Abstract
A Secure cluster-based Server System includes a plurality of firewalls, a plurality of back-end Servers, a logically external firewall dispatcher, a logically internal firewall dispatcher, and a plurality of Second Stage dispatchers. The external firewall dispatcher is configured for routing packets received from the external network through one or more of the firewalls to the internal firewall dispatcher, the internal firewall dispatcher is configured for dispatching packets received from the one or more firewalls to one or more of the Second Stage dispatchers, and the Second Stage dispatchers are configured for dispatching packets received from the internal firewall dispatcher to one or more of the back-end Servers for processing. A computerized method of interfacing an external network to a cluster-based Server includes receiving packets from a plurality of firewalls with a first Stage dispatcher, dispatching each received packet from the first stage dispatcher to one of a plurality of Second Stage dispatchers, and dispatching each packet received by one of the Second Stage dispatchers to one of a plurality of Servers for processing.
