摘要

多路径传输协议的最新发展允许视频流在多个接口上传输，从而提高了会话可靠性和带宽性能。多路径传输的一个重要方面是在逐包的基础上选择路径。特别是，路径切换可能会导致线头阻塞效果，从而影响视频渲染。在这项工作中，我们分析了路径切换对多路径视频流的影响，并提出了旨在减少路径切换的新路径调度程序。我们利用网络性能度量和视频质量度量来描述新的调度器的性能改进以及各种网络场景下视频流的网络和应用层之间的交互。

Path Switching Schedulers for MPTCP Streaming Video

Recent developments on multipath transport protocols have allowed video streaming transmissions over multiple interfaces, improving session reliability as well as bandwidth performance. One important aspect of multipath transport is the selection of paths on a packet by packet basis. In particular, path switching may cause head of line blocking effects that may impact video rendering. In this work, we analyze the impact of path switching on multipath video streaming, and propose new path schedulers aimed at reducing path switching. We utilize network performance measures, as well as video quality metrics, to characterize new schedulers' performance improvements and interactions between network and application layers of video streams for various network scenarios.
