Path Computation Element Communication Protocol Extensions for Associated Bidirectional Label Switched Paths
RFC 9059, “Path Computation Element Communication Protocol Extensions for Associated Bidirectional Label Switched Paths”, is a Proposed Standard document published in June 2021 by R. Gandhi, C. Barth, B. Wen. It has since been updated by RFC 9756. The canonical text is published by the RFC Editor.
Abstract
This document defines Path Computation Element Communication Protocol (PCEP) extensions for grouping two unidirectional MPLS-TE Label Switched Paths (LSPs), one in each direction in the network, into an associated bidirectional LSP. These PCEP extensions can be applied either using a stateful PCE for both PCE-initiated and PCC-initiated LSPs or using a stateless PCE. The PCEP procedures defined are applicable to the LSPs using RSVP-TE for signaling.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
