Abstract

A stateful Path Computation Element (PCE) retains information about the placement of Multiprotocol Label Switching (MPLS) Traffic Engineering Label Switched Paths (TE LSPs). When a PCE has stateful control over LSPs, it may send indications to LSP head-ends to modify the attributes (especially the paths) of the LSPs. A Path Computation Client (PCC) that has set up LSPs under local configuration may delegate control of those LSPs to a stateful PCE.

There are use cases in which a stateful PCE may wish to obtain control of locally configured LSPs that it is aware of but have not been delegated to the PCE.

This document describes an extension to the Path Computation Element Communication Protocol (PCEP) to enable a PCE to make requests for such control.
