摘　　要：ASON(自动交换光网络)是光传输网的一个趋势,而UNI(用户网络接口)是实现光网智能的重要标志。现有光网络绝大部分是SDH(同步数字体系)网络,实现基于SDH的ASON具有很大的实际意义。文中基于OIF UNI1.0描述了基于SDH的ASON中的自动发现、SDH标签请求删除和业务参数设置等过程,提出了一种ASON控制平面的实现方案并建立了相应的模型,最后运用该模型搭建的仿真代理实现了ASON的UNI功能。Automatic switched optical network is the trend of optical transmission networks, and UNI is the key to implement the intelligence of optical networks. As most optical networks are based on SDH, it is significant to implement based SDH ASON. Following a description of the process of automatic discovery, SDH label request/deletion and traffic parameters setting in ASON, a realization scheme of ASON control plan is proposed and a correponding model is established. Finally, the UNI function in ASON is realized using an emulation proxy based on the proposal model.
