HTTP/2 video streaming has caught a lot of attentions in the development of multimedia technologies over the last few years. In HTTP/2, the server push mechanism allows the server to deliver more video segments to the client within a single request in order to deal with the requests explosion problem. As a result, recent research efforts have been focusing on utilizing such a feature to enhance the streaming experience while reducing the request-related overhead. However, current works only optimize the performance of a single client, without necessary concerns of possible influences on other clients in the same network. When multiple streaming clients compete for a shared bandwidth in HTTP/1.1, they are likely to suffer from unfairness, which is defined as the inequality in their bitrate selections. For HTTP/1.1, existing works have proven that the network-assisted solutions are effective in solving the unfairness problem. However, the feasibility of utilizing such an approach for the HTTP/2 server push has not been investigated. Therefore, in this paper, a novel proxy-based framework is proposed to overcome the unfairness problem in adaptive streaming over HTTP/2 with the server push. Experimental results confirm the outperformance of the proposed framework in ensuring the fairness, assisting the clients to avoid rebuffering events and lower bitrate degradation amplitude, while maintaining the mechanism of the server push feature.

FAURAS:一种基于代理的框架,用于确保通过 HTTP/2 服务器推送的自适应视频流的公平性

在过去几年中,HTTP/2 视频流在多媒体技术的发展中引起了很多关注。在 HTTP/2 中,服务器推送机制允许服务器在单个请求内向客户端传送更多的视频片段,以处理请求爆炸问题。因此,最近的研究工作一直专注于利用这种特性来增强流媒体体验,同时减少与请求相关的开销。然而,目前的工作只是优化单个客户端的性能,没有必要担心对同一网络中其他客户端的可能影响。当多个流媒体客户端在 HTTP/1.1 中竞争共享带宽时,它们很可能会遭受不公平,这被定义为比特率选择的不平等。对于 HTTP/1.1,现有工作已经证明网络辅助解决方案在解决不公平问题方面是有效的。但是,尚未研究将这种方法用于 HTTP/2 服务器推送的可行性。因此,在本文中,提出了一种新颖的基于代理的框架来克服服务器推送在 HTTP/2 上的自适应流中的不公平问题。实验结果证实了所提出的框架在确保公平性、帮助客户端避免重新缓冲事件和降低比特率降级幅度方面的优异性能,同时保持了服务器推送功能的机制。提出了一种新颖的基于代理的框架,以克服服务器推送通过 HTTP/2 进行自适应流传输的不公平问题。实验结果证实了所提出的框架在确保公平性、帮助客户端避免重新缓冲事件和降低比特率降级幅度方面的优异性能,同时保持了服务器推送功能的机制。提出了一种新颖的基于代理的框架,以克服服务器推送通过 HTTP/2 进行自适应流传输的不公平问题。实验结果证实了所提出的框架在确保公平性、帮助客户端避免重新缓冲事件和降低比特率降级幅度方面的优异性能,同时保持了服务器推送功能的机制。
