CAQ: Connection-Aware Adaptive QUIC Configurations for Enhanced Video Streaming
Bibliographic record
Abstract
QUIC is rapidly emerging as the de facto standard for video streaming, particularly with the advent of 5G technology enabling the delivery of high resolution 4K content. However, sudden fluctuations in network capacity between 4G and 5G networks can occur due to various factors, such as network congestion, user mobility, or physical obstructions, leading to rapid changes in available bandwidth, which pose significant challenges for HTTP Adaptive Streaming (HAS) sessions that rely on more stable data rates for smooth playback, often resulting in interruptions and degraded Quality of Experience (QoE). Furthermore, current QUIC implementations are characterized by static configuration parameters, including constant pacing rates and static buffer sizes. This rigidity limits the server's ability to adapt dynamically to the client's real-time network conditions, making it challenging to prevent playback stalls and improve user QoE. To address these issues, we propose Connection-Aware QUIC (CAQ), which utilizes encrypted client playback statistics to dynamically adjust server parameters and implement an adaptive pacing rate. This approach aims to optimize streaming performance and enhance user experience, even in highly fluctuating network conditions. To evaluate the performance of CAQ, we conduct a series of trace-driven experiments across two key streaming modes: Video-on-Demand (VoD) and Low-Latency Live (LLL). Experimental results demonstrate that CAQ improves the VMAF by ~4%, QoEyin by ~41% while reducing rebuffering duration by ~8% for VoD mode and improves the VMAF by ~7%, QoEyin by ~49% with comparable rebuffering for LLL mode.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
