Title:
METHODS, APPARATUS AND SYSTEM FOR CREATING SR POLICY USING PATH COMPUTATION ELEMENT PROTOCOL
Document Type and Number:
WIPO Patent Application WO/2022/127936
Kind Code:
A1
Abstract:
The present disclosure provides a mechanism to support creation of a SR policy using PCEP extensions. In one implementation, a PCE (130) is in communication with a PCC (112) using PCEP mechanisms. The PCE (130) sends a first PCEP initiate message, PCInitiate, to the PCC (112), where the first PCEP message carries the central controller instruction with CC-ID=X for creating a SR policy. The PCC (112) receives the first PCEP initiate message from the PCE (130), creates the SR policy using the SR policy parameters where the SR policy is a container independent of any candidate path. Further, the PCC (112) sends a first PCEP report message, PCRpt, to the PCE (130) to report the acknowledgement of the CC-ID=X and the newly created SR policy.
