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

1. Introduction
Development and deployment of the Two-Way Active Measurement Protocol
(TWAMP) [RFC5357] and its extensions (e.g., [RFC6038], which defines
Symmetrical Size for TWAMP) provided invaluable experience. Several
independent implementations of both TWAMP and TWAMP Light exist, have
been deployed, and provide important operational performance
measurements.
At the same time, there has been noticeable interest in using a more
straightforward mechanism for active performance monitoring that can
provide deterministic behavior and inherent separation of control
(vendor-specific configuration or orchestration) and test functions.
Recent work on "Performance Measurement from IP Edge to Customer
Equipment using TWAMP Light" [BBF.TR-390] by the Broadband Forum
demonstrates that interoperability among implementations of TWAMP
Light is difficult because the composition and operation of TWAMP
Light were not sufficiently specified in [RFC5357]. According to
[RFC8545], TWAMP Light includes a subset of TWAMP-Test functions.
Thus, to have a comprehensive tool to measure packet loss and delay
requires support by other applications that provide, for example,
control and security.
This document defines an active performance measurement test
protocol, Simple Two-way Active Measurement Protocol (STAMP), that
enables measurement of both one-way and round-trip performance
metrics, like delay, delay variation, and packet loss. Support of
some optional TWAMP extensions, e.g., [RFC7750], is discussed in
[STAMP-OPTION].
