光联网技术标准化体系及其现状

Standardization System of Optical Networking Technology and Its Current Status

自1998年开始,ITU和其他标准化组织就开始了对光传送网标准化的研究;2000年,自动交换传送网络的提出又使光传送网标准化改向另一个方向发展。为了使人们对光联网的标准有个系统的了解,文章介绍了ITU的光联网技术相关标准,以及其他标准化组织在自动交换传送网络标准化方面的研究进展。

In 1998, the ITU and other standardization organizations initiated research programs in OTN's standardization; in 2000, the appear of ASON made the research on OTN's standardization turn to another direction. Along with the introduction to ITU's optical networking standards, research advances on ASTN by other standardization organizations are also presented in order to provide a general view of optical networking standards.
