Push技术在基于Web的网络管理中的应用

Push技术作为第三代浏览器的核心技术，是一种客户机/服务器之间的通信方式，它采用了公布/订阅/行结构，因而对其应用非常广泛。基于Web的网络管理系统采纳Push技术后，与传统的请求／响应模式相比，效率高，时延低，并且可以节省带宽和CPU时间。而且，对于告警信息的及时上报有重要意义。文中提出了基于Web的TMN管理实例，并在此基础上探讨了应用Push技术实现告警功能的方法。

Application of Push technique in web-based network management system

As the kernel technique of the third generation browser,PUSH model that relies on publishing/subscribing/distributing paradigm is a kind of communication mode between client and server. The method to apply PUSH technique in web-based network management system is advanced. Contrast with conventional request/response model,it has advantages of high efficiency and low time delay,and it allows administrators to save network bandwidth and CPU time on the management station. Furthermore,it is important for the client to acquire alarm information in time. An example of Web-based TMN is introduced,and based on this example,the method of applying PUSH technique to achieve alarm function in the TMN is discussed too.
