摘要

The establishment of satellite Internet is a crucial step in the future development of the satellite communications industry. Therefore, in the current inter-satellite link environment where laser links and microwave links coexist, a new switching system architecture is needed. This paper summarizes the business capabilities that satellite Internet must meet based on the current development status of satellite communications, as well as the characteristics and transmission requirements of satellite Internet services. It also investigates and analyzes the current state of switching technology, summarizing the applicability of existing switching technologies in the construction of satellite Internet. Based on the analysis results, an end to end network on the satellite is constructed, leading to the design of a satellite optical-electrical hybrid architecture.
