Anything that is "live" & likely to be watched by lots of people at the same time like sports can handled via multicast. The IPTV guys have had a number of years to get that work fairly well in telco environments. The content that can't be handled with multicast, like on demand programming, is where you lose your economy of scale.Sunday Night Football at the top last week, with 7.1% of US homes watching. That's over 23 times as many folks watching as the 0.3% in our previous math! Ok, 23 times 150Gbps. 3.45Tb/s. Yowzer. That's a lot of data. 345 10GE ports for a SINGLE TV show. But that's 7.1% of homes, so scale up to 100% of homes and you get 48Tb/sec, that's right 4830 simultaneous 10GE's if all of Comcast's existing high speed subs dropped cable and watched the same shows over the Internet. I think we all know that streaming video is large. Putting the real numbers to it shows the real engineering challenges on both sides, generating and sinking the content, and why comapnies are fighting so much over it.
