Simon is correct. The numbers I quoted were for protocol 41 traffic, and presumably more IPv6 is "hidden in plain sight" on the Internet 2 backbone. Sorry for the confusion. Regards Marshall
While I'm also skeptical about the representativeness of Jordi's estimates, this is a bad counterexample (see below about why):Netflow on Internet 2 for last weekhttp://netflow.internet2.edu/weekly/20050829/has 6.299 Gigabytes being sent by IPv6, out of a total 383.2 Terabytes, or 0.0016% This is backbone traffic, and would not catch intra-Campus traffic, nor would it catch tunnel or VPN traffic,^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^ Wrong. What you see here is ONLY tunnel traffic, because the number is for IPv6-in-IPv4 (IP protocol 41) traffic. Netflow for IPv6 isn't widely used yet. Our own equipment doesn't support it, and I don't think the Junipers used in Abilene do, either (someone please correct me if I'm wrong).but it is suggestive.Yes, but it's also irrelevant, because Abilene has native IPv6, so there is little incentive for sending IPv6 tunneled in IPv4.According to the graph http://netflow.internet2.edu/weekly/longit/perc-protocols41-octets.png the most I2 IPv6 traffic was in 2002, when it was almost 0.6% of the total.I would assume that that was before IPv6 went native on Abilene.It is hard for me to imagine that the situation for commerical US traffic is much different.I'm sure there's lessThere may be similar statistics for Geant - I would be interested to see them.I'll look up the GEANT numbers in a minute, stay tuned. -- Simon.
