Abstract
The purpose of this document is to describe methodology specific to
the benchmarking of multicast IP forwarding devices. It builds upon
the tenets set forth in RFC 2544, RFC 2432 and other IETF
Benchmarking Methodology Working Group (BMWG) efforts. This document
seeks to extend these efforts to the multicast paradigm.
The BMWG produces two major classes of documents: Benchmarking
Terminology documents and Benchmarking Methodology documents. The
Terminology documents present the benchmarks and other related terms.
The Methodology documents define the procedures required to collect
the benchmarks cited in the corresponding Terminology documents.

1. Introduction
This document defines tests for measuring and reporting the
throughput, forwarding, latency and Internet Group Management
Protocol (IGMP) group membership characteristics of devices that
support IP multicast protocols. The results of these tests will
provide the user with meaningful data on multicast performance.
A previous document, "Terminology for IP Multicast Benchmarking"
[Du98], defined many of the terms that are used in this document.
The terminology document should be consulted before attempting to
make use of this document.
This methodology will focus on one source to many destinations,
although many of the tests described may be extended to use multiple
source to multiple destination topologies.
Subsequent documents may address IPv6 multicast and related multicast
