A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Path Computation Element WG of the IETF. Title : Ability for a Stateful Path Computation Element (PCE) to request and obtain control of a Label Switched Path (LSP) Authors : Aswatnarayan Raghuram Al Goddard Jay Karthik Siva Sivabalan Mahendra Singh Negi Filename : draft-ietf-pce-lsp-control-request-10.txt Pages : 12 Date : 2019-10-13 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 of which it is aware but that 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.
