What is it about?
The Linux operating system provides many well-developed tools that support the concept of energy-efficient networking. This paper outlines the results of research focused on the design and implementation of a control system reducing power consumption of IP-traffic processing in a network of Linux-based software routers.

Why is it important?
It is demonstrated how the standard ACPI-compliant system components can be adjusted to meet the requirements of adaptive energy-aware network control and what performance trade-offs may there be expected. In particular, it is demonstrated how the abstraction layers provided by the Linux kernel can be used to exploit energy-saving mechanisms of packet processing servers. Formulations of the routing optimization and service rate control problems are presented and discussed. The results of the extensive experimental studies are presented as well.
Perspectives
This work summarizes the research we conducted within the ECONET project. An experimental network control system is presented that allows to optimize energy consumption of Linux-based routers performing real-time packet inspection operations.
