In ground operation and control subnet and payload information network using IPsec, GRE or RFC2003 three IP tunnel protocol, through the platform information network and the telemetry, tracking, and command network, the user data encapsulated into IP tunnel protocol can be routed in communication link between the spacecraft and the ground so as to support the payload and the ground transport flexible end-to-end communication between two control terminals. The information management architecture of world integration was designed to support IP communication, the setting of router and IP address allocation were given，and the communication efficiency and timeliness of three IP tunnel protocols were calculated and analyzed. The analysis result shows that the IP tunnel protocol is of revolutionary significance to change the traditional ground operation and control mode and improve the efficiency of operation and control.
