STAMP

This document defines an optional extension to the Simple Two-way Active Measurement Protocol (STAMP) that enables a Session-Reflector to send asymmetrical packets, that is, response packets whose size or quantity differs from those sent by the Session-Sender. While standard STAMP exchanges are symmetrical, certain measurement scenarios benefit from reflected packets of different lengths or additional responses to better approximate application traffic conditions. The extension specifies the Reflected Test Packet Control TLV and associated procedures, analyzes challenges in active performance measurement (including in multicast environments), and describes STAMP behaviors to improve measurement efficiency and reduce network impact.

This document extends Simple Two-way Active Measurement Protocol (STAMP) to implement performance measurement on every member link of a Link Aggregation Group (LAG). Knowing the measured metrics of each member link of a LAG enables operators to enforce a performance-based traffic steering policy across the member links.

Segment Routing (SR) leverages the source routing paradigm. SR is applicable to both Multiprotocol Label Switching (SR-MPLS) and IPv6 (SRv6) forwarding planes. This document specifies Simple Two-Way Active Measurement Protocol (STAMP) extensions (as described in RFC 8762) for SR networks, for both the SR-MPLS and SRv6 forwarding planes, by augmenting the optional extensions defined in RFC 8972.

This document describes optional extensions to Simple Two-way Active Measurement Protocol (STAMP) that enable measurement of performance metrics. The document also defines a STAMP Test Session Identifier and thus updates RFC 8762.

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.
