Network Intrusion Detection System (NIDS) is an important and practical tool for network security. To guarantee a precise detection the NIDS must detect packets at a wire speed. However, with the recent trend of high-speed networks, the capability of a single NIDS can not meet the speed's demand, resulting in rising of false negatives. To promote the NIDS performance and efficiency, present studies on IDSs for high-speed network monitoring have begun to choose the distributed architecture as an alterative, first suggested by Christopher Kruegel et al. In such a design, the incoming network traffic is disseminated to a pool of sensors, which process a fraction of the whole traffic, reducing the possibility of packet loss caused by overload.
