Path Computation Element Communication Protocol (PCEP) Extensions for PCE-Initiated LSP Setup in a Stateful PCE Model
draft-ietf-pce-pce-initiated-lsp-11
Technical Summary
The Path Computation Element Communication Protocol (PCEP) provides
mechanisms for Path Computation Elements (PCEs) to perform path
computations in response to Path Computation Clients (PCCs) requests.
The extensions for stateful PCE provide stateful control of
Multiprotocol Label Switching (MPLS) Traffic Engineering Label
Switched Paths (TE LSP) via PCEP, for a model where the PCC delegates
control over one or more locally configured LSPs to the PCE. This
document describes the creation and deletion of PCE-initiated LSPs
under the stateful PCE model.
Working Group Summary
Given the consensus to consider it, the WG had to update its charter to include
that work, which was at the boundary of the former scope. This I-D
complements draft-ietf-pce-stateful-pce.
Document Quality
There are several implementations, including one open source (OpenDaylight).
Have a significant number of vendors indicated their plan to
implement the specification?
Yes, even more than plans.
Are there any reviewers that merit special mention as
having done a thorough review, e.g., one that resulted
in important changes or a conclusion that the document had no
substantive issues?
Some updates have been triggered by a couple of operators,
thanks to some interoperability testing between several implementations.
