  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.
