P2P multiparty videoconferencing just isn't realistic outside of tech demos. In a call of 20 participants, someone with a typical 720p webcam would be transmitting more than 50Mbit/s, which doesn't sound like a lot when ISPs market so-called "1Gbit fibre", but in fact is more than a lot of residential connections and home Wi-Fi can reliably push without unacceptable loss/delay/jitter.
A product built with this architecture could not deliver the reliability and performance that Zoom delivers with the variety of connectivity quality that its users have.
- ninkendo 5y agoI wonder if WebRTC will ever support Multicast IP (or maybe explicit multi-unicast) so that you only need to upload one copy of your signal. Something tells me the various consumer routers out there wouldn't know how to deal with the traffic...
- toast0 5y agoWebRTC can support it all they want, but to a first approximation, Multicast doesn't work over the open internet, so it won't help outside of corporate videoconference (which generally runs OK, because corporate networks are mostly wired and often overprovisioned or easier to provision than homes)
- detaro 5y agoconsumer routers are not the main problem with that (they might even support multicast, because various ISPs use it to distribute TV channels) - the public internet generally has no way of handling it.
