RFC6374 Synonymous Flow Labels
draft-ietf-mpls-rfc6374-sfl-09
Abstract
RFC 6374 describes methods of making loss and delay measurements on
Label Switched Paths (LSPs) primarily as used in MPLS Transport
Profile (MPLS-TP) networks. This document describes a method of
making RFC 6374 performance measurements on flows carried over
general MPLS LSPs. In particular, it extends the technique to allow
loss and delay measurements to be made on multi-point to point LSPs
and introduces some additional techniques to allow more sophisticated
measurements to be made in both MPLS-TP and general MPLS networks.
