Abstract
A control system for high-speed rule processors used in a gateway system is disclosed. The gateway system employing the current invention can process packets at wire speed by using massive parallel processors, each of the processors operating concurrently and independently. Further, the processing capacities in the gateway system employing the current invention are expandable. The number of packet inspector engines may be increased and all of the engines are connected in a cascade manner. Under the control system, all of the engines operate concurrently and independently and results from each of the engines are collected sequentially through a common data bus. As such the processing speed of packets becomes relatively independent of the complexities and numbers of rules that may be applied to the packets.
