Abstract: The CCSDS protocol and DTN protocol in the field of space communications are studied.The analysis of CFDP protocol in the CCSDS protocol stack, the LTP protocol, and BP protocol in DTN protocol stack are done.The deep space communication protocol based on percolation is put forward. Then the hardware design of Mars probe traffic simulator, simulator Mars relay satellite communications ground station communication simulator and ground control center communications simulator are done and the deep space communications demonstration system consist of a Mars probe, 3 Mars relay satellite, 2 ground station and a ground control center is built up.

Key Words: CFDP; BP; The Demonstration System of deep space
