As　the　development　of　integrated　space-terrestrial　information　network　technology,　the　satellite　network　technology　and　the　ground　network　technology　cannot　match　each　other　very　well,　even　though　they　are　all　mature　technologies.　In　recent　years,　with　the　integration　and　fusion　of　satellite　network　and　ground　interconnection　network,　through　the　transformation　and　modification　their　shortcomings　and　exerting　their　merits,　the　integrated　space-terrestrial　information　network　has　achieved　very　progress　and　its　implementation　technology　is　mainly　in　satellite　protocol　conversion　technology.　As　known,　there　is　a　big　difference　lying　in　the　design　requirement　of　space　network　protocol　and　ground　network　protocol.　For　example,　both　sides　of　the　dataflow　in　the　ground　network　provide　consistent　service,　meaning　that　the　protocol　should　be　symmetric;　However,　the　two　sides　of　the　dataflow　in　the　space　network　provide　different　procedures,　meaning　that　the　protocol　in　the　design　should　be　asymmetric.　The　main　reason　is　that　the　space　network　protocol　is　a　spatial　carrier,　the　other　side　is　the　ground　station,　and　they　have　different　procedures.　This　paper　devised　an　integrated　communication　network　framework　between　backbone　satellite　node　and　ground　station,　proposed　a　communication　architecture　of　space　ground　integrated　information　network　which　adopt　simplified　IP　protocol,　and　analyzed　the　feasibility　of　the　implementation　is　analyzed　from　the　view　of　business　process.　©　2016　IEEE.
