摘　　要：通信网络中的多路径传输因其高可靠性,聚合带宽,容错和负载平衡等特性而受到广泛关注。多路径传输技术的原理为通信终端在传输数据时,可同时使用终端的多个网络接口,为满足用户对高质量实时流媒体业务需求提供了可能性。本文首先分析多路径TCP进行流媒体传输时的技术原理及不足,为了解决多路径TCP存在的问题,提出了多路径UDP技术,并对其框架及关键技术进行分析和介绍。最后对多接口环境下进行实时流程媒体传输做了总结并提出了进一步研究方向。Multi-path transmission in communication networks has received widespread attention due to its high reliability,aggregate bandwidth,fault tolerance and load balancing.The principle of multi-path transmission technology is that the communication terminal can use multiple network interfaces of the terminal at the same time when transmitting data,which provides the possibility to meet the needs of users for high-quality real-time streaming media services.This article first analyzes the technical principles and shortcomings of multi-path TCP for streaming media transmission.In order to solve the problems of multi-path TCP,multi-path UDP technology is proposed,and its framework and key technologies are analyzed and introduced.Finally,the real-time process media transmission in a multi-interface environment is summarized and further research directions are proposed.
