SC2004 Bandwidth Challenge Collection |
|
|||
During Supercomputing 2004 we used the opportunity to demonstrate and evaluate the capabilities of the PMA OC192MON system under various conditions, the highlight of which was to monitor and observe a number of contestants of the Bandwidth Challenge. We were supported by colleagues from Internet2 and NCSA as part of SCinet. We operated the OC192MON from Monday November 8th through to Thursday November 11th, 2004. Most of the time the OC192MON was collecting and analyzing data in real time; with one major gap between Tuesday night and Wednesday morning, during which the system was collecting IP packet header trace data - this data set. The OC192MON was initially tuned into the Abilene link towards New York (see also the weathermap). This configuration was changed on Tuesday night, after which the system was observing the Abilene link to Chicago, until it was turned off on Thursday afternoon. All times are Eastern Standard (Pittsburgh, PA, local time). This data set is attractive for researchers wishing to explore high bandwidth long duration data flows (also called elephants). We will be publishing graphs shortly. Data is available at the following locations: References

for their help and support prior and during SC2004 in setting up the taps
and fibers as well as providing details on the configuration of the network
links observed.
