Abstract
Mechanism for implementing energy efficiency (EE) policies on flows in a software defined network are disclosed. A controller node receives from each of a plurality of datapath nodes, a corresponding set of EE actions that the respective datapath node is capable of implementing. A flow is identified, and a group of datapath nodes through which the flow is routed is identified. Based on an attribute of the flow, an EE policy is determined. Based on the EE policy, a datapath node in the group of datapath nodes is directed to perform an EE action on packets associated with the flow.
