摘要
随着网络技术的迅猛发展,网络稳定、高效、准确的运行显得极为重要。因此,
必须依靠一套有效的网络管理手段来监测和管理整个网络。SDH(同步数字体系)
的应用也离不开网络管理。SDH 网元管理系统管理 SDH 设备,南向接口在系统中
完成下发操作和数据采集工作。本文主要探讨的是 SDH 网元管理系统中南向接口的
设计与实现。
本文首先分析了当前网络管理软件的研究现状,简单介绍了基于 J2EE(Java2
企业版)架构的厂商级-子网层-多业务传输设备网管系统的设计与实现,它主要
针对各种 SDH 传输设备。由于各厂商生产的 SDH 网络设备通信接口及通信规程都
有差异。为了屏蔽各 SDH 设备之间的差异,系统利用南向接口管理真实网元,下发
相关操作命令,为每种设备提供一个适配器,为业务模块提供统一的接口。因此系
统的高层设计具有较高的移植性和通用性。本文的重点是如何设计与实现南向接口,
使之能够屏蔽底层设备差异,并且采用缓存、多线程并行处理面临的大量数据操作
以提高系统的性能。文章举例说明了 SDH 网管系统如何使用南向接口进行操作的详
细过程。最后论文总结了南向接口的优点与缺陷及将来的改进方向。

Abstract
Network’s stability, efficient and accurate operation is extremely important with the
rapid development work technology. So, we must depend on a suite of effective
network management methods to monitor and manage work. SDH (Synchronous
Digital Hierarchy) application also cannot be separated work management. SDH
network element management system needs to manage many SDH equipments.
Southbound interface of the pletes the operation and data collection work.
The paper discusses the design and implement of southbound interface of work
element management system.
This paper analyzes the work management software research and
development status, simply introduces the design and implement of management system
which bases on J2EE framework. Because the work equipments produced by
different manufacturers has munication interfaces and regulations. In order
to shield the difference between the SDH equipments, system uses southbound interface
to manage equipment, transfer mand, supply an adapter for which equipment,
and supply uniform interface for operation module. So the top design of the system can
be transplanted and reusable. The emphases of this paper is how to design and implement
southbound, which can shield the difference between the equipments and increase
