Title: Passive Measurements on the Abilene


1
Passive Measurements on the Abilene
  • Jörg Micheel
  • ltjoerg_at_nlanr.netgt

2
Updates since Ohio (July 04)
  • Completion of Indianapolis router instrumentation
    (Nov04 Feb05)
  • 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

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

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!
