Evaluating Edge-Termination Buffer Effects for Real-Time AV1 over MPEG2-TS over HTTP/3 QUIC

This technical note presents experimental evaluations and architectural considerations for real-time AV1 over MPEG-TS streaming using HTTP/3 QUIC with a focus on edge-termination buffer design and fairness-aware resource utilization. Building upon prior implementation of QUIC protocol stacks (ngtcp2, nghttp3) and smartphone applications, we investigate how edge buffer saturation and silent packet drops affect end-to-end video quality (QoS) across multi-region cloud deployments. In addition, we propose a complementary mechanism that integrates QUIC DATAGRAM with 2D Forward Error Correction (FEC) and three-state FIFO bitmaps to enable session-level flow control, real-time adaptive bitrate (ABR), and fair charging in wireless environments. Our results indicate that edge-side buffer design has greater influence on QoS than congestion control algorithms, and that real-time session stop/restart driven by application-layer ACKs can significantly reduce wasted wireless resources while ensuring fairness in charging only for decodable packets. This work aims to provide practical design insights into low-latency, scalable live streaming systems over cloud and edge infrastructures.
