METHODS, APPARATUS AND SYSTEM FOR CREATING SR POLICY USING PATH COMPUTATION ELEMENT PROTOCOL - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18336058 Titled 'METHODS, APPARATUS AND SYSTEM FOR CREATING SR POLICY USING PATH COMPUTATION ELEMENT PROTOCOL'
Simplified Explanation
This abstract describes a method for creating a Segment Routing (SR) policy using extensions to the Path Computation Element Protocol (PCEP). In this method, a PCE communicates with a PCC using PCEP mechanisms. The PCE sends an initiate message to the PCC, containing instructions from the central controller (CC) and an identifier for creating an SR policy. The PCC receives this message and creates the SR policy using the specified parameters. The PCC then sends a report message to the PCE, acknowledging the CC identifier and informing about the newly created SR policy.
Original Abstract Submitted
The present disclosure provides a mechanism to support the creation of an SR policy using PCEP extensions. In one implementation, a PCE is in communication with a PCC using PCEP mechanisms. The PCE sends a first PCEP initiate message, PCInitiate, to the PCC, where the first PCEP message carries the central controller instruction with CC-ID for creating an SR policy. The PCC receives the first PCEP initiate message from the PCE, creates the SR policy using the SR policy parameters where the SR policy is a container independent of any candidate path. Further, the PCC sends a first PCEP report message, PCRpt, to the PCE to report the acknowledgement of the CC-ID and the newly created SR policy.
