This paper proposes an Improved Particle Swarm Optimization algorithm.IPSO adopts a new mutation operator and a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space.Additionally,this algorithm incorporates a mechanism with a simple and easy penalty function to handle constraint.Thus,this algorithm has strong global exploratory capability and efficiency while being applied to solve nonlinear constrained optimization problems.

At the same time, the anti-attack ability of the system is also improved. Even if some analysis module cannot work, it does not affect other modules. The packet capture module is the base of entire system. At present, most NIDS develop their packet capture module based on libpcap library whose windows edition is winpcap. Allowing for capturing efficiency and self-determined intellectual property and cooperation of each module, we program protocol driver to capture packets. By following methods such as filter in driver and decrease packet copies between user mode and kernel mode, we enhance the capturing efficiency.
