How we do this isthe question, i.e. what form the "multi"-"casting" takes.It would be nice if we could take advantage of an inherent design of IP and the hardware it runs on, to duplicate the actual packets in-flow as near asis required to the destination.Installing L7 content delivery boxes or caches is OK, but doesn't seem asefficient as an overall technical solution.work today. If it did work, then our next hurdle would be, how to get tier1 to playball, they get money on bits transported, it's not in their best interestedto reduce that amount.Any eyeball network that wants to support multicast should peer with the content players(s) that support it. Simple!Just another reason to make the transit only networks even more irrelevant.
The big issue is that the customers don't want to watch simulcast content. The odds of having two customers in a reasonably sized multicast domain watching the same netflix movie at exactly the same time frame in the movie is slim. Customers want to watch on time frames of their own choosing. I don't see multicast helping at all in dealing with the situation.
