A NIDS model on network processor

Network processor is a special architecture with parallel processing units and multi-threading to provide high performance. Conventional intrusion detection systems (IDS) are based on software, which limits its detection performance. Now, it proposes to realize these functions by the programmable hardware with high performance such as network processor, which can provide this function and can increase performance even under hostile loads and also will enable efficient intrusion detection in future multi-gigabit networks. It represents the methods and concerns of designing network-based IDS on Intel´s IXP2400.
