This paper concerns the study of reliable transport protocols employed in cislunar telecommunication environments from the two perspectives of transport layer and application layer.Based on OPNET software,CCSDS process-level modules are developed.Four kinds of reliable transport mechanism including TCP,SCPS-TP,CFDP and MDP are configured,and protocol emulation and performance analysis are conducted.Experimental results show that,with the long propagation delay,high error rate and a high degree of asymmetry in front/back to the channel rate of the links,SCPS-TP losts the advantage of TCP performance enhancement,MDP is in general,while the CFDP reliable transmission protocol model can well adapt to this environment.
