The OpenFlow framework enables flow-level control over Ethernet switching, as well as centralized visibility of the flows in the network. OpenFlow's coupling of these features comes with costs, however: the distributed-system costs of involving the OpenFlow controller on flow setups, and the switch-implementation costs of involving the switch's control plane too often. In this paper, we analyze the overheads, and we propose DevoFlow, a modification of the OpenFlow model in which we try to gently break the coupling between centralized control and centralized visibility, in a way that maintains a useful amount of visibility without imposing unnecessary costs.
