Abstract

With the increased use of video conferencing platforms in recent times, the quality of the provided service has become extremely important. The exchange of data, including audio and video, among participants in a video conference relies on a series of mechanisms and protocols that must function correctly to prevent communication degradation. This study examines the behavior of WebRTC-based video conferencing platforms when subjected to bandwidth restrictions. In this iteration, an analysis is conducted on the Elos and Google Meet platforms, using a cross-layer indicator-based approach for video conferencing service quality monitoring. The results indicate that the platforms employ distinct approaches to handle scenarios of limited network capacity. By deepening the understanding of these different adaptation strategies, this study contributes to the development of new quality adaptation strategies and provides support for research focused on evaluating QoE in video conferencing platforms.
