Abstract: Energy consumption is responsible for a large fraction of costs in todays content distribution networks. In upcoming decentralized architectures based on set-top boxes (STB), acting as tiny servers, idle times can dominate distribution cost, since no cooling costs occurs and the Internet access is often paid in a flat-rate manner. The often assumed always-on property provides high availability but might also waste up to 93% of the baseline energy. In this paper we consider suitable standby policies that reduce en- ergy consumption but still allow to offload content servers significantly. We devise optimal and heuristic standby policies and evaluate them in a realistic scenario to show that a near-optimal behavior can be reached by utilizing the specific features of STBs.
