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.
