multicast: video streaming^mkt data

These are the 2 main usages of IP multicast. In both, Lost packets are considered lost forever. Resend is sometimes considered “too late”.

I think some of the world’s most cutting-edge network services — live price feed, live event broadcast, VOD, multiplayer gaming — rely on multicast.

Multicast is more intelligent data dissemination than broadcast, and faster than unicast. Intelligence is built into routers.

I believe JMS publish is unicast based, not broadcast based. The receivers don’t comprise an IP broadcast group. Therefore JMS broker must deliver to one receiver at a time.
