面向三网融合的综合网管系统的设计与实现

摘要

三网融合后网络规模的扩大、设备数量和种类的增多,给网络管理的建设带来了很大的挑战.文中设计并实现了一个面向三网融合的综合网管系统,给出了系统的总体框架,以及解决网络规模大和设备数量多的问题采用的关键技术及方法,为解决融合后的网络规模大、设备类型多样化和信息海量的管理问题,关键技术主要包括适应各种类型设备管理的通用网管协议转换模型、提高数据采集速度的基于广播的数据采集算法和增量式告警信息刷新方法.对已开发的实际系统的测试结果表明,文中的综合网管系统可以对三网融合后网络中的设备进行有效的管理,与传统的网管相比较在通用性、数据采集效率和实时性方面都有了很大的提高.%After the expansion of triple play network, the number and types of devices increase, so the construction of the network management is a big challenge. It presents the design model and its implementation of an integrated network management system for triple play. In order to solve the problems of large network scale, various types of device and massive information brought by the triple play, the key technology issues and solutions are also given. The three key technology issues include a common network management protocol conversion model to capture the running information of different types of equipment,a broadcasting-based data acquisition algorithm to improve the acquisition speed, and an incremental approach to refresh alarm information in real time. The test results show that the integrated network management system which developed can effectively manage various types of equipments in triple play network and the applicability, efficiency of data collection and real-time of system are greatly improved compared with raditional network management systems.
