  21. 21. What affects the timing for IPv6? Global IP and VPN Services
  22. 22. What Affects the Timing for IPv6? <ul><li>Whether we should go for IPv6 is not a question, the question is when we should move to IPv6 </li></ul>Global IP and VPN Services Deadline Lead-time Right time?
  23. 23. Did our early emphasis on IPv6 pay off? <ul><li>Visibility, early mover advantage and differentiator in the marketplace </li></ul><ul><ul><li>If carrier A offers IPv4 only and carrier B offers both IPv4 and IPv6, other criteria being similar, who would a tier 2 ISP carrier base go for? </li></ul></ul><ul><ul><li>40+ of our major customers connect in both IPv4 and IPv6 </li></ul></ul><ul><li>IPv6 support is becoming a must to win a bid </li></ul><ul><ul><li>Of around 60 major RFQ’s for IP transit answered both in 2006 and 2007, about 50 included questions on IPv6 support, roughly half gave points to IPv6 support in their response evaluation and 10 had IPv6 support as mandatory or exclusion factor if not compliant. </li></ul></ul><ul><li>Next step: stimulate growth of the IPv6 component of the overall IP traffic. </li></ul>Global IP and VPN Services
