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?
