摘　　要：通过对智能光网络的网络结构和相关技术的分析,提出了一种对传统光网络设备进行智能化改造的新技术。该技术通过构建一个运行于EMS和传统光网络传输设备之间的“机顶盒”设备,来实现控制平面的基本功能。“机顶盒”依据EMS指定的相关参数,计算满足业务要求的子网内端到端的显式路径;并且通过RSVP-TE信令建立LSP连接,为业务建立承载通路。该技术融合了网络管理、信令、路由等协议,能够实现光网络设备的平滑升级,降低风险,节省资金投入。By analyzing the network architecture and the related technology of automatically switched optical network （ASON）, a new technology of reconstructing the traditional optical network into ASON is proposed. In this technology, every optical network element （NE） is equipped with a top-set-box which locates between EMS and NE to implement the function of the control plane. The top-setbox receives the management information from EMS by SNMP Agent and calculates the service＇s end-to-end path by OSPF sub-module and establishes a LSP link by OSPF-TE sub-module. This technology combines the protocols including the network management, signaling, routing, and is able to reduce the evolution risk and the investment cost.
