  • 2. Passive Measurement and Analysis (PMA) project <ul><li>Completely noninvasive , no impact on forwarding paths </li></ul><ul><li>Aggregated traffic signature at a measurement point </li></ul><ul><li>OC3/OC12, ATM and PoS </li></ul><ul><li>Between June 2000 and Jan 2001 (7 months) 6,000 PMA trace files were downloaded (31 per day) from at least 193 different sites. </li></ul><ul><li>Trace analysis summaries include (total packets, Bytes, top port numbers by volume, top 100 throughput connections, etc.) </li></ul>(Passive traffic collection and analysis at optical carrier speeds)

  • 4. Internet Trace User Community <ul><li>Led by Joerg Micheel </li></ul><ul><li>We are seeking constructive discussion on monitor placement </li></ul><ul><li>strategies, trace duration, trace variety, etc. </li></ul><ul><li>For example, a number of researchers have requested longer duration traces. As a result, a set of passive traces from Auckland that consists of single and multiple day duration traces were made available. Researchers have published at least 7 papers based on those traces. </li></ul><ul><li>Which PMA trace summaries are most helpful in allowing other researchers to choose from available trace data sets? </li></ul>
  • 5. Active Measurement Project (AMP) <ul><li>Led by Tony McGregor </li></ul><ul><li>Focus on site-to-site measurement across high performance networks </li></ul><ul><li>Attempt to deploy FreeBSD-based AMP machines at all HPC sites </li></ul><ul><ul><li>about 120 machines currently deployed and operational </li></ul></ul><ul><li>RTT, topology, and loss; user/event driven throughput </li></ul><ul><li>We currently measure RTT to each of the other monitors every minute and the route to each every 10 minutes </li></ul>
