Label Switched Path Object Flag Extension for Stateful PCE

Overview

RFC 9357, “Label Switched Path Object Flag Extension for Stateful PCE”, is a Proposed Standard document published in February 2023 by Q. Xiong. It has since been updated by RFC 9756. The canonical text is published by the RFC Editor.

Abstract

RFC 8231 describes a set of extensions to the Path Computation Element Communication Protocol (PCEP) to enable stateful control of MPLS-TE and GMPLS Label Switched Paths (LSPs) via PCEP. One of the extensions is the LSP object, which includes a Flag field with a length of 12 bits. However, all bits of the Flag field have already been assigned.

This document defines a new LSP-EXTENDED-FLAG TLV for the LSP object for an extended Flag field.
