All the people named here were directly involved in testing,troubleshooting, and optimizing the links that providenetwork connectivity for this demonstration.
It is certain that others were involved behind the scenesand just as certain that we cannot name them all here.This does not lessen their contribution nor our gratitudetowards them.
Special thanks toRon Roberts of Stanford Universityand J im Warner and MarkBoolootian of UC Santa Cruz,CalREN-2 members who assisted usin troubleshooting
Special thanks toDan Duffy and GaryVeum of the EOSproject for theirtroubleshootingassistance

ConclusionsConclusions What, How, and Where to measure? Many NSF, NLANR, CAIDA, and I2 efforts have
made a good start at a testing infrastructure: Active and Passive Measurement
OCxmon AMP NIMI
Surveyor JPL needs more and better measurement tools
to support Advanced Services JPL needs to understand the tools And then what?
