I am thinking of switching our streaming servers to use multicasting instead of registering multiple clients and duplicating the streams manually on the server. It seems to work very well. However, I did notice that on the packet capture, when a server is multicasting the packets show up on every node, even those that have not subscribed to the stream. Is this the way it is supposed to function? Will this cause network problems if I have several of these servers sending out a multicast stream simultaneously(to different addresses obviously)?
