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.
