中文摘要：

对智能光网络的概念和主要特点作了考察。当波分复用技术不断成熟时，在一个WDM通道容量和一个典型的对带宽的连接请求之间就存在着一个巨大的鸿沟，如果一个波长的整个带宽被分配给一个低速的连接，这个传输容量的大部分将会被浪费。智能光网络是一种独立于业务的电信网络，也就是说，智能是在分布于整个网络之中的计算机的节点里的。这给网络操作者提供了更加有效的发展和控制业务的手段。新的容纳能力能被迅速地引进到网络中去。一旦引入了，业务就很容易适应与满足客户的需求。分析了各个领头的标准组和组织的工作，指出智能化是光网络发展的趋势，并将是光网络的未来。

英文摘要：

The concept and main characteristics of the intelligent continues to mature, there exists a large gap between the capacity a typical connection request. If the entire bandwidth of a large portion of the transmission capacity could be wasted. optical network are investigated. As WDM technology of a WDM channel and the bandwidth requirement of wavelength channel is allocated to a low-speed connection, a An intelligent network is a service-independent telecommunications network. That is, intelligence is placed in computer nodes that are distributed throughout the network. This provides the network operator with the means to develop and control services more efficiently. New capabilities can be rapidly introduced into the network. Once they are introduced, services are easily customized to meet individual needs. Progress made by leading standardization groups and organizations for developing optical networks in are analyzed. It is concluded that the intelligentization will be one of the development trends of optical networks and therefore represents the future of optical networks.
