NLANR/MNA Measurement and Network Analysis

NLANR/MNA aims to create a Network Analysis Infrastructure (NAI) to support measurements and network analysis, including header traces, performance statistics, tool development, and research activities. All data, analyses, graphs, and tools are made publicly available. The project also includes an Internet Trace User Community and active measurement project.

  2. Goals and objectives • Creation of the Network Analysis Infrastructure (NAI) to support measurements and network analysis • header traces, performance, statistics • Network measurement and analysis research activities • Tool development for analysis and visualizations • All data, analyses, graphs, visualizations, and tools are made public available for use by all researchers.

  3. Public Interface • Internet Trace User Community • Attendance and presentation at meetings • Host PAM2003 Workshop. • Result reporting for the high performance environment • Web interface • newsletters (Networking Analysis Times, Packets) • published papers

  4. NLANR/MNA Publications • 2002 - 5 • 2001 - 12 • 2000 - 8 • 1999 – 7 (28/32 were peer reviewed) • PAM2002 3/18 papers, 1/3 posters • http://moat.nlanr.net/Papers

  5. Internet Trace User Community • Led by Joerg Micheel • We are seeking constructive discussion on monitor placement • strategies, trace duration, trace variety, etc. • 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. • Which PMA trace summaries are most helpful in allowing other researchers to choose from available trace data sets?

  6. Passive Measurement and Analysis (PMA) project (Passive traffic collection and analysis at optical carrier speeds) • 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.)

  16. Event Detection • Tony McGregor • AMP system consists of around 130 monitors in a full mesh. A set of graphs is available for each of the approximately 14,000 measured paths. • The Automated Event Detection is a system for detection of events in data collected by active monitors. • The system is divided into algorithms; each algorithm detects one class of network event. Currently, three algorithms are implemented. The "Plateau Detector" detects a change in the base RTT between a pair of monitors. A second algorithm detects a change in the RTT variance over a path. While the last algorithm triggers when packet losses are above an input threshold value.

  17. Collaborations • Internet2 • 1. regarding the IPLS router instrumentation at the Indiana GigaPOP (Joerg Micheel in discussions with Matt Zekauskas). • 2. continuing discussions with I2 researchers regarding AMP involvement in E2E project (Tony McGregor, Ronn Ritke). • 3. participation on the Internet2 End-to-End Performance Initiative Design Team (Ronn Ritke). • Deployment of AMP machines at NASA Goddard and JPL. The machine at JPL is part of the JPL Performance Reference System. • We now have AMP monitors at LBNL, SLAC, Argonne National Lab and Fermi DOE facilities.

  18. Collaborations (Cont’d) • Phil Dykstra and Cindy Dykstra, WareOnEarth (WCI, Inc.) • regarding the AMP peer network with Defense Research and Engineering Network (DREN), as well as other activities. • Other NLANR sites and their researchers and administrators, including weekly conference calls, and other activities. • Kevin Walsh and Jay Dombrowski network systems group at SDSC (SDSC Enterprise Network Services [ENS]) on creating the data compute engine/repository containing a replica of AMP data, as well as additional activities.

  19. 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 OCXmon and AMP machine to measure the traffic from AMPATH. • We are in contact with Greg Cole of FASTnet (formerly MIRnet) and are discussing several possible measurement activities.

  20. International Collaborations (Cont’d) • We have a PMA monitor in Israel, and AMP machines in Korea, Norway, Australia, and New Zealand (soon Japan). • We are working with Canada, 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 and Thailand) in both the AMP and PMA projects.
