group 11
This Recommendation provides the Stage 3 technical specifications for the COPS profile at the
interface between the policy decision physical entity (PD-PE) and the 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]. This protocol profile allows the final admission
decisions to be installed (either push or pull mode) to PE-PE from PD-PE, supports the resource
control for both fixed and mobile networks and supports the NAPT control and NAT traversal at
PE-PE as needed.
This Recommendation provides resource control procedure, protocol profile, message and the
definition and application of the policy information base.
