VLAN-based Network Model Of Web Server Security And Performance Optimization Research

With the development of network technology, computer use number is increasing. In order to minimize network of fixed assets investment and not to the quality of service decline, from the performance and security of the Web server reliable and efficient work, paper-based VLAN model to resolve the Web server in the security and performance issues.VLAN model of the key issues is the realization of the network and gateway security division, that is, saving IPv4 addresses resources and effective solution network attacks. In this paper, through the VLAN network model of analysis, the use of technology to achieve the three-tier switch VLAN network segment of the division; followed by the ARP attack analysis, research using the normal method of switching network attacks and proposed a multi - Cross-network model, network attacks effective analysis and testing. Through the multi-server model of the existing loopholes and risk analysis for different means of attack is given server security configuration options.The protection of server security, the browser through the use of interpretation and CSS HACK optimization methods and examples, dynamic static page generation technology,. NET cache technology, AJAX technology to achieve a Web server to optimize the performance and achieve application CLUSTER Web server of the NLB CLUSTER, effectively raising the pressure test under the speed of page views. Finally, the development and research work done by summing up, and looked to the future work.
