webrtcH4cKS: ~ Breaking Point: WebRTC SFU Load Testing (Alex Gouaillard)
If you plan to have multiple participants in your WebRTC calls then you will probably end up using a Selective Forwarding Unit (SFU). Capacity planning for SFU’s can be difficult – there are estimates to be made for where they should be placed, how much bandwidth they will consume, and what kind of servers you need.
To help network architects and WebRTC engineers make some of these decisions, webrtcHacks contributor Dr. Alex Gouaillard and his team at CoSMo Software put together a load test suite to measure load vs. video quality. They published their results for all of the major open source WebRTC SFU’s. This suite based is the Karoshi Interoperability Testing Engine (KITE) Google funded and uses on webrtc.org to show interoperability status. The CoSMo team also developed a machine learning based video quality assessment framework optimized for real time communications scenarios.
