Presentation Transcript

  1. Passive Measurementson the Abilene Jörg Micheel <joerg@nlanr.net> Joint Techs, SLC, UT

  2. Updates since Ohio (July ’04) • Completion of Indianapolis router instrumentation (Nov’04 – Feb’05) • Real time analysis application supporting operational and research requirements • Operational data analysis on IPLS-CHIN since December 2004 (live demo) • lambdaMON prototyping at CENIC/NLR • Passive monitoring getting closer to your network and users – watch this space Joint Techs, SLC, UT

  3. IPLS router instrumentation • All 12 links instrumented • Eight machines: three OC192MONs, one OC48MON, one 2OC12MON, one 2OC3MON, two 2GIGEMON, CDMA time synchronization via Praecis Ct and TDS-24 • Planned to stay there for the lifetime of the backbone • Took 2 ½ years of planning and preparation • Excellent support from Internet2 and Indiana GlobalNOC • Platform for a variety of research works Joint Techs, SLC, UT

  5. Network configuration http://pma.nlanr.net/Sites/ipls-200411/ Joint Techs, SLC, UT

  6. Real Time Analysis • Collaborative effort with University of Leipzig, Germany • Computing about one dozen parameters in real time at line rate, at 10 Gigabit links • Proprietary light weight protocol for data transfer across the network to central archive • RRD based storage/retrieval • Web based user interface, intervals of 5 minutes to one year • Optional JAVA interface • Experimental plug-ins: TCP state monitoring, P2P traffic measurements, IPv6 support, Abilene NMS support • Stress tests during Supercomputing 2004 • Operational trials using IPLS-CHIN since December ‘04 Joint Techs, SLC, UT

  9. Real time during SC’04 (2) Joint Techs, SLC, UT

  10. lambdaMON prototyping (1) • Joint engagement with CENIC and National LambdaRail to build passive monitoring instrumentation for DWDM optical networks • Phase 1 (lab tests) done in October 2004 — successful • Phase 2 (field trial) scheduled for March 2005 at the CENIC Los Angeles node Joint Techs, SLC, UT

  11. lambdaMON prototyping (2) Joint Techs, SLC, UT

  12. Passive Internet Analysis Nodes • Based on the idea of POP instrumentation • Cost effective reconfigurable distributed passive monitoring facility • Service benefits to all US research networks – near ubiquitous • Please come and talk to us if you are interested in collaborating!
