RFC6374 Synonymous Flow Labels
draft-ietf-mpls-rfc6374-sfl-10
Abstract
RFC 6374 describes methods of making loss and delay measurements on
Label Switched Paths (LSPs) primarily as used in MPLS Transport
Profile (MPLS-TP) networks. This document describes a method of
extending RFC 6374 performance measurements 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 multi-point to point LSPs and introduces some additional
techniques to allow more sophisticated measurements to be made in
both MPLS-TP and generic MPLS networks.
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
