Conveying Path Setup Type in PCE Communication Protocol Messages
RFC 8408, “Conveying Path Setup Type in PCE Communication Protocol Messages”, is a Proposed Standard document published in July 2018 by S. Sivabalan, J. Tantsura, I. Minei, R. Varga, J. Hardwick. It has since been updated by RFC 8664. The canonical text is published by the RFC Editor.
Abstract
A Path Computation Element (PCE) can compute Traffic Engineering (TE) paths through a network; these paths are subject to various constraints. Currently, TE paths are Label Switched Paths (LSPs) that are set up using the RSVP-TE signaling protocol. However, other TE path setup methods are possible within the PCE architecture. This document proposes an extension to the PCE Communication Protocol (PCEP) to allow support for different path setup methods over a given PCEP session.
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.
