     Simple Two-way Active Measurement Protocol Optional Extensions
                 draft-mirsky-ippm-stamp-option-tlv-02

Abstract

   This document describes optional extensions to Simple Two-way Active
   Measurement Protocol (STAMP) which enable measurement performance
   metrics in addition to ones enabled by the STAMP base specification.

1.  Introduction

   Simple Two-way Active Measurement Protocol (STAMP)
   [I-D.ietf-ippm-stamp] supports the use of optional extensions that
   use Type-Length-Value (TLV) encoding.  Such extensions are to enhance
   the STAMP base functions, such as measurement of one-way and round-
   trip delay, latency, packet loss, as well as ability to detect packet
   duplication and out-of-order delivery of the test packets.  This
   specification provides definitions of optional STAMP extensions,
   their formats, and theory of operation.
