The authors propose a distributed approach in which an Internet Service Provider (ISP) and a Content Provider (CP) cooperate to minimize total power consumption. The authors solution is distributed between the ISP and the CP to limit shared information, such as network topology and servers load. In particular, they develop different algorithms adopting dual decomposition and Benders decomposition techniques. They investigate the performance of the proposed solutions on realistic case-studies. The authors compare the algorithms with a centralized model, whose aim is to minimize total power consumption.
