Web-based Network, Real-time Monitoring

The Web-based distributed monitoring system displays the real-time information of the enterprise control system on the remote BrowserBased on the analysis of the architecture of the Internet-based monitoring system and dealing with the real-time data of the monitoring system, the design of real-time monitoring Web data gateway is introduced in this paper. The Web data gateway is implemented by the multi-thread. It gathers the real-time data of the control system and sends the data to the remote browser. The real-time data is displayed dynamically on the browser. The Web data gateway has the good function of the management and the service of the requirements of the Web pages and the users, and data objects.At the same time, the system has flexible structure.In the end, the recovery of the distributed main memory database is discussed in the thesis , including: dump^ distributed transaction commitment and log . In the end the thesis gives a log producing algorithm , which aims at the application under the distributed environment , improving on the 2-Phase-Commitment Protocol. It has a good future to apply.
