@GhostOnTheHalfShell @dlakelan @librecast @onepict Ghost: There is additional latency with IP multicast depending on the number of hops (routers), as the MLD join has to propagate. There are also delays on parting a group. MLD is not designed to be a low latency protocol and performs very poorly when there are lots of joins and parts.
IP multicast is very broken and there are no forms of IP multicast remaining that even meet Librecast's definition of "multicast" 😉 eg. SSM is *not* multicast.
