The Design and Implementation of the High Speed Firewall Based on Networks Processors LIU Wei12, CUI Yong-feng2 (1.Control Science Engineering Department, Huazhong University of Science Technology ,Wuhan,China 430074; 2.Network Centre, Zhoukou Normal University, Zhoukou,China 466000) Abstract: At first,this paper introduced two kinds of design mentalities of the high speed firewall ,after the contrast, design the firewall based on the network processor. Then elaborated the system structure and the system frame of this firewall, and give a brief introduction of the network processor model, the control level design which as an important of the firewall,also has the detailed introduction, finally has produced this firewall test result.
