Cascaded Foci (SFUs)
FOSDEM 2023

matrixRTC allows real time voice, video and data channels to be established between groups of people over Matrix, but what happens when those groups get large? In this talk, we’ll explore how matrixRTC uses cascading foci (Selective Forwarding Units, Multipoint Control Units,…) to ease bandwidth requirements for clients by relaying through servers in a federated and decentralised way.
