Abstract


Advisory Committee of Space Data Systems (CCSDS, Consultative Committee for Space Data System) is committed to the development and aerospace monitoring various communication protocols and data transmission specifications ; adapt space communication environment , CCSDS launch an improved version of the TCP / IP SCPS (Space Communication Protocol Specification), intent to achieve interconnection of TT \u0026 C network with the Internet ; This article around SCPS protocol stack carried out the following work : First, in view of the lack of relevant Chinese literature more detailed study of the SCPS protocol stack . Summarized a lot of information in English on the basis of the SCPS- FP the SCPS protocol stack in the SCPS -TP protocol mechanisms of SCPS -SP SCPS-NP made ??a detailed analysis of the performance of SCPS-FP and SCPS-SP protocol the preliminary evaluation , discussed the prospects for the development and application of the agreement and SCPS-FP and SCPS-SP . Second, the study of the improvement and expansion of the SCPS-TP protocol made ??in response to space communications environment , including how to deal with the problem of data loss , bandwidth is limited and asymmetric link . The scalability of SCPS-TP -depth study. SCPS-TP protocol based on RTT prediction improvement program . SCPS-TP protocol in Application Vegas congestion control algorithm , based on the changes in the RTT to change the size of the congestion window ; changing space network topology , Vegas can not determine RTT change is due to congestion or due to changes in network topology . The program applied to BP neural network protocol , the RTT learning neural network predictive capability to determine reasons for the changes , to improve the adaptability of SCPS-TP . The simulation results show that the scheme can improve the throughput of SCPS-TP protocol . In this paper, SCPS-TP protocol classification based on network conditions improvement program. Embedded BP neural network , SCPS-TP can classify the state of the network traffic , consider the three cases of normal , congestion , and topology changes accordingly decided to change direction of the congestion window . The simulation results show that better enhance the effect of the program on the protocol performance . Finally , describe the transplantation process , the BP neural network embedded NS2 simulation platform also introduces simulation data handling mechanism .
