Abstract: The present invention relates to the technical field of satellite communication, and disclosed is a DPDK-based satellite channel high-speed reliable data transmission method. By using a polling receiving mode provided by a DPDK in a user space, data is directly received from a network card to an application program and bypasses a Linux kernel network protocol stack, thereby avoiding frequent CPU interruption and memory copy and thus significantly improving the data processing efficiency. A received data packet is processed in the user space according to a protocol type of the received data packet. A non-TCP packet is simply cached and then forwarded out via another port after a token is obtained by waiting; a TCP packet needs to be processed according to a SCPS-TP protocol flow so as to overcome the characteristics of a satellite channel such as long time delay and high error code. The present invention can effectively improve the satellite channel utilization rate of reliable data transmission, is completely compatible with a TCP protocol, and is especially suitable for reliable data transmission in a high-throughput satellite system.
