| 摘 要： | 在数据传输网络中,与其它协议相比,UDP协议在速度上有一定的优势,但也存在着传输可靠性差的问题.提出一种补发机制,在此基础上,结合数据包的重发机制、流量控制和拥塞控制机制,给出一种增强型可靠UDP传输协议ERUDP(Enhanced Reliable UDP).文章分析了ERUDP的基本原理,阐述它的实现方式并使得该协议在高清媒体播放终端系统中获得了实际应用.实测结果表明,本文提出的传输方式在速度上优于TCP以及传统的RUDP(Reliable UDP,可靠UDP),同时又保证了可靠性.

| Abstract: | There are certain advantages in terms of speed for UDP protocol as compared with other agreements in the data transmission network,however,the transmission reliability is poor. This paper presents a supplement mechanism,and on this basis,presents a enhanced reliable UDP transport protocol combined with retransmission mechanism,flow control and congestion control mechanisms,ERUDP(Enhanced Reliable UDP). The paper analyzes the fundamentals of ERUDP,and expatiates its way of implementation. Finally,the paper i... |
