| At first, the system structure of EPON network and the network management system architecture are analyzed in this paper. On this basis, the demand of EPON performance management is studied in details to further discuss the key technologies to construct the system, which are the research of network management protocol and the selection of performance prediction algorithm. With the whole system structure in mind, the J2EE and MVC mode is adopted to design and realize the three functional module:current-performance management module, history-performance management module and forecast-performance management module. According to the data characteristics of EPON network performance indexes, the thought of mixed forecast mode based on the improved moving average forecast model, second exponential smoothing model and gray model, is put forward. And then the detailed design and specific implementation of the model are introduced. Finally, the backend database module is designed to combine the design of tables with the table management, which greatly reduces the data redundancy, enhances the data sharing efficiency. Thus, the efficiency of mass data management is achieved in the system.The performance management system for EPON based on web is designed and implemented in this paper. The network performance data is collected and analyze to provide statistic proof for further planning and adjustment of the network, so that the network service quality become better. Meanwhile, the mixed forecast model is adopted to effectively reduce forecast error and strengthen the correctness of performance forecast. It's indicated that the EPON network performance network become intelligent. In addition, comparing with the Client/Server, the Browse/Server structure adopted in the system greatly simplifies the client, because the development and maintenance is conducted in the server. |
