SFU (Selective Forwarding Unit), explained
The three ways to run a group call differ in where the work happens. Peer-to-peer sends every participant’s stream to every other participant directly, which is simple and collapses past a handful of people. An MCU decodes all the streams, composites them into one and sends a single stream out, which is cheap for the client and extremely expensive for the server. An SFU sits between: it forwards without transcoding, so server cost stays modest while clients receive separate streams they can lay out as they like.
How Enclessa uses it
Enclessa uses LiveKit as its SFU. Enclessa publishes no measured figure for the largest call it has run: the load harness for the fifty-person target exists, and the test itself has not been run, so no number is claimed. The design target is a fifty-person meeting with screen sharing for sixty minutes, which is a target rather than a measurement.
