Abstract


To meet the development needs of the future of space exploration , a few of the topics recommended by the Advisory Committee on Space Data Systems CCSDS space data link protocol analysis and research . The paper first describes the history of the development of CCSDS space data link protocol , China, its research and the need for the eventual adoption of CCSDS recommendations . Reference to the recommendations of the CCSDS space data link protocol and combined with the actual needs of this project , summed up an effective transmission frame algorithm and determine the relevant parameters , using OPNET simulation tool Telemetry TM remote TC protocol modeling . Using this model , the type of multi-service data source packet distribution and COP-1 , the closed-loop control mechanism simulation . Generic protocol performance analysis method , TM and TC protocol model has been established to carry out the simulation performance . First, the use of the TM model , respectively, from the source packet and frame data field length change angle simulation protocol communication link throughput . Then the introduction of the concept of effective throughput , from the perspective of theoretical simulation obtained remote packet data field length of segment data domain and frame effective throughput . Finally, TC protocol example of practical application , authentication mechanisms may impact the agreement . Topic modeling and simulation to find interference agreement , at the same time as an important innovation , the papers presented at the last two interference method based on the effective throughput performance and authentication mechanisms .
