Abstract

   The Alternate Marking method, as presented in RFC 8321 [RFC8321], 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 aims to generalize and expand 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.  Some definitions
   here introduced extend the scope of RFC 5644 [RFC5644] in the context
   of alternate marking schema.
