Multicast with multiple senders for the same Multicast group.

[leo.hardy]

We are implementing a Nortel Telephony application called "web client".

In our shop we have 2 SL1 on 2 sites 150 miles away. On each site we have a Symposium Server.

The application model suggest that each Symposium server Multicast informations using the same "multicast group number", lets number it 233.n.n.1.

A "web client server" is listening this multicast group 233.n.n.1, which theoricaly come from multiple Symposium servers, and then reformat the informations and forward it to the "host CLients" via the multicast group 233.n.n.2.

Is it a model that will work?? For me it seems strange that a "host" received, for the same multicast group, data from many sources!!!

Thank for your help!!

Leo,

As long as the hosts generating the multicast traffic have unique IP addresses, the application should be able to differentiate between the data.
