  1. BMWG Meeting Maastricht July 2010 Mike Hamilton mhamilton@breakingpoint.com BreakingPoint Systems Content-Aware Device Benchmarking Methodology(draft-hamilton-bmwg-ca-bench-meth-04)

  2. Agenda • Why draft-hamilton? • Charter objections/responses • Goals reset • Explicit goals of this draft • Explicit non-goals of this draft

  3. Why draft-hamilton? • RFC 2544 doesn’t specifically apply to some modern devices • Test vendors are already doing this in a one-off fashion • BreakingPoint, Spirent, Ixia, Agilent, etc.

  4. Charter Objections • “the scope of the BMWG is limited to technology characterization using simulated stimuli in a laboratory environment.” • “Said differently, the BMWG does not attempt to produce benchmarks for live, operational networks • This does not restrict BMWG from creating benchmark tests that are representative of VERY SPECIFIC live, operational networks

  5. Goals Reset • Create a series of benchmark tests to MOST accurately predict device performance under realistic conditions FOR A SPECIFIC SIMULATED NETWORK • RFC 2544 Quotes Page 11, Section 18, “Multiple Frame Sizes” • “The distribution MAY approximate the conditions on the network in which the DUT would be used.” • “The authors do not have any idea how the results of such a test would be interpreted other than to directly compare multiple DUTs in some very specific simulated network”

  6. Explicit Goals • Repeatable Results • Compare Multiple DUTs

  7. Explicit Non-Goals • Not a replacement of RFC 2544 • Total Input Repeatability (discussion to follow)

  8. Test Run Setup • Methodologies Run • RFC 2544 Throughput (64B + 1518B) • RFC 3511 Throughput (1 kB + 512 kB) • IMIX Throughput • CAIDA • Spirent • Wikipedia • Agilent-simple • draft-hamilton-03 (random) • draft-hamilton-04 (shell)

  9. Test Results

  10. Fuzzing Results

  11. Draft-04 Highlights and Reasons • “Shell” Methodology • More reproducible • Backoff on ‘realistic’ • Compromise • Dropped ‘security’ • Difficult to scope and maintain currency • Maintain ‘fuzzing’ aspect • Random but repeatable
