摘　　要：【目的】随着互联网时代的到来,交通行业对数据通信的要求不断提高,加上车联网技术的发展带来大量数据,交通大数据的高速传输需求与有限的网络传输性能之间的矛盾日益增加。【方法】针对这一问题,本文在分析国内外车联网通信以及传输协议研究现状的基础上,结合车联网文件传输方面的应用需求,研究提出了一套基于QUIC(Quick UDP Internet Connection)协议的文件多流并行传输机制,对大数据文件进行压缩、分块、并行传输以及聚合。【结果】本文设计实现了一套面向交通大数据的高速文件传输系统,全面提升了数据传输的性能。【结论】实际的大数据文件传输实验结果表明,本系统在复杂网络环境下,传输效率显著优于传统的文件传输系统。[Objective]With the advent of the Internet era,the demand for data communication in the tran-sportation industry is constantly growing.Meanwhile since the development of Internet of Vehicles technology brings a large amount of data,the contradiction between the high-speed transmission demand of traffic big data and the limited network transmission performance is increasing.[Methods]To solve this problem,based on the analysis of the research status of communication and transmission protocols of the Internet of Vehicles in China and abroad,combined with the application requirements of file transmission of the Internet of Vehicles,this paper proposes a set of QUIC protocol-based multi-stream parallel transmission mechanism to compress,block-partition,parallel transmission and aggregation of big data files.[Results]This paper designs and implements a set of high-speed file transfer systems for traffic big data,which comprehensively improves the performance of data transmission.[Conclusions]The experimental results of the actual big data file transfer show that the transmission efficiency of this system is significantly better than the traditional file transfer system under the complex network environment.
