Web System Design And Implementation For Cvit Campus Network

In the rapid development of network management technology today, alongwith some network protocols and application of new technologies, in order toimprove network efficiency and reduce network failures, it is necessary toestablish a stable and efficient network management system. For the campusnetwork, it is to ensure the safety of the daily work of teachers and students thekey safety system consists of firewall, VPN, QoS and security products, suchas the composition of a number of technologies have become the main meansto solve the problem. Web-based technology security system systemavailability due to the command can be solved with the tedious, complicatedconfiguration parameters causes, applicability, ease of use issues in order toachieve the icon of the intuitive system configuration to achieve user-friendlyinterface, easy to use, quick eye and many other advantages. Therefore, thispaper, the actual situation and needs of Changchun Vocational and TechnicalCollege campus network, Web-based technology for the construction andimplementation of network security system.This paper describes the background of Changchun Vocational andTechnical College, significance and status of research campus networksecurity system and the characteristics and applications of Web technology,and then the whole system will be explained on the platform and publicfunctions. Again this basis, a detailed description of the design andimplementation of the Campus Network Web systems. Web system designedCCP modules of ten, I mainly responsible for the firewall, QoS, and systemmonitoring design and development of three modules. In the Firewall module,since many configurations need to bind a configured packet classification rules to take effect, if the user configure these parameters when they would go backto the page to see packet classification parameters, it is inconvenient for thisproblem, using ajax partial refresh without flash technology to achieve thedesired purpose, users only need to select the packet classification rulesbinding, packet classification rules in the selected page will refresh thefollowing rules specific parameters. There are many references to the addressconfiguration can be an object or group of objects such as address, but afterconfigured to display only if the object name, object-specific information seethe system ’s ease of use will have an impact, for such problems, prepared aseries of public function, when the user clicks the hyperlink object name, thespecific configuration of the object will pop up a dialog box. In the QoS modulefor demand, out of consideration of the structure clear, at design time using atree structure, namely the interface is the root, which for five kinds of QoSfunction interface is five children, and each function parameters asgrandchildren. In the function module wfq, adding the congestion avoidancewred settings. In the function module hsq in demand because of its specificity,resulting Web page reflects very difficult, and ultimately the Add button andpass through two parameters ingenious solution to this problem. Systemmonitoring module, due to the real-time monitoring parameters are changing,so it needs to periodically refresh the page, through the understanding of ajaxtechnology, based on ajax technology, adding a simple piece of code, toachieve the pages regularly updated. While applying gdchart technology toachieve a graphical display of system parameters.
