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
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

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
lambdaMON prototyping (2) Joint Techs, SLC, UT
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!
