Abstract:

   This document specifies an optional extension to the Simple Two-way
   Active Measurement Protocol (STAMP) to control the length and/or
   number of packets sent by a Session-Reflector in response to a single
   test packet from the Session-Sender during a STAMP test session.  By
   default, a STAMP Session-Sender and Session-Reflector exchange
   packets symmetrically: the number of packets sent by the Session-
   Reflector and the Session-Sender are the same as is the length of the
   packets sent by the Session-Reflector and the Session-Sender.
   However, there are cases where a Session-Reflector responding with
   Asymmetrical Packets would ensure a closer approximation between
   active performance measurements and the conditions experienced by
   monitored application.  The STAMP extension proposed in this document
   allows the operator to establish tests where a Session-Reflector
   sends Asymmetrical Packets, packets whose length is not symmetrical
   to test packet sent by the Session-Sender and/or packets that are not
   sent in direct response to a packet received from a Session-Sender.
   The document also includes an analysis of challenges related to
   performance monitoring in a multicast network.  It specifies
   procedures and STAMP extensions to achieve more efficient
   measurements with a lesser impact on a network.
