                        draft-ietf-ippm-stamp-03

Abstract

   This document describes a Simple Two-way Active Measurement Protocol
   which enables measurement of both one-way and round-trip performance
   metrics like delay, delay variation, and packet loss.

1.  Introduction

   Development and deployment of Two-Way Active Measurement Protocol
   (TWAMP) [RFC5357] and its extensions, e.g., [RFC6038] that defined
   features such as Reflect Octets and Symmetrical Size for TWAMP
   provided invaluable experience.  Several independent implementations
   exist, have been deployed and provide important operational
   performance measurements.  At the same time, there has been
   noticeable interest in using a simpler mechanism for active
   performance monitoring that can provide deterministic behavior and
   inherit separation of control (vendor-specific configuration or
   orchestration) and test functions.  One of such is Performance
   Measurement from IP Edge to Customer Equipment using TWAMP Light from
