The technical concern raised during the WG poll has not been resolved so the
history definetely matters.
Quoting RFC5921:
There are thus two objectives for MPLS-TP:
1. To enable MPLS to be deployed in a transport network and operated
in a similar manner to existing transport technologies.
2. To enable MPLS to support packet transport services with a
similar degree of predictability to that found in existing
transport networks.
Based on the extensive comments provided by transport operators and ITU-T
community, the solution in this draft is useless in case 1.
The fact that the solution in this draft is not backward compatible with
existing IP/MPLS BFD implementations means that this solution is also uselesee
in case 2.
Are there other undocumented use cases for MPLS-TP deployments?
