Research on TCP Control Optimization in Satellite Communication Network

Satellite communication is the main means of shore ship communication, which uses TCP/IP protocol to realize remote transmission of services such as TT&C data, synchronous system data, telephone and graphics access to shore station. Affected by factors such as the bandwidth and link instability of shore vessels, the shore ship satellite communication link based on TCP transmission application has problems such as low data transmission rate and low communication service transmission efficiency. In this paper, the characteristics of shore ship satellite communication information transmission, TCP transmission segmentation spoofing, rate control, error control and other characteristics are studied, and the gateway protocol is added to optimize the data transmission characteristics of shore ship satellite communication, so as to effectively improve the data transmission efficiency of shore ship communication.
