Abstract
Methods and systems for balancing load among firewall security devices (FSDs) are provided. According to one embodiment, a switch maintains session data the session entries of which represent established traffic sessions between a source and a destination and form an association between the traffic session and a particular FSD. A data packet of a traffic session from a client device directed to a target device is received at the switch. When none of the session entries are determined to correspond to the data packet, an FSD is selected to associate with the first traffic session by performing a load balancing function on at least a portion of the data packet. When a matching session entry exists, an FSD identified by the matching session entry is selected to process the data packet. The data packet is then caused to be processed by the selected firewall security device.
