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
   extending RFC 6374 performance measurements from flows carried over
   MPLS-TP to flows carried over generic 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 generic MPLS networks.
