光网络的发展与展望

首先简要介绍了光网络的基本概念,然后阐述了光传送网的主要优势,接下来分别论述了IP业务量对传送网结构的影响、从点到点WDM向光联网演进的必要性和演进的步骤以及全光光交叉连接设备的现状与发展,最后阐述了光传送网络向ASON演进的必然趋势.

Development and Expectation of Optical Network

After introducing the basic conception of optical network and the major advantages of optical transport network, this article discusses the influences of IP traffic to the structure of transport network, the necessiW and processes for the evolution from point-to- point WDM to optical networking, and the sLltus quo and development of all optical crossconnector respectively. Lastly, it presents the inevitability, for the evolution from optical transport network to ASON.
