摘　　要：针对当前光传输/接入网的传输设备,提出了一种基于Hub-spoken结构的点对多点网络管理方案。利用数字包封开销技术中的开销GCC0作为承载监控管理信息的通道,使得低损耗、小型化的局端设备能够监控管理至多8台远端节点设备。针对如何有效地传输监控管理多台远端节点设备的信息,自定义了In-band协议和简单命令协议,并基于STM32开发了远端节点设备,详细介绍了软件开发架构与In-band实现流程。实验结果证明,局端设备能够同时监控管理多台远端节点设备。Based on the transmission equipment of the current optical transmission/access network, a Point-to-Multipoint （P2MP） network management scheme based on Hub-spoken structure is proposed. Digital wrapper overhead GCC0 is used as carrier monitoring and managing information channel, which can achieve low-loss, miniaturized terminal device monitoring and managing up to 8 remote node devices. In-band protocol and simple command protocol are also proposed in this paper to effec- tively transmit information of multiple remote node devices for monitoring and management. The remote node device is devel- oped based on STM32. The software development framework and in-band implementation flow are introduced in detail. The experimental results show that the central office equipment can monitor and manage the multiple remote devices at the same time.
