Updated Rules for Processing Stateful PCE Request Parameters Flags
RFC 8786, “Updated Rules for Processing Stateful PCE Request Parameters Flags”, is a Proposed Standard document published in May 2020 by A. Farrel. It updates RFC 8231. The canonical text is published by the RFC Editor.
Abstract
Extensions to the Path Computation Element Communication Protocol (PCEP) to support stateful Path Computation Elements (PCEs) are defined in RFC 8231. One of the extensions is the Stateful PCE Request Parameters (SRP) object. That object includes a Flags field that is a set of 32 bit flags, and RFC 8281 defines an IANA registry for tracking assigned flags. However, RFC 8231 does not explain how an implementation should set unassigned flags in transmitted messages, nor how an implementation should process unassigned, unknown, or unsupported flags in received messages.
This document updates RFC 8231 by defining the correct behaviors.
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.
