| 摘要: |
| 近年来，构建全球覆盖、满足陆、海、空、天各类用户接入通信需求的卫星通信网络成为研究热点。卫星通信网络涉及网络构型、链路传输、接入控制、路由交换、管理控制以及安全保密等多层面、多类型技术体制，网络的技术体制、指标体系不容易确定，需要研究相应的体制验证方法，对网络架构、各层面技术体制、功能性能指标等进行有效验证，通过迭代优化设计最终确定网络技术体制，以便为我国卫星通信网络的研制建设提供技术支撑。首先给出了几种典型的试验验证方法，并分析比较了其优缺点，在此基础上给出了卫星通信网络的体制验证方法及验证内容实例，可为后续研究工作开展提供参考。 |

| Abstract: |
| In recent years,it has become a hot topic to build a space-based transmission network,which has the characteristics of global coverage,broadband high-speed and meets the communication requirements of various users in land,sea,air and space.Space-based transmission network involves multiple technologies,such as network architecture,link transmission,access control,routing and switching,management control and security.The system and performance of the space-based transmission network are hard to be determined.As a result,it is necessary to build the corresponding evaluation and verification environment to verify the network architecture,technology system and performance of the space-based transmission network,which can provide iterative optimization design and determine the system of the space-based transmission network,so as to provide certain reference for the construction of space-based transmission network.In this paper,typical verification methods are presented at first.The merits and demerits are analyzed.Then,a specific example is given to demonstrate the verification methods and contents of the space-based transmission network,which can provide certain reference for the future work. |
