天地一体化网络协议研究

Research on Protocols of Space-ground Integrated Network

协议作为网络高效运行的关键,需要与具体网络环境、应用服务相适应。卫星通信网络与地面网络运行环境存在较大差异,天地一体化网络协议在设计时需要充分考虑到天基网络与地面网络的差异性,借鉴国内外空间信息网络协议体系的最新研究成果,结合我国天基网络特点,提出了适用于我国天地一体化网络的增强空间融合协议体系,在该协议体系下异构卫星网络的用户可直接通过天地一体化网络实现业务互通。

The protocols are crucial to high-efficiency operation of network,and they must adapt to operation environment of network and application service.In the design on space-ground integrated network protocols,it is required to fully consider the differences between satellite network and ground network.Based on achievements on space information network protocols at home and abroad and in view of the characteristics of space-based network at home,this paper proposes the Enhancement Space Convergence Protocols（ESCP） suitable to the space-ground integrated network at home.The users in heterogeneous satellite network can achieve the intercommunication based on space-ground integrated network.
