1. A method for managing data flows in a Software-Defined Networking (SDN) network, the method comprising:
sending, by a networking device, data packets pertaining to a flow to a SDN controller, upon determining that the flow does not match any flow entry included in a first flow table of the networking device; and
receiving, by the networking device, a flow configuration from the SDN controller,
wherein the flow configuration causes installation of a flooding prevention entry in a second flow table of the networking device based on the network device transmitting a message to the SDN controller, the message comprising one or more header fields of the data packets, the message being free of a payload portion of the data packets, and
wherein the flooding prevention entry enables the networking device to drop subsequent data packets pertaining to the flow until a flow entry matching the flow is installed in the first flow table of the networking device.
