本发明属于无线通信技术领域，具体涉及一种低时延QUIC协议传输方法及系统，本发明传输方法中采用一种主动的基于丢包率估计的前向纠错编码机制，将编码机制称为流编码；在传输过程中所有丢失分组都依赖流编码进行恢复；发送端通过对链路丢包率的估计自适应的调整流编码的目标码率并基于目标码率自动选择是否发送修复分组；在传输过程出现分组丢失时，接收端利用之后接收到的修复分组完成数据恢复；传输方法中采用Westwood+作为QUIC的拥塞控制算法，降低了长时延链路中的端到端有序递送时延，并提高了链路的吞吐量。 The invention belongs to the technical field of wireless communication, and particularly relates to a low-delay QUIC protocol transmission method and system, in the transmission method, an active forward error correction coding mechanism based on packet loss rate estimation is adopted, and the coding mechanism is called stream coding; all lost packets in the transmission process are recovered by depending on stream coding; the sending end adaptively adjusts a target code rate of stream coding through estimation of a link packet loss rate and automatically selects whether to send a repair packet or not based on the target code rate; when packet loss occurs in the transmission process, the receiving end completes data recovery by using the received recovery packet; in
