Title : Supporting Shared Mesh Protection in MPLS-TP Networks

Shared mesh protection is a common protection and recovery mechanism
in transport networks, where multiple paths can share the same set
of network resources for protection purposes.
In the context of MPLS-TP, it has been explicitly requested as a
part of the overall solution (Req. 67, 68 and 69 in RFC5654 [1]).
It's important to note that each MPLS-TP LSP may be associated with
transport network resources. In event of network failure, it may
require explicit activation on the protecting paths before switching
user traffic over.
In this memo, we define a lightweight signaling mechanism for
protecting path activation in shared mesh protection-enabled MPLS-TP
networks.
