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.

MPLS-TP testing in JRA1 T1

Main testing:

MPLS-TP architecture.

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?
