Conclusions
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
2000-12-04
OCxmon
AMP
NIMI
Surveyor
JPL needs more and better measurement
tools to support Advanced Services
JPL needs to understand the tools
And then what?
