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]. 2. Conventions Used in This Document 2.1.
