A New Web Services Model Based on CORBA and Push Technology in Network Management System

Because the traditional network management model based on Web and CORBA which adopts pull technology can not obtain info actively and in time, this paper put forward a new Web services model based on CORBA and push technology in network management system, which combines information push technology with CORBA notification service. This model changes the passive status of server and implements network management in an active style. It can push the trap information to manager actively through the TCP connection established when logging in. Compared with the traditional Web and CORBA based network management model, it has advantages of high efficiency, low time delay, and can save network bandwidth and CPU time. Furthermore, it is important for the manager to acquire alarm information in time.
