The IESG has approved the following document: - 'Use of Multipath with MPLS and MPLS-TP' (draft-ietf-mpls-multipath-use-04.txt) as Informational RFC This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Stewart Bryant. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-multipath-use/ 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.
