OSPF Protocol Extensions for Path Computation Element Discovery
RFC 5088, “OSPF Protocol Extensions for Path Computation Element Discovery”, is a Proposed Standard document published in January 2008 by JL. Le Roux, JP. Vasseur, Y. Ikejiri, R. Zhang. It has since been updated by RFC 9353. The canonical text is published by the RFC Editor.
Abstract
There are various circumstances where it is highly desirable for a Path Computation Client (PCC) to be able to dynamically and automatically discover a set of Path Computation Elements (PCEs), along with information that can be used by the PCC for PCE selection. When the PCE is a Label Switching Router (LSR) participating in the Interior Gateway Protocol (IGP), or even a server participating passively in the IGP, a simple and efficient way to announce PCEs consists of using IGP flooding. For that purpose, this document defines extensions to the Open Shortest Path First (OSPF) routing protocol for the advertisement of PCE Discovery information within an OSPF area or within the entire OSPF routing domain.

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.
