Enabling an Energy-Efficient Future Internet Through Selectively Connected End Systems

We offer an initial exploration of the architectural constructs required to support selective connectivity, whereby a host can choose the degree to which it maintains a network presence, rather than today’s binary notion of “connected” or “disconnected”. The driver for our thinking is to allow hosts to go to sleep to Proposed architectural elements We can view end systems as having three basic states: on, off, and asleep, where asleep reflects a voluntary form of off for which end system can prepare and is willing to forgo or be awaken from if need be. To support this we explore: realize energy savings while not sacrificing their entire standing in the network.
