With the development of Internet technology,how to use TCP protocol which is based on reliable connection as transfer mechanism in space environment becomes a new communications problem.Based on full study on the characteristics of space science data services and researching on the features of space transmission channel,this paper analyses the defects of TCP in space environment such as long time-delay and high error rate etc.To solve these problems,two high speed transmission solutions based on TCP protocol are put forward.The principle and the implementation of these two solutions are explained in detail.Finally,these solutions are proved to be feasible by system simulation,and can significantly improve the transmission performance.
