Abstract

With the rapid development of aerospace

aviation and ground communication technologies

it has become an inevitable trend for the development of communication networks to build an integrated space-terrestrial integrated network with global seamless coverage

on-demand access and on-demand services.The realization of the space-terrestrial integrated network based on the standard space optical transport network protocol was studied. Firstly

it is clear that the space optical transport network is the fundamental cornerstone of building the integrated network

the status quo of the standards of space optical communication was described

and the dilemma of the limited satellite information exchange caused by the differences in systems was analyzed. Furthermore

the networking function of the space optical communication network was deeply explored at the protocol level. In view of the characteristics of high-speed satellite movement

frequent inter satellite link switching

and limited on-board resources

a new frame structure and reliable transmission protocol adapted to the space optical transport network were proposed to support the interconnection and communication of multiple constellations

and improve the efficiency of network resource utilization while ensuring accurate and reliable data transmission. Finally

the broad prospects of this network architecture for industrial applications were summarized

future research should focus on the layout of unified space optical transport network standardization

so as to lay a solid foundation for the efficient operation and wide application of the space-terrestrial integrated network.
