Design and Implementation of Packet Classification in Gigabit Firewall Based on IXP2400
基于IXP2400千兆防火墙包分类算法的设计与实现

This article focuses on packet filtering firewall used on gigabit network and presents a packet classification algorithm called HSBIPG(Hash Search Based on IP Group).Then we analyze advantages and disadvantages of this algorithm. Finally, we implement a line rate gigabit packet filtering firewall using this algorithm on IXP2400 network processor and it proved to be feasible and efficient by experiment.
