Jashanjot Singh Sidhu, Jorge Ignacio Sandoval, Abdelhak Bentaleb, Sandra Cespedes

TL;DR
This paper analyzes how modern queue management strategies and their interactions with QUIC, congestion control, and adaptive streaming affect video quality in 5G networks, emphasizing the need for cross-layer optimization.
Contribution
It provides a comprehensive analysis of AQM strategies' impact on QUIC-based video streaming over 5G, highlighting the importance of cross-layer adaptive mechanisms.
Findings
AQM strategies' effectiveness depends on their interaction with QUIC and congestion control.
Isolated optimizations are insufficient for optimal video QoE in 5G networks.
Cross-layer adaptive mechanisms are crucial for high-quality video streaming.
Abstract
The rapid adoption of QUIC as a transport protocol has transformed content delivery by reducing latency, enhancing congestion control (CC), and enabling more efficient multiplexing. With the advent of 5G networks, which support ultra-low latency and high bandwidth, streaming high-resolution video at 4K and beyond has become increasingly viable. However, optimizing Quality of Experience (QoE) in mobile networks remains challenging due to the complex interactions among Adaptive Bit Rate (ABR) schemes at the application layer, CC algorithms at the transport layer, and Radio Link Control (RLC) queuing at the link layer in the 5G network. While prior studies have largely examined these components in isolation, this work presents a comprehensive analysis of the impact of modern active queue management (AQM) strategies, such as RED and L4S, on video streaming over diverse QUIC…
