Abstract

Video conferencing has become a daily necessity, but protocols to support video conferencing have yet to keep pace despite the innovation in next-generation networks. As video resolutions increase and mobile applications using multiple cameras for photos and videos become popular, the need to meet the Quality of Experience (QoE) requirements is growing. Multipath protocols could be a possible solution.

In this paper, we show that a straightforward extension of WebRTC for supporting multipath can perform worse than legacy WebRTC and propose Converge, a WebRTC-compliant multipath video conferencing platform. Converge improves QoE through three main components: a video-aware scheduler, video QoE feedback, and video-aware and path-specific packet protection. The video-aware scheduler uses the real-time video structure to schedule packets, and the video QoE feedback from the receiver helps the scheduler adjust the number of packets on each path. Additionally, the video-aware and path-specific packet protection mechanism improves on the existing FEC mechanism in WebRTC by considering the trade-off between FEC and QoE. Converge is built as part of the Chromium browser, making it compatible with any device or network path. Converge improves overall media throughput by 1.2×, reduces end-to-end latency by 20%, and enhances image quality by 55% compared to WebRTC.

Improved Jitter Buffer Management for WebRTC

This work studies the jitter buffer management algorithm for Voice over IP in WebRTC. In particular, it details the core concepts of WebRTC’s jitter buffer management. Furthermore, it investigates how jitter buffer management algorithm behaves under ...
Optimizing Real-Time Video Experience with Data Scalable Codec
EMS '23: Proceedings of the 2023 Workshop on Emerging Multimedia Systems

Real-time video communication is becoming more and more important. However, packet loss is prevalent and resending packets, especially in long-latency networks, causes visual stalls. Previous solutions all perform suboptimally as they either add ...
Improving QoE Using a Novel Multipath Routing Based on Source and Intermediate Node Forwarding
ICFN '10: Proceedings of the 2010 Second International Conference on Future Networks

This paper proposes a simple and effective algorithm to improve the quality of service on the Internet by providing alternate path between source and destination nodes when the delay or packet loss rate on the primary path becomes unacceptable. We ...
