Network definitionGeneral simple architecture defined during HSSG Tutorial 07 – update?

“Silo Lingo” should not prevent communications!

Need data that demonstrates bandwidth usage / forecast“Wish list” input should be separated from evaluation of data

Network Aggregation will be driven by end stations – status of computing applications?

Questions to Ask?Time frame?

How far back – historical trends?How far forward?

Data or wish list?

Others to contact?
