摘　　要：航天器测试网络是航天器自动化测试运行、测试数据监测分析等测试业务运行的信息通道,它的性能将极大影响航天器试验测试效率与试验数据的应用效能。针对传统航天器测试网络存在的物理独立部署、人工迁移、存在数据孤岛以及无法高效交换共享的不足,本文参考借鉴软件定义网络技术,设计了基于虚拟局域网及软件定义网络技术的软件定义航天器测试网络。该测试网络技术具备良好的软件重构、区域隔离、测试信息汇聚共享性能,能够通过软件重构,自动化迁移部署航天器测试网络;通过网络区域逻辑隔离,确保各航天器测试指令运行区域受控、安全;通过全局测试数据汇聚实现多航天器测试数据的交换共享,从而有效解决了航天器测试网络快速部署、测试指令安全运行与测试数据交换共享的问题,有力推动了装备试验数据工程的建设工作。The integrated spacecraft test network is the information pipeline of the automatic operation of the test,the monitoring and analysis of test data,and other test business operations.Its performance and usability significantly influence the efficiency of the integrated spacecraft test as well as the application of the test data.In light of the shortcomings of the traditional integrated test network,such as manual migration,low deployment efficiency,isolated data islands,and an inability to exchange and share information efficiently,an integrated test network based on the Virtual Local Area Network and Software Defined Network technology is designed with reference to a Software Defined Network.The proposed network performs well in terms of area isolation,software reconstruction,and aggregating and sharing test information.The network can be automatically migrated and deployed by software reconfiguration.The safety of the test command operation area of each spacecraft is ensured by logically isolating the network area.The test data are exchanged and shared by global data aggregation.This technology realizes rapid network deployment,safe instruction operation,and test data sharing to advance the engineering of test data equipment.
