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.

This document is a product of the Multiprotocol Label Switching Working Group of the IETF.

This is now a Proposed Standard.
