Enabling the TCP segmentation offload to save energy

Abstract

The aim of this paper is to experimentally evaluate how the enabling of the TCP segmentation offload impacts on the energy consumption of a networked device. To this purpose, we set up a complete testbed that allowed us to perform measurements on energy on a state-of-the-art PC with power management capabilities, and the Linux operating system. From the results we observed that the decrease of the TCP/IP processing in the host CPU allows obtaining an important reduction of the CPU energy consumption.
