Haopeng Zhang, Ming Jiang, Jinquan Nie, Yuehua Fan, Yuanlong Cao · 2024
The deployment of multipath transmission protocols has brought opportunities for the development of data-intensive network applications such as mobile ultra-high-definition video and provides solutions for maximizing the utilization of diverse and long-coexisting network resources like Wi-Fi, 4G, etc., under 5G scenarios, as well as for achieving network load balancing. However, most research on multipath scheduling mainly focuses on improving the performance of wired networks, and the importance of Multipath QUIC (MPQUIC) path-scheduling strategies for wireless transmission has not been given sufficient attention. This paper proposes MPSI; by combining mechanisms such as Signal Interference Noise Ratio (SINR), Round-Trip Time (RTT), and weighted freshness, it not only significantly optimizes the transmission efficiency and stability of web video streams under wireless networks but also ensures fair resource allocation among substreams during multipath transmission. It provides an effective solution to the challenges of multipath wireless transmission in weak network environments. Experimental results indicate that compared to traditional multipath scheduling algorithms, MPSI demonstrates significant improvements in throughput and robustness.
