基于OSU的OTN技术在滇中引水工程中的部署策略

Deployment Strategy of Optical Transport Network Technology Based on Optical Service Unit in Central Yunnan Water Diversion Project

通信传输网络作为智慧滇中引水工程各项业务开展的基础网,对于提升工程智慧化运行管理起到基础性支撑作用。针对常见通讯系统配置存在的诸多局限,提出基于光业务单元(OSU)的光传送网络(OTN)技术构建引调水工程的通信传输网络,以智慧滇中引水工程传输网络为研究对象构建了滇中引水通信传输系统。从三网融合、接口类型、站点、组网方式、业务承载、网络保护、对接方案、智慧管理8个方面全面系统地对基于OSU的OTN技术在滇中引水工程进行部署。该网络技术可有效解决采用传统技术的传输网络存在的承载小颗粒业务复杂、业务映射层级过多引发的时延较高等问题,为智慧滇中引水工程构建安全实用、智慧高效的通信传输网络提供了可行策略,也为引调水工程的智慧化传输网络建设提供了新的方法和思路。研究结果对构建高速、灵活、智能、安全、面向未来的智慧滇中引水工程传输网络实践工作具有指导意义,也可供其他引调水工程通信网络建设借鉴。

Communication transmission network,as the basic network of Smart Central Yunnan Water Diversion Project,plays a fundamental role in intelligent engineering project management.In view of the limitations of common communication system configuration,the OTN(Optical Transport Network)technology based on OSU(Optical Service Unit)is proposed to build the communication transmission network of Smart Central Yunnan Water Diversion Project as a case study.The OTN technology based on OSU is comprehensively and systematically deployed and studied from eight aspects:three network integration,interface type,site,networking mode,service bearing,network protection,docking scheme and intelligent management.The OSU-based OTN technology could effectively solve the complex services of carrying small particle and the high delay caused by excessive mapping levels in traditional transmission network.It also provides a feasible strategy for constructing a safe,practical,intelligent and efficient communication transmission network in the Smart Central Yunnan Water Diversion Project.The research findings are of guiding significance for the practical work of constructing a high-speed,flexible,intelligent,safe and future-oriented transmission network of the Smart Central Yunnan Water Diversion Project,and can also be used for reference for the construction of communication networks in other water diversion projects.
