Subject: WG Review: Multiprotocol Label Switching (mpls)
The Multiprotocol Label Switching (mpls) WG in the Routing Area of the IETF
is undergoing rechartering. The IESG has not made any determination yet. The
following draft charter was submitted, and is provided for informational
purposes only. Please send your comments to the IESG mailing list
(iesg@ietf.org) by 2025-07-19.

Charter: https://datatracker.ietf.org/doc/charter-ietf-mpls/
The MPLS working group is responsible for standardizing technology for label
switching and for the implementation of label-switched paths over packet
based link-level technologies.
The working group's responsibilities include: procedures and protocols for
the distribution of labels between Label Switching Routers (LSRs); MPLS
encapsulation and emulation of Layer 1, Layer 2, and Layer 3 frames, packets,
and services that run over MPLS; and mechanisms for Operation,
Administration, and Maintenance (OAM) for MPLS systems including the
necessary management objects expressed as YANG data models.
The current WG focus areas and work items are:
• Maintain existing MPLS requirements, mechanisms, and protocols, as
currently documented in RFCs, in coordination with other working groups that
work in overlapping areas including the BESS, BFD, BIER, CCAMP, DETNET, IDR,
IPPM, OPSAWG, SPRING, and TEAS working groups. • Maintain and evolve
key MPLS protocols to meet new requirements: LDP (including Targeted LDP
(tLDP) and Multipoint LDP (mLDP)), RSVP-TE for packet networks, and LSP Ping.
• Maintain existing MPLS-based static and LDP-signaled pseudowire and
L2VPN requirements, mechanisms, and protocols as currently documented in
RFCs, and enhance them. Ensure that MPLS can continue to support these
applications, as well as other MPLS based signaled PWs as they evolve. •
Document use cases for MPLS protocols. • Document MPLS-specific
aspects of traffic engineering including multi-areas/multi-AS scenarios in
cooperation with the TEAS working group. • Coordinate the work on
RSVP-TE with CCAMP and TEAS. In the cases where there is an overlap, generic
parts will be done by the TEAS working group, MPLS data plane specific parts
will be done by the MPLS working group, and support for any other specific
data planes will be done by the CCAMP working group. The TEAS working group
acts as the hub for coordinating this work, and the MPLS working group will
track agreements about work to be done in this working group through
milestones in this charter. • Define YANG data models for MPLS working
group related solutions. Coordinate with other working groups (such as
NETMOD) for core YANG data models. • Define an overall OAM framework
for applications that are topology-driven, traffic engineered or utilize
transport profile MPLS to achieve a common set of approaches and mechanisms
across the full family of applications that use MPLS. • Document
mechanisms for securing MPLS protocols and data plane. • Define a
framework and encapsulations for MPLS Network Actions (MNA). Document use
cases for MNA and define solutions for those use cases.
Note: All documents will be standards track unless otherwise specified in the
milestones.
