You would use different multicast addresses for different streams and would serve the requests from multiple devices. For example, if your multicast server can handle 10 streams and you needed to serve out 20 streams then you would configure two servers on two (or more) different multicast addresses. Clients would access the appropriate address for the desired stream. None of this is possible with haproxy. It may be possible to use heartbeat, LVS or similar to manage multicast service addresses if you have a need to move them between different devices for failover. This may be done by starting/stopping a service which listens to / broadcasts from the address rather than directly manipulating the IP address in a traditional fashion. -JohnF
