By using the server push of the hypertext transfer pro-tocol (HTTP) version 2.0, i.e., HTTP/2, along with the technique of server pacing, a novel scheme is proposed in this paper to deliver video segments. Furthermore, the load of bitrate adaptation is shifted to the server to avoid bandwidth competition and wastage caused by bitrate switching. It can be explicitly shown that no significant overhead is brought by our proposed scheme via complexity analysis. Moreover, our proposed scheme generates one HTTP request only. With extensive simulations, we successfully demonstrate that it is superior over the closely related schemes in terms of the average achievable bitrate, the number of buffer stalls, the ratio of unclaimed pushes, etc., in particular, when a harsh network condition arises.

通过HTTP / 2的视频流：自适应服务器定速推送的设计和评估

通过使用服务器推送的超文本传输​​协议（HTTP）版本2.0，即HTTP / 2，以及服务器调速技术，本文提出了一种新颖的方案来传送视频片段。此外，将比特率自适应的负载转移到服务器上，以避免带宽竞争和比特率切换导致的浪费。可以明确地表明，我们提出的方案通过复杂性分析不会带来显着的开销。此外，我们提出的方案仅生成一个HTTP请求。通过广泛的仿真，我们成功地证明了它在可达到的平均比特率，缓冲区停顿的数量，无人认领的推送的比率等方面优于紧密相关的方案，尤其是在出现恶劣的网络条件时。
