While talking about the venue management tool it would be nice to
be able to restrict it to a single IP address for multicast (and just
let it dynamically assign ports). As it is, the mask only allows for
0-31, where I need '32' in order to lock it down as such. I was given
two addresses but they do not fit within one /31 CIDR range (of
course :>).
Derek,
There may be problems for clients when using that strategy (using a
single IP, but different ports for different venues) for bandwidth
challenged clients. Even when they're only connected to a single
venue, the traffic from all the other venues sharing the same IP
address would flow to the client as well. A client can filter based on
port number, but all other (unwanted) traffic on the same IP address
has also arrived regardless of using a different port (only to be
filtered out anyway). Using different multicast IP addresses means
that only the requested streams flow to the client. In fact, we now
configure our server to use different IP addresses for audio & video
in the same venue.
