ABSTRACT:
Firewall sandwich configurations having improved levels of system availability as well as an application-space implementation of a firewall load balancer (FLB) which provides greater operational flexibility while reducing the need for custom hardware and/or operating system software. Also disclosed is a firewall capable of functionally replacing an FLB upon detecting a failure therein.
