Synonymous Flow Label Framework

Overview

RFC 8957, “Synonymous Flow Label Framework”, is a Proposed Standard document published in January 2021 by S. Bryant, M. Chen, G. Swallow, S. Sivabalan, G. Mirsky. The canonical text is published by the RFC Editor.

Abstract

RFC 8372 ("MPLS Flow Identification Considerations") describes the requirement for introducing flow identities within the MPLS architecture. This document describes a method of accomplishing this by using a technique called "Synonymous Flow Labels" in which labels that mimic the behavior of other labels provide the identification service. These identifiers can be used to trigger per-flow operations on the packet at the receiving label switching router.
