The IESG has approved the following document: - 'Path Computation Element Communication Protocol (PCEP) Extensions for Associated Bidirectional Segment Routing (SR) LSPs' (draft-ietf-pce-sr-bidir-path-25.txt) as Proposed Standard
This document is the product of the Path Computation Element Working Group. The IESG contact persons are Gunter Van de Velde, Jim Guichard and Ketan Talaulikar. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-pce-sr-bidir-path/ Technical Summary 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. Working Group Summary There was broad consensus in the working group on this work. This work builds on prior specifications published by the WG and extends them for segment routing. There was no controvery or contention with respect to this work. Document Quality There are at least two known/declared shipping commercial implementations of this specification. This specification extends previously published specification for use with segment routing and as such has gone through good reviews with the WG. It has gone through RTGDIR and OPSDIR early reviews and no other review was sought as it does not include any YANG, media type, or such contents. Personnel The Document Shepherd for this document is Dhruv Dhody. The Responsible Area Director is Ketan Talaulikar. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
