Hi,

Good catch Gabriel, to detect the right link (https://www.irif.fr/~jch/software/sfu/) behind SFUs word "we evaluated many open source SFUs"!

Have a good day
Phil

Dear all,

Galène is mentioned (well, linked to) in the following article:

https://signal.org/blog/how-to-build-encrypted-group-calls/

TL;DR: Signal needed an SFU with good congestion control and scaling properties. They evaluated a number, found that only jitsi and mediasoup had good enough congestion control at the time (it was over a year ago), picked one but it used too much CPU so they wrote their own in Rust. The article gives a lot more technical details about their implementation, but doesn't delve into the evaluation of other solutions.

Best regards,
