Subject Multicast transport actually udptransport for broadcast?
Date Tue, 15 Dec 2009 16:15:07 GMT

I'm new to the project, so forgive me for my ignorance.

It appears as though the multicast transport isn't working as expected. I do
see messages go from publisher all the way to subscriber but not on the
multicast group.

I have a pub/sub setup whereby the clients are connecting to a broker using
multicast transport. I see the broker accept the consumer (I can see these
udp packets belonging to the correct group), but it then sets up a Udp
transport (via the UdpTransportServer running in the broker) that sends
directed udp back to the client. I was expecting that the broadcast to the
consumers would be a single multicast broadcast instead of directed udp.

I'm running 5.3, however looking back through the versions it doesn't appear
that multicast was ever sending correctly. Can someone else who is more
familiar with the code confirm this? Perhaps I've configured something
wrong.

Also, is anyone using multicast in production?
