MPLS-TP Intro
GANT global connectivity and projects
MPLS-TP is the result of a
joint effort between the ITU-T
and the IETF.
MPLS-TP is a subset of MPLS
with extensions to support the
requirements for transport
networks.

Services (Point-to-point, multipoint-to-multipoint).
MPLS-TP OAM.
BFD demo.
LSP ping.
ITU-T Y.1731 demo (CV, LM and DM).1+1 protection with BFD.
1+1 protection with CV and dDEG.
Management system.
Control plane.
Topology discovery.
Tunnel and PW creation.
MPLS-TP testing during Y4:
In-house testing with ALU 1850 TSS platform.

MPLS-TP Conclusions and questions
Main conclusions:
Implementations not fully mature.
Different approaches.
OAM tools not compatible.
Control plane not fully deployed.
MPLS-TP and IP/MPLS seamless interoperability not ready.
MPLS-TP in MSPP platforms can be an advantage for organizations withlegacy networks.
IP/MPLS networks can make good use of new OAM tools, new protection
and restoration capabilities, and maybe NMS to simplify operations.
Use of end-to-end multi-segment MPLS-TP tunnels to transport services
requires vendor interoperability.
Open questions for tomorrow:
MPLS-TP vs IP/MPLS or PBB-TE.
MPLS-TP instead of OTN?
Ethernet OAM or MPLS-TP OAM?
Control plane or NMS?
