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.
You are billing your content provider for the bandwidth consumption at his port not because you intend to bill him for the bandwidth of content provided, but for the bandwidth of content delivered to the end user! The end-user is ALREADY PAYING for that bandwidth! Something is *really* broken there. -- Octavio. Twitter: @alvarezp2000 -- Identi.ca: @alvarezp
