EPON网管系统通信接口回调功能的设计与实现
首发时间:2009-01-12
摘要:EPON网络管理系统客户端需要实时监视设备告警、设备性能数据。网管客户端获取这些实时数据的方式一般有两种,一种是主动取值方式,一种是回调方式。主动取值方式需要不停的轮询服务端,会导致进行其它访问操作时效率低下、速度减慢,显然这种方式不适合告警数据和性能数据传输。 本文提出了一种基于JAVA语言的EPON网管系统通信接口回调功能方案。此方案在EPON网管系统中得到了很好的应用。业务逻辑开发人员无需关心通信问题,可以集中精力在业务逻辑的开发上。同时,RMI通信接口又为业务逻辑开发提供强有力的支持。回调功能被用于同步处理中,大大降低了系统中各个模块的耦合性。具有回调功能的EPON网管系统使告警、性能数据传输性能更高。同时采用回调功能,每个客户端的数据保持同步。

EPON network management system communication interface callback function design and implementation
Abstract:The clients of EPON network management system need surveilancing the alarm and performance datas at times . Two methods can be used to get these datas , initiative method and callback method.With the initiative method ,the client needs call the server no-stopping.This method will decrease other operations .This method is not suitable for transmiting alarm and performance datas. In this paper the authors introduce a new method of EPON network management system communication interface callback function design and implementation;this method is based on JAVA.This method has been used in the EPON network management system..With this method ,the members in the project can focus on the project developing and need not to take care of the communication of the system .At the same time , the RMI communication interface gives the development of the project a good hand. In the Callback function , the server upword transmit real-time data initiatively. This method is nimble ,highly effective and initiative .It can be used to synchronize the client’s data and reduce the server’s load.
Keywords: Communication Interface CallBack alarm upword transmit EPON network
