一、前言自动交换光网络(ASON)是光传输网的热点技术,移动技术的蓬勃发展对光传输网提出了更高的要求。当前的网络发展趋势是ASON技术必然率先在光传输网中的长途骨干层和城域核心层出现。通过ASON智能光网络技术将核心网和综合业务传送网结合在一起,提供全新端到端的业务服务和管理模式。
I. Introduction Automatic Switched Optical Network (ASON) is a hot technology in optical transport network. The vigorous development of mobile technology puts forward higher requirements on optical transport network. The current trend of network development is that ASON technology takes the lead in the long-distance backbone layer in the optical transport network and the metro core layer. Through the ASON intelligent optical network technology, the core network and integrated service transport network will be combined to provide a new end-to-end business service and management model.
