摘　　要：通过对锡盟PTN承载网络结构、光缆资源、业务配置及保护来发现网络短板,提出网络优化思路。锡盟移动PTN网络承载LTE、2G、3G、专线等全业务场景,业务稳定、可靠运行急需提升,针对网络安全保护进行专项提升,从而达到提高锡盟网络质量的目的,进一步提升用户满意度和网络日常维护效率。锡盟移动通过部署环网保护,对PTN网络异环多处链路中断、单节点失效故障对业务能够100%保护。同时对保护需求场景、模拟中断测试进行总结,总结出一套网络保护方法,指导网络规划与建设。Through carrying on the PTN network structure, Ximeng cable resources, business configuration and protection net- work to find short board, put forward the network optimization. Ximeng mobile PTN network carrying LTE ,2G, 3G. the whole line of business scenarios, business stability, reliable operation of the urgent need to enhance network security protection for special promotion, so as to improve the Ximeng network to further enhance the quality, user satisfaction and network mainten- ance efficiency. Through the deployment of mobile Ximeng ring network protection, PTN interrupt network ring multiple link, single node failure of business can be 100% protection. At the same time to protect the demand scenarios, simulated interrupt test were summarized, summed up a set of network protection method, guidance network planning and construction.
