针对多路径并行传输中接收端数据流乱序和实时性差等问题，提出船舶远距离通信网络数据流低延时传输方法。首先，设计二次自适应滤波对消模型，消除跟踪干扰对船舶远距离通信网络数据流传输的影响；然后，结合远距离通信网络和多路径并行传输协议，预估接收端和发送端缓存容量。最后，基于接收端和发送端缓存容量，规划数据流传输中数据包的分配和传输策略。实验结果表明，该方法在数据流传输中链路抖动频率、拥塞频率和传输延时较低，数据流传输带宽较高。
In order to solve the problems of data stream disorder and poor real-time performance in multi-path parallel transmission, a low delay transmission method for data stream in ship long-distance communication network is proposed. First, a quadratic adaptive filtering cancellation model is designed to eliminate the influence of tracking interference on the data flow transmission of ship long-distance communication network. Then, combined with the long-distance communication network and multi-path parallel transmission protocol, the buffer capacity of the receiver and the sender is estimated. Finally, based on the buffer capacity of the receiver and the sender, we plan the packet allocation and transmission strategy in the data stream transmission. The experimental results show that the link jitter frequency, congestion frequency and transmission delay are low, and the transmission bandwidth is high.
