Abstract
A method for balancing load among firewall security devices in a network is disclosed. Firewall security devices are arranged in multiple clusters. A switching device is configured with the firewall security devices by communicating control messages and heartbeat signals. Information regarding the configured firewall security devices is then included in a load balancing table. A load balancing function is configured for enabling the distribution of data traffic received by the switching device. A received data packet by the switching device is forwarded to one of the firewall security devices in a cluster based on the load balancing function, the load balancing table and the address contained in the data packet.
