[ipv6-wg] Youtube over IPv6!

Interesting discussion, and some new hypotheses.
I am doing some research on the side to figure out how to best measure IPv6 progress.

>From the quantitative angle, the size of your network hardly matters. A six fold increase (sic) is still a six fold increase. At CSBnet is goes from 1 Mbit/sec to 6 Mbit (roughly), at DE-CIX it goes from 0.3 Gbit to 1.8 Gbit.

More interesting is the IPv6 fraction. At DE-CIX this has risen six fold to 0.16% of total traffic (roughly), while at the AMS-IX it is steady at 0.17%.

As the total traffic levels at these exchanges are comparable (around 0.6 Terabit/sec avg) I have the idea that we need two hypotheses.
As Marco suggests the AMS-IX may have traditionally carried a lot of IPv6 netnews, which explains its early lead. My other hypothesis is that the youtube traffic is privately peered outside of the amsix statistic, because Google has datacenters in the Netherlands (I have other research to support that). 

Martin, could you comment on your current IPv6 fraction?

In all cases, daily patterns suggest that home users are dominant, even before Youtube got on IPv6.

Anyone to comment on these ideas?

Regards.

Our graph is IMHO quite appropriate for an eyeball-only leaf network, as that is what we are.  Even if we only have a meager 2000 customers, an
*extremely* high percentage of these are IPv6-enabled (much due to a very high turnover rate, meaning new students with new capable OS's move in frequently). We are way past 50% of our users IPv6 enabled by now. 

So, for the eyeball side of it all, and if you are whitelisted, I would wager that the increase seen in our graph is ~quite representative of what type of impact it can have in a (even dormitory) network with high IPv6-stack ratio.

Having said that, there wasn't much to see on v6 before. And most peer to peer connections still carry most data over v4.  This is something I suspect 2010 might see heavy change of though. Stay alert and be prepared to relay!

I'm well aware 1000-1500 IPv6 clients isn't much of a statistical base on the full Internet scale... so, more data would be interesting, including such from Google.
