摘　　要：教育信息化已经步入了智慧校园这一新阶段,具有新的内涵和技术需求.为了探索满足智慧校园体系架构中网络层功能需求的技术路线,在分析智慧校园的特征、典型应用和现有关键技术的基础上,针对目前基于树状PON结构的一些限制,包括支持虚拟专用网络及提供全分布式故障检测和恢复能力,提出了一种基于简单自愈环的时分复用无源光网结构,并研究了该结构的自动保护倒换(APS)装置的具体实现方案.Educational informatization has entered a new stage of smart campus,which has new connotations and technical needs.In order to explore the technical route to meet the functional requirements of the network layer in the smart campus architecture,based on the analysis of the characteristics,typical applications and existing key technologies,some limitations of the current tree-based PON architecture are analyzed,including supporting virtual private network and providing fully distributed fault detection and recovery capabilities.A time division multiplexing(TDM)passive optical network(PON)structure based on simple self-healing ring is proposed.Then,the realization scheme of the automatic protection switching(APS)device with this structure is studied.
