摘要

虽然网络视频控制和数据平面受到了广泛的关注,但对视频管理平面的研究却很少。本文利用两年来一百多家视频出版商的数据,对视频管理平面及其演变进行了表征。管理平面在视频封装、播放设备支持和CDN使用方面显示出显著的多样性,目前的趋势表明这些方面的多样性正在增加。这种多样性增加了管理的复杂性,我们表明,许多管理任务的复杂性与出版商的内容被浏览的小时数呈次线性相关。此外,如今每个发布者都运行一个独立的管理平面,这种做法可能会导致联合内容的次优结果,例如CDN存储的冗余以及内容所有者对交付质量的控制丧失。

Understanding Video Management Planes
While Internet video control and data planes have received much research attention, little is known about the video management plane. In this paper, using data from more than a hundred video publishers spanning two years, we characterize the video management plane and its evolution. The management plane shows significant diversity with respect to video packaging, playback device support, and CDN use, and current trends suggest increasing diversity in some of these dimensions. This diversity adds complexity to management, and we show that the complexity of many management tasks is sub-linearly correlated with the number of hours a publisher's content is viewed. Moreover, today each publisher runs an independent management plane, and this practice can lead to sub-optimal outcomes for syndicated content, such as redundancies in CDN storage and loss of control for content owners over delivery quality.
