The spacecraft integrated test network is the information pipeline of the automatic test operation, test data monitoring and analysis and other test business operation, whose performance and usability greatly affect the efficiency of spacecraft integrated test and test data application. In view of the shortcomings of traditional integrated test network, such as manual migration, low deployment efficiency, isolated data island, and inability to exchange and share efficiently, an integrated test network based on VLAN (Virtual Local Area Network) and SDN (Software Defined Network) technology is designed with reference to SDN, which has good performance of area isolation, software reconstruction, test information aggregation and sharing. The network can be automatically migrated and deployed by software reconfiguration. The safety of each spacecraft test command operation area is ensured by network area logical isolation. The test data are exchanged and shared by the global data aggregation. The technology realizes the rapid network deployment, instruction safe operation and test data sharing, which promotes the equipment test data engineering.
