Core Concepts
Adopting an urgency-based, non-incremental resource delivery method specified by the Extensible Prioritization Scheme (EPS) can improve the Quality of Experience (QoE) metrics across a range of websites compared to the default sequential scheduling.
Abstract
The paper explores the impact of prioritization on the QoE by employing an HTTP/3-based aioquic server, augmented with the EPS, within a controlled testbed. The authors propose two prioritization mapping strategies, Direct Mapping (DM) and Resource Type Aware Mapping (RTAM), and investigate their effects on the QoE across eight widely used websites.
The key findings are:
Adopting an EPS urgency-based non-incremental resource delivery method improves QoE compared to the default sequential scheduling provided by the standard aioquic server.
The RTAM mapping strategy further enhances the performance of metrics such as Largest Contentful Paint (LCP) and Speed Index (SI) compared to DM.
The performance improvements are influenced by the website structure and resource composition, with some websites experiencing more significant gains than others.
The authors also evaluate the impact under more challenging network conditions, observing consistent results.
The paper highlights the importance of practical prioritization strategies in enhancing web content delivery and user experience, particularly with the transition to the HTTP/3 protocol and the adoption of the EPS framework.
