HTTP/WebSocket relies on a stateful connection! Man that strikes me as so not smart! Comedically, UPnP was also HTTP, but not as stateful as websockets. Often httpu, http over UDP. And for service discovery, httpu over multicast, pretty much like mdns. I'm surprised that s2 would have broken, given that I'd expect s1 to also need multicast. Maybe Sonos setup a pinhole router via upnp-igd, so devices could talk to each other inside the network, even if multicast was off? It's be interesting to know if any upnp-igd rules were created in s1. |
