We have numbers to share. We have performed two experiments at two different events LACNIC held this year: - June in Port-Au-Prince (~110 attendees) - October in Montevideo (~400 attendees) The question was: "What is the relation between IPv4 and IPv6 traffic in a fully dual-stacked network?". The answers were remarkably consistent. We got ~30% IPv6 in PAP and around 33% in MVD (actually in MVD we got over 40% in total byte counts, but we corrected for the IPv6 video feed that added a constant 1 Mbps/sec) This percentage is calculated as: 100*(bytes sent and received over IPv6) / (total bytes sent and received) In PAP we measured this using iftop and a couple of pcap filters on the Linux server we were using as 'router' (Owen was there and was of great help setting the whole thing up). In MVD we had a dual 7201s as routers and we measured traffic with Netflow. Warm regards, ~Carlos On 11/21/12 12:51 AM, Patrick W. Gilmore wrote:

If you assume that Youtube/Facebook/Netflix are 50% of the overall traffic, why wouldn't a dual stacked end point have half of its traffic as IPv6 after June???
"If you assume...". Kinda says it all right there.
But more importantly, those three combined are not 50% of overall traffic. It _might_ be true in the US, for some times of the day, but certainly not world-wide overall traffic. If for no better reason than you cannot get NF in all countries.
