APPLICATION-POLICY-BASED VIRTUAL SDN CONTROLLER SYSTEM

An application-policy-based SDN controller system includes a first device running a first application, and a second device. Each of the first device and the second device are coupled to a SDN network via one of a plurality of networking devices in the SDN network. A first virtual application-policy-based SDN controller determines a first application communication flow path through the SDN network for first application communications that are between the first device and the second device and that involve the first application. The first virtual application-policy-based SDN controller then provides at least one application-policy-based flow rule to a first subset of the plurality of networking devices that are included in the first application communication flow path. The at least one application-policy-based flow rule causes the first subset of the plurality of networking devices to transmit the first application communications such that the first application communications satisfy at least one network property.
