[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.
