Abstract
A method of monitoring network traffic includes accessing a network that includes a controller and a switch device having a flow table, wherein the controller is communicatively coupled to the switch device, and is configured to program a behavior of the switch device through an openflow protocol, and obtaining information regarding the programmed behavior of the switch device, wherein the act of obtaining the information is performed by a network appliance that is communicatively coupled to the network. An apparatus communicatively coupled to a network, includes a processor configured for accessing the network that includes a controller and a switch device having a flow table, wherein the controller is communicatively coupled to the switch device, and is configured to program a behavior of the switch device through an openflow protocol, and obtaining information regarding the programmed behavior of the switch device.
