What is sleep server ?

Sleep Server is a Software-Only Approach

for Reducing the Energy Consumption of PCs within

Enterprise Environments

wHy sleep server concept ?

Energy consumption of ICT.

Global ICT CO2 emission.

How does it work?
Goals to achieve:
The proxy must be able to maintain the network presence of any host on the local network while maintaining complete transparency to other end hosts in the network and to network infrastructure elements such as switches and routers.

Since the proxies themselves add to the total power consumption, they must be highly scalable.

The proxy should be able to provide isolation when it is servicing individual hosts while providing mechanisms to scale resource allocation based on the proxying demands of individual hosts.

The proxy must address management aspects, such as providing mechanisms to enable and disable the proxying functionality for hosts dynamically.
The proxy should be able to support a heterogeneous environment with different classes of machines running different operating systems.

We have to achieve all of the above goals
purely in software without requiring any additional hardware to the individual end hosts
