  1. Traffic Management Benchmarking Framework IETF 86 Orlando Barry Constantine barry.constantine@jdsu.com Tim Copley timothy.copley@level3.com Ram Krishnan ramk@brocade.com

  2. Traffic Management Benchmarking Overview • Could be an extension of RFC 2544 benchmarking into traffic management functionality • Classification / Prioritization • Policing • Buffering • Queuing / Scheduling • Shaping • In addition to packet based testing, would utilize “application test patterns” in order to fully characterize the performance of the device under bursty traffic conditions

  3. Status of Personal Submission • Received extensive comments from three (3) reviewers • Overall comments were very supportive of this work • Summary of comments: • Test the DUT with multiple flows during each of the test types; for example, queue tests need each type of queue exercised in parallel • In addition to observed packet performance (i.e. drops), verify that the DUT counters are accurate • Need to address multiple port test cases • Add TCP layer testing to the Policer benchmarking (in addition to stateless traffic tests) • Remove the misused “QoS” term throughout document

  4. Discussion of Benchmark vs. Functional Test • Al Morton made some comments (as chair) concerning the nature of a functional test versus black-box benchmark • “Inherently, that testing includes the "functional" test that you are seeking now (If I configure 64kbps CBR, does the DUT enforce/achieve that limit)” • Language in the draft will be augmented to align with the BMWG charter • Clearly state that performance metrics will be measured to compare vendor performance

  5. Next Steps for the Traffic Management Draft • We seek the BMWG to formally adopt this personal submission as a chartered draft work • Work intensely on the next revision(s) to incorporate the excellent comments that we received
