[BC] RE: Multiple ISDN

[Tom Hartnett]

Hi Dana,

I suspect there may be some confusion here. Whether a stream is UDP or TCP,
there's no inherent broadcast protocol built in. To distribute streams to
more than one place, one can either:
1) Multistream--build an independent udp or tcp unicast stream to each user.
This is how virtually all streaming servers work, including your Barix and
our ACCESS. ACCESS is specified to deliver 9 streams in all modes, but can
do over 50 in some modes. Note to do 50 streams you need 50x upload
bandwidth.
2) IP Multicast-- Build one stream and send it to a special multicast
address. Receivers will also attach to a special multicast address and get
their streams, but it is distributed by the network. By and large, most
publicly available Internet *does not* support IP Multicast, although it is
supported in ACCESS for use on LANS and WANS.

Best
