With the further development of human deep space exploration, the successful transmission of scientific data, remote sense, telemetry, and remote data, which are used during the deep space exploration, has become a keystone to complete the mission of deep space exploration. The traditional point-to-point communication mode of deep space communication can not meet the need of today’s deep space exploration, it right now has become inevitable and necessary that using the nodes, which have the ability to perform the function of remote communication, to weave a general InterPlaNetary backbone networks.InterPlaNetary backbone networks has been the hart of the InterPlaNetary Networks. The frequent shifting of the communication nodes of InterPlaNetary backbone networks will touch off the dynamic change of the main networks’topologic structure, which can generate great impact on the network performance of the transmission protocol. In addition, there are many aspects of the nodes of InterPlaNetary backbone networks including the long distance between two nodes, the high Bit Error Rate, the high asymmetry between the forward link rate and the backward link rate, and the frequent break of communication link which can lead to the sharp reduction of the performance of the traditional transmission protocol or even its functional failure.This paper has offered a new mode of InterPlaNetary backbone networks and a new transmission protocol which can be applied to the transport layer of the main network by professionally analyzing the stability of Lagrangian point and the transmission mechanism of the present transmission protocol which is adaptive the deep space environment. The major tasks of my research are presented here:My research has offered a mode of InterPlaNetary backbone networks environment which is based on the Lagrangian L4point and Lagrangian L5point,it can keep the maximum continuity of the communication between the Mars and the Earth.IPNBN-TP protocol which is adaptive to the InterPlaNetary backbone networks has been provided in my research. This protocol is built on the mechanism of windows and subdivided Round Trip Time,can seize the link resource in a controllable and quick manner,caculated the transmission rate and link packet error rate based on acknowledgements,which can provide the initial argument for rate-based twice active transmission mechanism.In addition, IPNBN-TP also adopt the rate-based twice active transmission mechanism to ensure the reliability of the transmission.By analyzing the lab data, my research takes STK to build the scene of InterPlaNetary backbone networks and channels its nodes into Matlab to realize the functions of InterPlaNetary backbone networks mode and IPNBN-TP protocol to pave the way of theory and data for our country’s plan of deep space exploration.
