摘　　要：时间同步网作为基础支撑网络,对于各种业务网的发展和质量保障起到十分重要的作用。针对不断建设和扩容的时间同步网的规划合理性和同步性能可靠性缺乏验证手段的问题,根据时间同步网典型架构,构建了端到端误差模型、定时链路模型和同步节点设备模型,设计并实现了时间同步网建模仿真软件,可实现对时间同步网设备和定时传递链路的建模、同步性能计算和误差分析以及网络质量综合评分。对示例网络进行仿真应用的结果表明,软件满足功能设计需求,可为时间同步网的规划建设、扩容优化等提供技术支撑。As a basic support network, time synchronization network plays a very important role in the development and quality assurance of various service networks. In view of the lack of means to verify the planning reasonableness and synchronization performance reliability of time synchronization network which is continuously constructed and expanded, according to the typical architecture of time synchronization network, the end-to-end error model, timing link model and synchronization node equipment model are constructed, and the time synchronization network modeling simulation software is designed and implemented, which can realize the modeling of time synchronization network equipments and timing transmission link, synchronization performance calculation and error analysis, as well as the comprehensive scoring of network quality. and comprehensive network quality scoring. The simulation results of the sample network show that the software meets the functional design requirements and can provide technical support for the planning and construction of time synchronization network, capacity expansion and optimization.
