With the increasing popularity of video services, HTTP adaptive streaming (HAS) has become the mainstream technology for media streaming distribution. In traditional HAS over HTTP/1.1, the HAS server responds to each request from the client individually. This process adds additional round-trip time, resulting in underestimation of available bandwidth. As a result, the HAS client chooses a lower bitrate, which reduces network utilization and the user's quality of experience. In recent years, the HTTP/2 protocol has emerged, which allows server to actively push multiple data segments to the client. Pushing multiple segments can reduce the negative impact of network latency on estimating available bandwidth, thereby increasing the user's request bitrate and video quality. However, when the network is unstable, the more video segments that are pushed by the server, the more challenges the client encounters in responding to network fluctuations i n t ime, c ausing playback stalling and poor user experience. Therefore, this paper proposes a dynamic server push algorithm over HTTP/2, which chooses a different number of segments for server push according to network fluctuations. F or t he e valuation r esults, r elative t o its benchmarks, the proposed approach improves the average video request bitrate while minimizing the probability of playback stalling. |
