本文介绍了对多波长光传送网实施基于ＴＭＮ 管理中涉及的信息建模的方法问题，在建议了一组用于描述光传送网通用功能的基本传送对象类的基础上，讨论了几种典型ＯＸＣ′ｓ 信息建模的方法，包括可能用到的对象类，这些方法和对象类为建立实际的、完整的ＯＸＣ′ｓ 信息模型提供了的基础－
This paper introduces the method of multi-wavelength optical transport network based on TMN management information involved in the modeling method proposed in the light of a group of basic transport objects used to describe the general function of optical transport network based on the discussion of several typical OXC’s approach to information modeling, including possible object classes, provides the foundation for building a realistic, complete OXC’s information model -
