 Multipoint Alternate Marking method for passive and hybrid performance

Abstract

   The Alternate Marking method, as presented in RFC 8321, can be
   applied only to point-to-point flows because it assumes that all the
   packets of the flow measured on one node are measured again by a
   single second node.  This document generalizes and expands this
   methodology to measure any kind of unicast flows, whose packets can
   follow several different paths in the network, in wider terms a
   multipoint-to-multipoint network.  For this reason the technique here
   described is called Multipoint Alternate Marking.

1.  Introduction

   The Alternate Marking method, as described in RFC 8321 [RFC8321], is
   applicable to a point-to-point path.  The extension proposed in this
   document applies to the most general case of multipoint-to-multipoint
   path and enables flexible and adaptive performance measurements in a
