| Summary: | In the space environment where laser links and microwave links coexist, the development of satellite Internet optical/electric hybrid switching will help promoting the construction of air-space-ground integration.According to the characteristics and transmission requirements of satellite Internet services, the current status of electrical domain switching technology and optical domain switching technology were investigated and analyzed, and the applicability of existing switching technologies in the construction of satellite Internet was summarized.At the same time, according to the analysis results, the end-to-end network on the satellite was constructed, and based on this, the design of the optical/electric hybrid switching architecture on the satellite was completed.It mainly included the interface, electrical domain adaptation module, optical domain adaptation module, optical/electric convergence module, optical switching module, packet switching module and management control module. |
