基于同步骨干卫星的天地一体化IP网络互联模式设计及真星试验

Design and Verification of the Space-ground Integrated IP Network Interconnection Model Based on GEO

为解决同步骨干卫星系统无法支持空间与地面两个异构网络在网络层上直接互联互通的问题,提出基于同步骨干卫星的天地一体化IP网络互联模式。首先,阐述该天地一体化网络系统的组成和功能;接着,设计IP与CCSDS相结合的一体化互联协议体系,并以一个典型应用实例,说明协议栈的具体处理流程;最后,设计并完成基于同步骨干卫星的天地一体化IP互联试验。

A space-ground integrated IP network interconnection model is proposed to solve the network layer interconnection problem between space and ground segment in the current geostationary satellite system. Firstly,the system composition and function of the space-ground integrated network are described.Then,the protocol system of space-ground integrated network based on IP over CCSDS is given and the particular process of the protocol stack is also explained by a typical application. Finally,a test of the IP network interconnection model based on an on-orbit geostationary satellite is designed and finished. The results show that the space-ground integrated IP interconnection system can support various TCP/IP network applications efficiently.
