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

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

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

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

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!
