The Design And Implementation Of Network Core Basic Service System For Weihai Power Supply Company

With the increase in the business of Weihai power supply company,a large number of new business systems have been gradually on the line,customers in the past using the client through the form of IP access to business systems is no longer applicable,in this way,the migration of the application system requires the server or the client to modify the IP parameter configuration,which requires a lot of manual operation and greatly limits the flexibility of the application deployment.Due to the networking of Weihai power supply company's business system and the gradual centralization of data,the computer network has become the center of information transmission and data exchange.Based on the above reasons,Weihai power supply company designed and implemented the network core basic service system.The network core basic service system chooses to use B/S architecture,JAVA language,through the page for functional access,using MVC ideas,technical framework is JFinal framework.The client of network core base service system sends an Http request,the request is stored in the Request request,and the JfinalFilter intercepts all requests,via the Handler processor,calling the Actionhandler.Actionhandler creates the ActionInvocation action scheduler,then uses the interceptor's Controller Method to render,returns the Response request,and responds to the client through the Http.The network core basic service system implements four functions,such as the IP address management,the IP address audit,the IP access configuration,the network equipment configuration.The function of IP address management implements the IPv4 network configuration,IPv6 network definition,MAC address management,network usage analysis,IPv4 fixed address view,IPv6 fixed address view,shared network identity management.The function of IP address audit implements DHCP distribution history audit,address change audit,query dynamic authorization data and query IPv4 address information.The function of IP access configuration implements the system related configuration,authorization,and release of authority.The function of network device configuration implements the creation of new network equipment items,network equipment add scripts,script task customization and running examples.The application of the system can automatically and effectively manage the IP/MAC resources of the access network,provide updated data in real time,control the unauthorized IP/MAC address to access the network,and realize the efficient analysis of the DNS domain name,thus improving the security of the internal network.
