Design And Implementation Of High-performance Security Switches

With the development of the application of computer network, network security has become an important problem which is attracting more and more attention. It is the researchers' urgent task who focus on network security to find out the principle of attack and intrusion, and provide the corresponding solutions to network security.This article first simply discusses the problem of the principle and the defending mode of network security. Then it introduces some popular secure methods, such as Firewall, Identification and Authentication, data encryption. At last it raises the conception of the high performance secure switch.Base on the BCM5600 chip, the high performance secure switch has the ability of layer 3 switch,resolve the bottleneck problem of data transmitting due to the router connect the subnets.At the same time, the ability of layer 3 switch make it easy to capture data in the layer of IP,and realize the ability of Intrusion Detection.After deeply researching the technologies of layer 3 switch and Intrusion Detection,we present the design scheme of high performance secure switch.
