Augmenting Network Interfaces to Reduce PC Energy Usage
Source: University of California
Reducing the energy consumption of PCs is becoming increasingly important with rising energy costs and environmental concerns. Sleep states such as S3 (suspend to RAM) save energy but prevent the PC from responding to network traffic, for example remote desktop logins, file transfer requests, or content distribution protocols such as bittorrent. Authors conducted a background survey showing that having these applications running is the reason why many users leave PCs on even when idle. Authors present Somniloquy, an architecture that augments network interfaces to allow PCs in S3 to be responsive to network traffic, transparently to remote applications and to the network itself.
