天地信息网络协议融合技术综述

天地信息网络融合可以实现空间与地面网络资源的充分共享和高效利用，国内外已提出多种天地一体化信息网络架构并从不同角度进行理论研究和关键技术攻关。面向CCSDS数据系统体制与空间通信协议规范（SCPS），在分析CCSDS协议体系结构及其应用发展基础上，讨论卫星链路应用TCP/IP的问题与关键机制，并综述星地一体化协议IPoC（IP over CCSDS）的技术研发与仿真研究进展。通过分析空间CCSDS协议体系与地面IP网络机制，为天地信息网络融合系统设计与网络协议研究提供参考。

Overview of space-ground information network integration techniques

Space-ground information network integration could efficiently share and utilize the space and terrestrial network resources. There are several space-ground integration information network architectures from different fields to investigate the theory and technique therein. CCSDS has developed advance mature systems and space communication protocol standards. Based on analyzing the CCSDS protocol architectures and application developments at home and abroad, we survey the problems and key principles of TCP/IP application in satellite links. Then, we survey the simulation, research and design progress of satellite-ground integration protocol IPoC (IP over CCSDS). Through the literature analysis of CCSDS protocols and IPoC protocols, this treatise is dedicated to support both system and protocol designs of space-ground information network integration.
