  2. NLANR/MNA • The mission of the NLANR Measurement and Network Analysis group is to study the operation of computer networks, measuring the flow of traffic and analyzing performance issues, to better understand the theoretical and practical behavior of the systems. • Creation of the Network Analysis Infrastructure (NAI) to support measurements and network analysis (within and outside the group) • The NAI consists of two main components PMA and AMP. PMA packet header traces give tremendous amounts of detail at selected points. There are over 130 AMP machines in a full mesh that measure RTT, path, packet loss, and give long-term big scale trend analysis.

  3. Passive Measurement and Analysis (PMA) project • Led by Joerg Micheel • Completely noninvasive, no impact on forwarding paths. • Aggregated traffic signature at a measurement point. • OC3/OC12, ATM and POS, OC48 (develop OC192 capability). • Between June 2000 and Jan 2001 (7 months) 6,000 PMA trace files were downloaded (31 per day) from at least 193 different sites. • Trace analysis summaries include (total packets, Bytes, top port numbers by volume, top 100 throughput connections, etc.)

  5. Active Measurement Project (AMP) • Led by Tony McGregor • Focus on site-to-site measurement across high performance networks • Attempt to deploy FreeBSD-based AMP machines at all HPC sites • about 130 machines currently deployed and operational • RTT, topology, and loss; user/event driven throughput • We currently measure RTT to each of the other monitors every minute and the route to each every 10 minutes

  9. International Collaborations • Discussions with Tom DeFanti have included the monitoring of STAR LIGHT, and early insertion of optical splitters to allow quick installation of PMA machines. • We are in talks with AMPATH regarding the placement of an OC3mon and AMP machine to measure the traffic from AMPATH. • I recently attended a meeting in Russia with Greg Cole of NaukaNet (formerly Fastnet) and are discussing several possible measurement activities.

  10. International Collaborations (Cont’d) • We have a PMA monitor in Israel (soon in Thailand, Germany and Korea), and AMP machines in Korea, Norway, Canada, Australia, Japan and New Zealand (soon Singapore and Brazil). • We are working with Korea, and Australia to help them install their own local AMP meshes. • We are working with the Pacific Rim Applications & Grid Middleware Assembly (PRAGMA) effort at SDSC. • Interest has also been expressed by other countries (Japan, China, Russia, Brazil, Taiwan, Germany, Norway, Mexico, Holland, Switzerland and Thailand) in both the AMP and PMA projects.
