摘要
针对传统的UDP协议数据传输效率高但可靠性差的特点,提出了一种基于分区确认的分包与重组方法,使用自适应拥塞控制机制,并提出乘性增加减性减少(multiplicative increase reduced decrease,MIRD)算法对超时间隔进行处理,实现了音频数据的实时可靠传输,满足了特定场合下大量数据的传输实时性强和可靠性高的要求,提高了带宽利用的公平性和稳定性,拓展了UDP协议的使用范围。实验验证了该方法的可行性,音频数据传输的可靠性得到了提高。
A section-partition-based method for packet partitioning and restructuring is proposed, aiming at meeting the rigorous requirement of transmitting a great abundance of data reliably and real-timely in some specific situation in that the traditional UDP protocol has high efficiency but poor reliability.The time linit can be reset by adaptive congestion control algorithm of MIRD (Multiplicative Increase Reduced Decrease) by which the data can be transmitted reliably and also the fairness and stability of the bandwidth utilization can be improved. The method is validated to improve the reliability of the audio data transmission by the experiment.
