Abstract

   This document defines optional TLVs which are carried in Simple Two-
   way Active Measurement Protocol (STAMP) test packets to enhance the
   STAMP base functions.  Such extensions to STAMP enable OAM data
   measurement and collection at every node and link along a STAMP test
   packet's delivery path without maintaining a state for each
   configured STAMP-Test session at every devices.

1.  Introduction

   Simple Two-way Active Measurement Protocol (STAMP) [RFC8762] enables
   the measurement of both one-way and round-trip performance metrics,
   such as delay, delay variation, and packet loss.  In the STAMP
   session, the bidirectional packet flow is transmitted between STAMP
   Session-Sender and STAMP Session-Reflector.  The STAMP Session-
   Reflector receives test packets transmitted from Session-Sender and
   acts according to the configuration.  However, the performance of
   intermediate nodes and links that STAMP test packets traverse are
   invisible.  In addition, the STAMP instance must be configured at
   every intermediate node to measure the performance per node and link
   that test packets traverse, which increases the complexity of OAM in
   large-scale networks.
