Bisecting Browser Bugs (Arne Georg Gisnås Gleditsch)

Being able to quickly identify what exactly broke is key to either preventing a regression from landing in Chrome Stable or adapting your own code to avoid the problem. Chrome’s bisect-builds.py tool makes this process much easier than you would suspect. Arne […]
Improving Scale and Media Quality with Cascading SFUs (Boris Grozev)
Deploying media servers for WebRTC has two major challenges, scaling beyond a single server as well as optimizing the media latency for all users in the conference. While simple sharding approaches like “send all users in conference X to server Y” are easy to scale horizontally, they are far from optimal in terms of the […]
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 […]
