1.  Introduction

   The Alternate Marking [RFC8321] technique is an hybrid performance
   measurement method, per [RFC7799] classification of measurement
   methods.  Because this method is based on marking consecutive batches
   of packets.  It can be used to measure packet loss, latency, and
   jitter on live traffic.

   For the basic Alternate Marking method, bits are needed to record the
   mark.  However, in some protocols, no additional bit can be used,
   which blocks the wide deployment of the alternate marking technique.
   And the basic Alternate Marking method is limited with the
   scalability for further extension, i.e, more measurements in addition
   to existing use.

   This document defines data fields for the alternate marking with
   enough space.  More information can be considered within the
