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.

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.)

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

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.

International Collaborations (Contd)

• 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.
