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 |
Slide 4
Network configuration
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 |
|
|
Slide 7
Real time during SC’04 (1)
Real time during SC’04 (2)
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 |
lambdaMON prototyping (2)
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! |
