Extension of RFC 6374-Based Performance Measurement Using Synonymous Flow Labels

Overview

RFC 9571, “Extension of RFC 6374-Based Performance Measurement Using Synonymous Flow Labels”, is a Proposed Standard document published in May 2024 by S. Bryant, G. Swallow, M. Chen, G. Fioccola, G. Mirsky. The canonical text is published by the RFC Editor.

Abstract

RFC 6374 describes methods of making loss and delay measurements on Label Switched Paths (LSPs) primarily as they are used in MPLS Transport Profile (MPLS-TP) networks. This document describes a method of extending the performance measurements (specified in RFC 6374) from flows carried over MPLS-TP to flows carried over generic MPLS LSPs. In particular, it extends the technique to allow loss and delay measurements to be made on multipoint-to-point LSPs and introduces some additional techniques to allow more sophisticated measurements to be made in both MPLS-TP and generic MPLS networks.

What “Proposed Standard” means
