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
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) (including the
necessary management objects expressed as MIB modules
or using other techniques).
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 e.g., CCAMP, PWE3,
and OPSAWG working groups.
- Evolve key MPLS protocols, including LDP, tLDP, mLDP, RSVP-TE
and LSP Ping to meet new requirements.
- Define an overall OAM framework for topology-driven, traffic
engineered, and transport profile MPLS applications.
- Determine MPLS-specific aspects of traffic engineering for
multi-areas/multi-AS in cooperation with the CCAMP WG
- Define necessary extensions for MPLS key protocols for
dual-stack and IPv6 only networks
- Coordinate with the CCAMP working group on the extensions of
MPLS and GMPLS protocols
- Document current implementation practices for MPLS load sharing.
- Document mechanisms for securing MPLS networks in coordination
with the KARP working group.
- Document mechanisms for adding multi-topology support to
existing MPLS protocols.
- Document use cases for MPLS protocols.
