RFC6374 Synonymous Flow Labels
draft-ietf-mpls-rfc6374-sfl-02
Abstract
This document describes a method of making RFC6374 performance
measurements on flows carried over an MPLS Label Switched path. This
allows loss and delay measurements to be made on multi-point to point
LSPs and allows the measurement of flows within an MPLS construct
using RFC6374.
