1.  Introduction

   [I-D.fioccola-spring-flow-label-alt-mark] describes how the alternate
   marking method can be used as the passive performance measurement
   method in an IPv6 domain, actually the alternate marking method can
   also be applied to an MPLS domain, and what's missed is the
   encapsulation for MPLS performance measurement with alternate marking
   method.

   [RFC8372] discusses the desired capabilities for MPLS flow
   identification, in order to perform a better in-band performance
   monitoring of user data packets.  Synonymous Flow Label (SFL), which
   is introduced in [I-D.ietf-mpls-sfl-framework], is identified as a
   method of accomplishing MPLS flow identification.  This document
   employs a method, other than SFL, to accomplish MPLS flow
   identification.  The method described in this document is simple and
   flexible, furthermore, it complies with the current MPLS forwarding
   paradigm.

   This document defines the encapsulation for MPLS performance
   measurement with alternate marking method, which performs flow-based
   packet loss, delay, and jitter measurements on live traffic.
