Multicast won't be useful if your routers don't support it. Similarly,
since you mentioned "internetradio" it won't be useful at all, because
very few of the internet's routers support it.


well, it might be that some internet routers still do not support Multicast.
We have checked with our providers, and they confirmed, all routers are
multicast enabled -we did a test stream with mc-only and it worked.

Yes but *downstream* they aren't, which brings me back to the point
that unless you can get to the next to last hop to the media consumer,
trying to use multicast just moves the content distribution bottleneck
down a little.

Rather more usefully, Try running at the command line

pathping -T -R

between a (remote) IP and your systems. You should be able to see both
QOS support on the routed path, and parts of the internet which are
routing with high latency (PING tests aren't diagnostic because they
use a different network protocol, but it's a good first approximation)


Nevertheless, we would like to provide multicast, because in case of
problems there should still be unicast rollover possible, isn't it?
But maybe this question should be addressed to the SAM-Developers, because
it creates the publishing point itself.


You probably need to follow thes steps listed here :

Yes, indeed, that helped a lot. Some features aren't visible at the first
look ;-)

Thanks and regards
