摘要
视频流应用场景虽然广泛,但存在传输质量低、视频质量较差的问题。为此,利用软件定义网络(SDN)对网络的可编程特性结合快速UDP Internet连接(QUIC),设计了一种针对视频流的基于SDN的分段路由多路径QUIC传输框架(SDNMQS)。该框架可根据网络条件动态分配路由,实现高质量传输服务。在仿真平台的模拟试验结果表明,SDNMQS在各项性能测试上优于其他传统方法,能提升视频传输质量,可为优化视频传输提供参考与借鉴。
Video streaming application scenarios are widespread and common,but there are problems with low transmission quality and poor video quality.To this end,a segmented routing multi-path QUIC transmission framework(SDNMQS)for video streams was designed using the programmable characteristics of software defined network(SDN)and fast UDP Internet connection(QUIC).This framework can dynamically allocate routes based on network conditions,achieving high-quality transmission services.The simulation test results on the simulation plat-form show that SDNMQS outperforms other traditional methods in various performance tests and can improve the quality of video transmission,providing reference for optimizing video transmission..
