Network energy is a significant, although not the largest, cost factor in medium to large scale server installations. On the other hand, most server installations work with redundant link and infrastructure layouts to reduce the risk of network outages. Introducing eBond, an energy-aware bonding network device, we exploit possible heterogeneities in these redundant layouts to adapt network device energy consumption to dynamic server bandwidth demands. Replaying the trace of a realistic scenario in a simulation of eBond with fine grain energy profiles measured at two network cards we achieve energy savings up to 75 % for the server-side network interconnect.

Abstract-Always Best Packet Switching (ABPS) is a novel approach for wireless communications that enables mobile nodes, equipped with multiple network interface cards (NICs), to dynamically determine the most appropriate NIC to use. Using ABPS, a mobile node can seamlessly switch to a different NIC in order to get better performance, without causing communication interruptions at the application level. To make this possible, NICs are kept always active and a software monitor constantly probes the channels for available access points. While this ensures maximum connection availability, considerable energy may be wasted when no access points are available for a given NIC. In this paper we address this issue by investigating the use of an "oracle" capable of providing information on network availability. This allows to dynamically switch on/off NICs based on reported availability, thus reducing the power consumption. We present a Markov model which allows us to estimate the impact of the oracle on ABPS: results show that significant reduction in energy consumption can be achieved with minimal impact on connection availability. We conclude by describing a prototype implementation of the oracle based on Web services and geolocalization.
