Sorry, but are your eyeballs not already paying you for that bandwidth that they are consuming. Multicast merely optimises that across your network. You have 200,000 eyeballs all watching the royal wedding on youtube, at 2Mbps per stream. or You have 200,000 eyeballs all watching the royal wedding on multicast, with no more than one copy of 2Mbps going over each of your backbone links. I know which one I'd prefer. The only place it causes some confusion over charging is if you're the content ISP which is originating the multicast. How do you charge your TV Channel customer? Sure, it won't be 2Mbps at your normal per Mbps rate, but equally it won't be 2Mbps * the number of end users watching the stream. It'll be somewhere in the middle, probably tending far more towards the 2Mbps end. Simon
