MPLS Working Group S. Bryant (Ed) Internet-Draft Futurewei Technologies Inc. Intended status: Standards Track G. Swallow Expires: August 14, 2021 Southend Technical Center M. Chen Huawei G. Fioccola Huawei Technologies G. Mirsky ZTE Corp. February 10, 2021 RFC6374 Synonymous Flow Labels draft-ietf-mpls-rfc6374-sfl-09 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 making RFC 6374 performance measurements on flows carried over general 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 general MPLS networks.
