自动交换光网络

随着通信业务的发展和网络融合趋势的进一步显现,现有传送网络已越来越难以满足用户的需求和网络运营的需要,自动交换光网络是光传送网技术的一次革新,具有一定的智能特性,较好地适应了网络发展的需要,代表了现有光网络向下一代网络演进的方向。ASON技术是光传送网的重大突破,文章简单阐述了新一代光网络——ASON的核心技术,介绍了ASON的总体结构,分析了ASON的技术优势,并说明了构建一个智能光网络网络拓扑结构的步骤。

Automatic Switch Optical Network

With the development of telecommunication service and further appearance of network integration trends, the existing transmission network is increasingly difficult to meet the demand of users and the needs of network operation. Automatic Switch Optical Network （ASON）is a teehnieal innovation of optical transmission network, which has some eharaeteristies of intelligence. ASON is an important development of transmission network. This paper firstly introduees the core technique, architecture and technique advantages of the new generation network--ASON, and then shows how to eonstruet an intelligent optieal network.
