Yes, but the IP headers are the same in all of them. > Many of the original uses for multicast are now dominated by unicast packet duplication with edge computing making this less of a bandwidth hog, so it is not clear what the long term future of multicast is. Not on Wall Street. But you will say that is domain specific, and that's okay. Should we really be building an IP header or have semantics on an IP header for different domains? Dino
