Abstract
In an example embodiment, there is disclosed an apparatus comprising a first interface configured to receive a packet from a client, a second interface configured to transmit the packet to a server, a third interface configured to communicate with at least one processing device, redirection module in communication with the first interface, the second interface and the third interface, and flow monitoring and state information module in communication with the first interface, the second interface, the third interface and the redirection module. Responsive to receipt of the packet on the first interface, the redirection module is operable to communicate with the flow monitoring and state information module whether state information exists for the packet, the state information comprising an address for a processing device. The redirection module is operable to route the packet to the processing device responsive to determining state information exists for the packet.
