         MPLS Forwarding Benchmarking Methodology for IP Flows

Abstract

   This document describes a methodology specific to the benchmarking
   of Multiprotocol Label Switching (MPLS) forwarding devices, limited
   to the most common MPLS packet forwarding scenarios and delay
   measurements for each, considering IP flows.  It builds upon the
   tenets set forth in RFC 2544, RFC 1242, and other IETF Benchmarking
   Methodology Working Group (BMWG) efforts.  This document seeks to
   extend these efforts to the MPLS paradigm.
