Abstract

WebRTC capable media servers are ubiquitous, and among them, Selective Forwarding Units (SFU) seem to generate more and more interest, especially as a mandatory component of WebRTC 1.0 Simulcast. The two most represented use cases implemented using a WebRTC SFU are video conferencing and broadcasting. To date, there has not been any scientific comparative study of WebRTC SFUs. We propose here a new approach based on the KITE testing engine. We apply it to the comparative study of five main open-source WebRTC SFUs, used for video conferencing, under load. The results show that such approach is viable, and provide unexpected and refreshingly new insights on the scalability of those SFUs.
面向视频会议的WebRTC开源sfu的比较研究
支持WebRTC的媒体服务器无处不在,其中,选择性转发单元(SFU)似乎引起了越来越多的兴趣,特别是作为WebRTC 1.0联播的强制性组件。使用WebRTC SFU实现的两个最具代表性的用例是视频会议和广播。迄今为止,还没有对WebRTC sfu进行科学的比较研究。本文提出了一种基于KITE测试引擎的新方法。我们将其应用于五种主要用于视频会议的开源webbrtc sfu在负载下的比较研究。结果表明,这种方法是可行的,并且为这些sfu的可伸缩性提供了意想不到的、令人耳目一新的见解。
