Abstract

As short video applications gain popularity, researchers are exploring ways to enhance Quality of Experience (QoE) for short videos while maximizing network bandwidth efficiency. Despite the growing interest, existing Adaptive Bitrate (ABR) algorithms primarily concentrate on content prefetching strategies and often overlook the dynamic interaction between network congestion control and ABR. This interaction is especially critical for short video streaming, where network conditions can fluctuate rapidly, and user expectations for seamless playback are high. To address these challenges, we propose aCroSS, an AI-driven framework for adaptive short video streaming that jointly optimizes both the application and transport layers to enhance QoE and bandwidth utilization. The aCroSS algorithm leverages advanced machine learning techniques to adapt in real time to fluctuating network conditions and dynamic user behaviors, delivering a more robust and responsive streaming experience. Our simulation results demonstrate that aCroSS consistently outperforms existing baseline algorithms, achieving more than a 10% improvement in utility scores across various network trace datasets. This highlights the effectiveness of aCroSS in delivering superior performance in diverse streaming environments.

aCroSS:面向短视频应用的人工智能驱动跨层自适应流媒体技术
随着短视频应用的普及,研究人员正在探索如何提高短视频的体验质量(QoE),同时最大限度地提高网络带宽效率。尽管兴趣与日俱增,但现有的自适应比特率(ABR)算法主要集中在内容预取策略上,往往忽略了网络拥塞控制与 ABR 之间的动态交互。这种互动对于短视频流来说尤为重要,因为短视频流的网络条件可能会快速波动,而用户对无缝播放的期望值很高。为了应对这些挑战,我们提出了 aCroSS,这是一个人工智能驱动的自适应短视频流框架,它能联合优化应用层和传输层,以提高质量和带宽利用率。aCroSS 算法利用先进的机器学习技术,实时适应波动的网络条件和动态的用户行为,提供更稳健、响应更快的流媒体体验。我们的模拟结果表明,aCroSS 的性能始终优于现有的基线算法,在各种网络跟踪数据集上的实用性得分提高了 10%以上。这凸显了 aCroSS 在各种流媒体环境中提供卓越性能的有效性。
