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.
