Abstract
Recently,with the rapid development of space network,the Consultative Committee for Space Da-ta Systems( CCSDS) protocol structure has become the standard. The mid-low speed data relay terminal e-quipment of Tracking and Data Relay Satellite System( TDRSS) ground station has been modified. After in-serting routing gateway card and loading CCSDS protocol software,the previous mid-low speed data relay terminal equipment has become the one with routing gateway function. Then the space-ground network demonstration system has been constructed with two mid-low speed data relay terminal equipment with gateway function and channel simulator. The performance of HTTP application based on the TCP protocol and PEP enhanced protocol is analyzed and compared,which proves that PEP enhanced protocol suits the transportation of space-ground network system better.关键词
