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.
