基于CORBA的传送网EML-NML接口研究与实现

文章系统地介绍了电信管理网（TMN）管理体系结构和各功能层接口参考点的关系。分析了现有网元管理层-网络管理层（EML-NML）接口Q3标准在面向对象的分布式环境下的不足以及通用对象请求代理体系结构（CORBA）在分布式应用环境下的优势。详尽地阐述了CORBA技术在EML-NML接口中的应用，以及传送网管理平台上基于CORBA的EML北向接口实现体系结构，并提出了一种基于CORBA技术的通用EML-NML接口设计实现方案，最后给出了以ORBIX6．1为CORBA实现平台的TMN总体运行方案。

Study and implementation of CORBA technology in EML-NML interface

This paper presented a systematic introduction to the relationship between the TMN architecture and the interface reference points of all layers of function, analyzed the short coming of the Q3 standard for EML-NML interface under the object-oriented distributed environment, and the superiority of CORBA over distributed application environment, The paper also elaborated on the application of CORBA technology in EML-NML interface, and a CORBA-based architecture for realization of EML norward interface under the transport network management platform, put forword a CORBA-based realization scheme for common EML-NML interface design. Lastly, the paper gave an overall operation scheme of TMN using ORBIX 6.1 as the realization platform.
