So the first user in a router tunes to a multicast stream. Consumption for the ISP and all the routers in the chain to the source: same as if it were a unicast stream. Then a second user tunes to a multicast stream. Cost for the ISP: zero.
How does this affect peering, when some providers want bandwidth ratios in a certain range? I can also see how this affects the ISPs providing bandwidth to the content providers. In our colo for example, we rate-limit customers to the paid-for bandwidth at the colo port. With multicast however, they could use significantly more bandwidth, because every router in our network could potentially send the stream to many ports. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
