High efficient interactive transmission method applicable to deep space interplanetary satellite network

The invention belongs to the technical field of deep space interplanetary satellite network transmission. The deep space interplanetary satellite network transmission is characterized by comprising the following steps of: beginning to send information data in a connection establishing stage; adopting a sending strategy of sending three priorities of packet data at equal intervals in a crossed way; adopting an initialization sending strategy; judging data loss reason according to loss situations of different priorities of packet data; analyzing network congestion degree; adopting a corresponding information traffic control algorithm; and adopting an actively and periodically selected receiving and answering strategy. In a deep space interplanetary satellite network with extremely high random error codes, serious burst error codes, extremely long propagation delay and very asymmetric channel width, by using the method, the connection waiting time consumption can be avoided, the information traffic can be rapidly increased, the link error code and congestion situation can be effectively distinguished, and the corresponding information traffic control can be adopted according to the congestion degree of the network to largely reduce the transmission bandwidth requirement of a reverse link.
