摘　　要：在视频流高性能传输任务中,视频流量的传输问题已成为一个研究的热点。为此,提出了一种基于PF_RING技术的模型。通过使用PF_RING+TNAPI技术,并结合内存路由表、多核、多队列多线程等相关技术确保视频流的高性能传输。同时为了保证不同网域间共享视频数据的安全传输,提出了一种面向视频控制信令双向物理通道、视频流单向物理通道的视频传输模型。实验结果表明:所提方法在有效吞吐量、CPU使用率和平均误码率方面均取得了10%以上的提升。因此,所提方法通过采用PF_RING+TNAPI技术,同时结合视频传输模型,确保了共享视频数据传输的安全性和高效性。The problem of video traffic transmission has become a research focus in the task of high-performance video stream transmission.In this paper,a model based on PF_RING is proposed to solve this problem.In this model,PF_RING+TNAPI technology,memory routing table,multi-core,multi-queue multi-threading and other related technologies are used to ensure the high-performance transmission of video stream.At the same time,in order to ensure the safe transmission of shared video data among different network domains,a video transmission model for video control signaling dual channel and video data single channel is proposed.The experimental results show that the performance of the proposed method has been increased by at least 10%in effective throughput,CPU utilization,and average bit error rate.Therefore,by fusing PF_RING+TNAPI technology and video transmission system model,the proposed method ensures the security and efficiency of shared video data transmission.
