Method:
-Global approach applied to network, servers and clients.
-Internet based, Internet compatible.
-Time modeling of traffic, active cyclicization and scheduling, power control during predictable “rest” periods.
-Definition of requirements for systems and components.
Less Components -> Less Power
More Sleeping Periods -> Less Power
