A function-parallel network firewall is a scalable architecture that consists of multiple firewalls. Rules are distributed across the array such that each firewall implements a portion of the original policy. This resutls in significantly lower delays than other parallel designs; however, the design requires firewall intercommunication to coordinate the array which is difficult to implement and introduces additional delay. This paper describes how the performance of a function-parallel firewall
more &raquo; ... array can be increased if the individual firewalls can operate independently, without firewall intercommunication. By distributing rules using accept sets, the independent firewall array and a traditional single firewall will always arrive at the same decision (integrity is maintained). Simulation results will show the system is significantly faster than other designs and has the unique ability to provide service differentiation.
