1. An application-policy-based Software Defined Network (SDN) controller system, comprising:

  • a first device that is configured to run a first application;

    a second device;

    a physical Software Defined Networking (SDN) network that includes a plurality of physical networking devices, wherein each of the first device and the second device is coupled to the physical SDN network via at least one of the plurality of physical networking devices; and

    a first virtual application-policy-based SDN controller that is associated with the first application and that is provided on a first virtualization device that is not a physical SDN controller device, that is either included in the physical SDN network or coupled to the physical SDN network, and that is part of at least one application communication flow path enabled by the physical SDN network, wherein the first virtual application-policy-based SDN controller is configured to;

    determine a first application communication flow path through the physical SDN network for first application communications that are between the first device and the second device and that involve the first application; and

    provide at least one application-policy-based flow rule to a first subset of the plurality of physical networking devices that are included in the first application communication flow path, wherein the at least one application-policy-based flow rule causes the first subset of the plurality of physical networking devices to transmit the first application communications such that the first application communications satisfy at least one network property.
