Enhancing QoE in HTTP/3 using EPS Framework

TL;DR

This paper proposes a novel scheduling and priority mapping framework for HTTP/3 that leverages EPS to significantly improve website QoE by optimizing resource delivery based on urgency and resource type.

Contribution

It introduces a mixed scheduling mechanism and an EPS priority mapping tailored to Chromium browser priorities, enhancing QoE in HTTP/3 networks.

Findings

Improved website load times and resource delivery efficiency.

Enhanced QoE metrics for complex websites with many resources.

Effective prioritization based on resource type and urgency.

Abstract

HTTP/3, the latest evolution of the Hypertext Transfer Protocol, utilizes QUIC, a new transport protocol leveraging UDP to overcome limitations such as connection time and head-of-line blocking prevalent in HTTP/2. This advancement is enhanced by the Extensible Prioritization Scheme (EPS), which introduces a flexible prioritization framework for improving website resource delivery. This paper proposes a mixed scheduling mechanism that delivers using mixed incremental and non-incremental resource delivery and adheres to EPS urgency levels to improve the QoE. Additionally, we propose an EPS priority mapping to enhance the QoE further. This mapping is based on the priority indicated by the Chromium browser and the resource type. The result of the experimental evaluation indicates that the proposed mechanism and mapping improve commonly-used website performance measures for sites featuring a comparatively large number and size of resources.
