摘　　要：针对单向传输系统在高速网络环境中的传输可靠性问题,研究传输可靠性的保障机制并设计一个高效可靠的单向传输系统。为了提高传输可靠性,利用Cauchy Reed-Solomon(CRS)编码设计编码、解码模块,通过尽可能地恢复传输过程中丢失的数据包提高传输可靠性;为了提高传输效率,利用PF_RING设计系统的数据转发模块,通过PF_RING高速捕获数据包能力提高CRS编码在高速环境下的编码、解码效率以及降低冗余数据对带宽的影响。实验证明在高速环境下,改进的单向传输系统确实可以大幅度降低丢包率,提高传输效率和运算效率,提高传输可靠性。Aiming at the transmission reliability problem of unidirectional transmission system in high-speed network environment,the guarantee mechanism of transmission reliability is studied and an efficient and reliable one-way transmission system is designed. In order to improve the transmission reliability,the coding and decoding modules are designed by Cauchy Reed-Solomon(CRS)coding,and the transmission reliability is improved by recovering the lost data packets as much as possible during transmission;in order to improve the transmission efficiency,the data forwarding of the system is designed by using PF_RING. The module,through PF_RING high-speed data capture capability,improves the encoding and decoding efficiency of CRS encoding in high-speed environments and reduces the impact of redundant data on bandwidth. Experiments show that in a high-speed environment,the improved one-way transmission system can significantly reduce the packet loss rate,improve transmission efficiency and computational efficiency,and improve transmission reliability.
