With the continuous expansion in scale and the growing Internet application, the sharply increasing electrical consumption of the network has become the bottleneck of the future networks development. Consequently, greening networks comes to the very important issue. Meanwhile, to ensure the scalability and robustness, the network is divided into multiple domains for the distributed routing and management. Therefore, it has become a hot topic on studying the multi-domain green networks. The authors' paper focuses on the power conservation and hybrid grooming in multi-domain IP over WDM networks by means of designing a power- and port-cost-efficient approach.
