AI总结：
本文提出基于可扩展优先级方案（EPS）的加权增量Web内容交付机制，增强HTTP/3顺序调度以提供增量资源交付，实验证明其能提升Lighthouse测量的体验质量（QoE），但QoE对网页结构等因素敏感。
摘要：
随着QUIC这一现代传输层网络协议的引入，HTTP/3利用其优势来增强Web内容交付。本文提出了一种基于最近标准化的可扩展优先级方案（EPS）的机制，用于加权增量Web内容交付。该机制增强了顺序调度，以提供增量和加权增量资源交付。使用所提出的机制扩展现有的HTTP/3实现，并用八个流行网站的内容进行了测试。我们的实验分析结果表明，加权增量优先级改进了由标准QoE测试工具Lighthouse测量的体验质量（QoE）。虽然通常实现了总体改进，我们也观察到少数情况下性能略有下降，突出了QoE对网页结构等因素的敏感性。
英文摘要：
With the introduction of QUIC, a modern transport-layer network protocol, HTTP/3 leverages its benefits to enhance web content delivery. This paper proposes a mechanism based on the recently standardized Extensible Prioritization Scheme (EPS) for weighted incremental web content delivery. The mechanism augments the sequential scheduling to provide incremental and weighted incremental resource delivery. An existing HTTP/3 implementation was extended with the proposed mechanism and tested with the content of eight popular websites. The results of our experimental analysis show that weighted incremental prioritization improves Quality of Experience (QoE) as measured by Lighthouse, a standard QoE test tool. While overall improvements were generally achieved, we also observed a few cases where the performance degraded slightly, highlighting that the QoE is sensitive to factors such as web page structure.
