Despite many traffic-engineering-based solutions, very little attention has been paid on performance-guaranteed energy saving schemes. In this paper, we propose a novel energy-saving model for data center networks by scheduling and routing \"deadline-constrained flows\" where the transmission of every flow has to be accomplished before a rigorous deadline, being the most critical requirement in production data center networks.
