摘　　要：针对传统光传送网络(OTN)设备业务单盘数量过少,且槽位扩容会造成业务中断,成本过高的问题,文章提出了基于集群架构的光传送网(COTN)通信系统。COTN设备管理系统的设计是实现现网设备从OTN升级到COTN的可靠技术保障,是保障COTN中业务承载单盘的兼容性与扩展性的有效技术手段,文章采用单网元多子框的形式对COTN设备管理系统进行设计。对COTN与传统OTN设备在数据收集、框间保护和业务处理等方面进行了对比研究,研究结果表明,COTN设备业务槽位的扩展满足承载业务扩容的低成本与动态可持续化的需求。Aiming at the problem that the number of single disks of traditional Optical Transport Network(OTN)equipment business is too small,and the expansion of the slot will cause business interruption and high cost,this paper proposes a Cluster Architecture of Optical Transport Network(COTN)communication equipment.The design of the COTN equipment management system is an effective technical guarantee to upgrade existing network equipment from OTN to COTN,which is the only technical means to ensure the compatibility and scalability of the single-disk service bearer in COTN.Therefore,this paper adopts a single network element and multiple sub-frames.A comparative study of COTN equipment and traditional OTN equipment in the areas of data collection,inter-frame protection,and service processing show that the expansion of COTN equipment service slots meets the low-cost and dynamic sustainability requirements of bearer service expansion.
