优化中小型企业网络的可用性和安全性的设计与部署

AbstractWith the rapid progress of computer technology and the rapiddevelopment of computer networks,the scope of application of computernetwork systems has been continuously expanded,the network system hasalso been huge,and the degree of people relying on computer networksystems is also increasing.Massive amounts of data circulate in the networksystem,and events that cause server crashes occur from time to time,as wellas network security events.Therefore,the most basic traditional performancenetwork system can not meet the needs of the current network systemenvironment.Therefore,the high availability and security of the network hasgradually become the focus of today's network system environment,and thispaper is to optimize the design and deployment of the availability andsecurity of the network system of the majority of small and medium-sizedenterprises.The thesis will use network deployment and topology diagrams tointuitively display the planning of optimized network availability andsecurity networks and all deployments of more complex network systemsinvolved in the thesis.In order to optimize the availability and security of thenetwork system,the main technologies designed and applied are linkaggregation,port bundling,MSTP,gateway redundancy technology,OSPF,firewall HA technology,NAT,IPsecVPN,etc.Usability and security,build anetwork system with both performance and security.Key words:Optimization;High availability;Security;Redundancytechnology;Firewall HA technology
