Abstract

   This document describes a method of making RFC6374 performance
   measurements on flows carried over an MPLS Label Switched path.  This
   allows loss and delay measurements to be made on multi-point to point
   LSPs and allows the measurement of flows within an MPLS construct
   using RFC6374.
