摘　　要：城域智能光网络的自组织特性包括自主配置、业务自适应、自主恢复和策略控制等。自主配置是一种灵活的网络资源分配机制,包括自动发现和自动配置。业务自适应通过对业务特征进行监测并据此对网络资源进行动态更新和修正。自主恢复提供了灵活高效的网络生存性策略。在分析了城域智能光网络业务环境特点的基础上,分别从业务和网络角度分析了城域智能光网络自组织特性及其关键技术,提出了一种城域智能光网络的节点结构及其控制策略。The self organization characters in MION（ Metro Intelligent Optical Network） include self-configuration, self-adaptability, self-recovery and policy control. Self-configuration provides a flexible resource allocation method including automatic discovery and automatic configuration. Self-adaptability measures the quality and quantity of service and offer dynamic resource update and adjustment. Self-recovery provides an agile and robust survivability scheme. This paper focuses on the service self organization phenomenon in MION and presents some crucial enabling techniques based on both the service and the network viewpoint. A novel MION node architecture and its control scheme are provided.
