Abstract
The present invention relates to a method and system for performing deep packet inspection of messages transmitted through a network switch in a Software Defined Network (SDN). Embodiments of the invention include a network switch, a controller, and a firewall in a software defined networking environment. In the present invention, the network switch is a simple network switch that is physically separate from the controller and the firewall. The invention may include a plurality of physically distinct network switches communicating with one or more controllers and firewalls. In certain instances, communications between the network switch, the controller, and the firewall are performed using the Open Flow standard communication protocol.
