接入网综合网管采集接口技术分析

Analysis on integrated network management acquisition interface technology of access network

接入网是城域骨干网业务接入控制点以下的二层接入网络,包括:DSLAM设备、LAN设备(汇聚交换机及接入交换机)、PON设备、MSAN设备及WLAN设备等。随着"光纤入户"、"宽带提速"和"三网融合"等一系列政策战略的推进,为了实现集约化管理的方针,需要一套面向整个接入网的综合网管系统,实现包括拓扑管理、配置管理、故障管理、性能管理、资源管理、测试诊断、安全管理、系统管理、运行分析、业务自动激活等功能。文章结合目前最新的分布式技术、数据库技术、采集技术及中国电信集团相关规范对接入网综合网管的采集接口及测试技术进行研究。

Access network is the second layer network of the metropolitan area network service access control points, including DSLAM equipment, LAN equipment （aggregation switches and access switches）, PON equipment, MSAN equipment and WLAN equipment, etc. With the development of ＂fiber-to-the-home＂, ＂broadband acceleration＂ and ＂triple play＂ and in order to achieve the intensification management, a set of integrated network management system for the access network is needed to realize the functions of topology management, configuration management, fault management, performance management, resource management, testing, diagnosis, safety management, system management, operation analysis and business automatic activation. Combining with the latest distributed technology, database technology, acquisition technology and the relevant specifications of China Telecom Group, this paper studies the acquisition interface and testing technology of integrated network management of access network.
