Abstract
The growing energy consumption has become a major concern for network service providers not only to reduce operational expenses, but also to minimize environmental problems related to the high energy expenditure. In this regard, assessing the energy consumed has become an important task to maximize energy efficiency, and thus, offer different green service levels for customers that desire to save energy. An SDN controller is presented that manages distinct green service levels based on power models to account for the consumed energy and energy saving capabilities. Specifically, we present three SLAs with distinct requirements in terms of energy consumption and models to account for power consumption for each network scenario. Our approach provides a fine-grained accounting of user power consumption in distinct network usage scenarios in order to increase the accuracy of GreenSLA management in next generation networks. The proposal is validated by emulating two use cases inspired on the Facebook topology.
