Design and verification of a satellite-terrestrial integrated IP network model for the Global Energy Interconnection

In order to meet the pressing demand for wide-area communication required by the Global Energy Interconnection (GEI), accelerating the construction of satellite-terrestrial integrated networks that can achieve network extension and seamless global coverage has become the focus of power communication technology development. In this study, we propose a satellite-terrestrial integrated network model that can support interconnection and interoperation on the IP layer between the satellite system and the terrestrial segment of the existing power communication system. First, the composition and function of the satellite-terrestrial collaborative network are explained. Then, the IP-based protocol stack is described, and a typical application experiment is conducted to illustrate the particular process of this protocol stack. Finally, a use case of IP interconnection that depends on GEO satellite communication is detailed. The experimental study has showed that the satellite-terrestrial collaborative network can efficiently support various IP applications for the GEI.
