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
   collection at every node that STAMP test packets traverse.

1.  Introduction

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

   This document extents optional TLVs to STAMP which enable OAM data
   collection at every node that STAMP test packets traverse, such as
   measurement of delay, packet loss, delay variation per hop, and
   record of route information.  STAMP Extensions have defined several
   optionnal TLVs to enhance the STAMP base functions.  These optional
   TLVs are defined as updates of the STAMP Optional Extensions
   [I-D.ietf-ippm-stamp-option-tlv].  The following sections describe
   the use of TLVs for STAMP that extend STAMP capability beyond its
   base specification.
