The Network security systems have become is necessary for our society in recent years, and one of being URL Filtering devices. Now, the way of Filtering processing with software is currently the most popular. This method produces some results, but processing time is slow, so in the coming era of 10 Gbps, it is impossible to handle, even using the fastest CPUs (microprocessors). Certainly, this method is useful and widely common. However it takes a lot of time if we used in this method, so it is not possible to correspond to CPU of the highest processing performance in the time of 10 Gbps.

Thus in this paper research and development, we proposed investigated the method of the super high speed pattern match processing circuits, and made an experimental network URL filtering system for 10 Gbps .As a result, this system’s throughput was up to 1.6 Gbps even if it have received in the worst case of receiving continuous minimum length packets that is worst case. In addition, it is achieved 6.0 Gpbs when receiving throughput was up to 6.0 Gbps when this system received continuous maximum length packets.
