摘要
本文首先介绍光传送网的功能分层结构，然后讲述设备规范方法的演变和原子功能模型。
The paper introduces the layering functional architecture of optical transport network first. Then the evolution ofequipment specification approaches and atomic functional model are presented. Finally, characteristics of optical transport network hierarchy equipment functional blocks described employing atomic functional model are also presented briefly.
