摘要

摘要: 空间信息网络的发展呈现出节点异构和功能多样化趋势，网络节点间的时间同步是实现协同任务的重要技术基础。论文对空间信息网络的时间同步业务特性进行了分析，并提出基于多跳中继的时间同步误差模型。针对非实时时间同步业务特点，提出了钟差相对不变性概念，并基于此提出了面向时间同步业务的空间信息网络拓扑聚合图模型。不同于面向通信业务的网络拓扑模型，该模型的建立以节点时钟性能和时间比对链路性能为约束条件，反映了时间同步业务的特性和需求。针对该模型进行了空间信息网络时间同步仿真实验，实验结果表明基于该模型进行多跳中继时间同步，可以减少时间同步过程的路由筛选及建链次数，降低时间同步业务的链路资源消耗，同时可以达到更高的时间同步精度。

Abstract: The trend of heterogeneous node and functional diversification is presented in the development of space information network. The synchronization of network nodes is the technical foundation of task coordination of network nodes. The characteristic of time synchronization service of space information network is analyzed in this paper and the error model of multi-hop relay time synchronization is given. The concept of clock offset relative invariance is proposed based on the characteristic of non-real-time time synchronization, and a novel space information network topology aggregation model is given for time synchronization service. Differing from normal communication-service-oriented network models, the constraint condition of the model establishment is the performance of node clock and the time synchronization link, and the characteristic and requirement of time synchronization service is concerned. Simulation of space information network time synchronization is made according to the model. In the process of multi-hop relay time synchronization based on the model, less routing and linking number is needed. The link resource consumption is reduced, and the time synchronization precision is improved.
