Research for Network Fault Real-time Alarm System Based on Pushlet

Network fault real-time alarm system as part of network fault management, is responsible for collecting and storing the fault information, then distribute the fault information to administrator. In process of alarm information distribution, network management system need to implement a real-time data transfer mode, which is a server push technology. The traditional work model of HTTP is a pull technology. This model is characterized by client making request and server-side response. With the fast development of HTTP, asynchronous transfer and TCP persistent connection have bean widely used in the web Application. But these technologies for real-time transmission of information have still many problems and disadvantages. In this article network fault real-time alarm system combines pushlet framework with CORBA technology, to implement a server push model based web. Compared with other technologies, it has advantages of better adaptability, versatility, and security.
