Technical Summary
Many MPLS implementations have supported multipath techniques and
many MPLS deployments have used multipath techniques, particularly in
very high bandwidth applications, such as provider IP/MPLS core
networks. MPLS-TP has strongly discouraged the use of multipath
techniques. Some degradation of MPLS-TP OAM performance cannot be
avoided when operating over many types of multipath implementations.
Using MPLS Entropy label, MPLS Label Switched Paths (LSPs) can be
carried over multipath links while also providing a fully MPLS-TP
compliant server layer for MPLS-TP LSPs. This document describes the
means of supporting MPLS as a server layer for MPLS-TP. The use of
MPLS-TP LSPs as a server layer for MPLS LSPs is also discussed.
Working Group Summary
Nothing in particular to note, no controversies and the working is solidly
behind this document.
Document Quality
This is an Informational document that has been well reviewed in the
working, but not external reviews have been necessary.
As part of the working group reviews it has also been reviewed by
the MPLS review team (MPLS-RT) prior to adoption as a working
group document.
No specific implementation review has been done on this
document since we don't expect any direct vendor implementations
of the document; instead the document discusses how the mechanisms
that have been implemented can be use. We know of operators
that has deployed the techniques discussed in the document.
The MPLS-RT reviewers has been Mach Chen, Markus Jork, David Allan
and Carlos Pignataro.
