Well, as you say, we really don't have to overly complicate this wrt. Youtube IP traffic. I doubt anybody will argue that eyeballs have traffic to Google/Youtube traffic. How much? I remember some flow sample statistics from a few years back here from Gothenburg, covering some ~10k students with plenty of bandwidth. I assume these _swedish students_ knew how to use P2P. :) Google+Youtube was about 3rd or 4th unique origin AS by bytes transferred! I don't have the references available, but this I personally consider a ~fact for eyeball networks, at least in Scandinavia. Prove me wrong. :) I don't remember what this meant in terms of fraction of the total traffic, but I suspect somewhere around 5-10%? If what we want to find out is % IPv6 traffic out of all IP traffic, and how this might change by some large players, or protocols, (suddenly) changing behaviour, this is relevant. I assume the ranking of Google/Youtube has dropped much since then. More data needed. I could write more, but where I want to come basically boils down to that I strongly suspect that the current IPv6 support infrastructure for the transition mechanisms today do not support a Google/Youtube ceasing to use the DNS resolver whitelist method as a connectivity quality assurance technique. And I believe we will have to cope with the transition mechanisms for quite a while. We're a long way from native IPv6 to a majority of Internet users. But OS:s support transition and this is being "rolled out" every day, everywhere. So, the operator community should IMO continue to do more to help the transition. What would happen if $LARGE_FRACTION of p2p traffic suddenly moved to v6 transitions? This can happen. So it is, like you say Marco, not very significant how many % traffic there is today. There are much more important aspects to look at. I fully agree with you on this. Basically what to follow closely, I think boils down to something like: * users type of v6 connectivity, if at all * changes to p2p * changes to ~top-10 CDN:ish networks (youtube included) * rest of the web in general There are plenty previous work done in following/measuring several of these points. Would be nice with some potaroo.net type, stable, place to follow it, though.
