Charter (as of 2015-10-14):
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 packet encapsulation, and for Operation, Administration, and Maintenance (OAM) for MPLS systems including the necessary management objects expressed as YANG models or MIB modules.
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, CCAMP, OPSAWG, PALS, SPRING, and TEAS working groups.
- Evolve key MPLS protocols, including LDP, tLDP, mLDP, RSVP-TE for packet networks, and LSP Ping to meet new requirements.
- Document MPLS-specific aspects of traffic engineering including for 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 data models for MPLS working group related solutions. YANG models and MIB modules may be considered. Coordinate with the LIME and NETMOD working groups for core YANG models.
- Define an overall OAM framework for topology-driven, traffic engineered, and transport profile MPLS applications to achieve a common set of approaches and tools across the full family of MPLS applications.
- Define the necessary extensions for MPLS key protocols for dual- stack and IPv6-only networks.
- Document current implementation practices for MPLS load sharing.
- Document mechanisms for securing MPLS protocols and data plane.
- Document mechanisms for adding multi-topology support to existing MPLS protocols.
- Define the necessary protection protocols and scenarios for transport profile MPLS applications
- Document use cases for MPLS protocols.
