 Multipoint Alternate Marking method for passive and hybrid performance

Abstract

   The Alternate Marking method, as presented in
   [I-D.ietf-ippm-alt-mark], 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.
