The IESG has received a request from the Path Computation Element WG (pce) to consider the following document: - 'Path Computation Element Communication Protocol (PCEP) Extensions for Associated Bidirectional Segment Routing (SR) LSPs' <draft-ietf-pce-sr-bidir-path-21.txt> as Proposed Standard
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2026-02-20. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Path Computation Element Communication Protocol (PCEP) provides mechanisms for Path Computation Elements (PCEs) to perform path computations in response to Path Computation Clients (PCCs) requests. Segment Routing (SR) can be used to steer packets through a network employing the source routing paradigm. SR can be applied to both MPLS (SR-MPLS) and IPv6 (SRv6) data planes. Stateful PCEP extensions for SR allow a PCE to maintain state and to control and initiate SR Traffic Engineering (TE) LSPs. PCEP supports grouping of two unidirectional MPLS-TE Label Switched Paths (LSPs), signaled via RSVP-TE, using association. This document defines PCEP extensions for grouping two unidirectional SR LSPs (one in each direction in the network) into a single associated bidirectional SR LSP. The mechanisms defined in this document are applicable to both stateless and stateful PCEs for PCE-initiated and PCC-initiated LSPs.
