| The flow of streaming media and file transfer application data are increasing in the current power information and communication network.If the data servers are still deployed in one place,the concurrent requests of users will not only challenge the performance of the server,but also reduce the quality of service to the users.By deploying power CDN network,the source station contents are distributed to every edge nodes,which allows users to access the nearest edge nodes and obtain the required resources from them,thus reducing the amount of access to the source station,relieving the pressure of the source station and improving the response speed of the website.In order to control the information of every network elements in the power CDN network,a network management system is needed to meet the requirements of the power CDN control,so as to realize the overall management of the various network elements in the power CDN network.Firstly,this article analyzes the demand of CDN technology in electric power communication network,and studies the necessity of network management's realization in power CDN network.Then,the overall architecture of the power CDN network management system is designed by analysing the demand of the system.Also,the overall system security scheme is designed for the protection requirements of the power secondary system.Subsequently,the six management modules of the network management system are designed based on Web technology.Because of the high demand of timeliness of performance data in the power CDN network,the function process design of the performance management module is carried out under the premise that the performance data acquisition occupies less computing resources.At last,the interface of the six functional modules of the power CDN network management system is designed and displayed,and the real-time monitoring and management function of the power CDN network is realized.In summary,this article has a certain practical value in engineering. |
