Re: Multicast Traffic on Backbones

HOWEVER, most of the 24x7 media sites (CNN, etc.) are doing on-demand video, rather than streaming a constant feed.

1) rights 2) unicast doesn't scale to the sort of audiences of radio/tv broadcasts and if you try it becomes financially unviable too (even with people attempting to fake multicast, e.g. Akamai) One way to manage both is to use the VCR model

On the one hand, content providers aren't offering 24x7 multicast feeds because there isn't enough multicast access at the end-points.

We offer it regardless but there's not many can use it

Apart from 24x7 broadcast there isn't an obvious killer app.

And there's reasonable argument over making the intenet = tv brandon
