    1. 1. The Evolution from IPv4 to IPv6/IP Next Generation: Opportunities and Challenges Telecommunications Systems & Software Group Irish National IPv6 Centre June 11, 2008
    2. 2. Agenda <ul><li>The need to fill in the depleting IPv4 address space </li></ul><ul><li>The need to expand addressing capacity to cater for Internet growth and sustainability </li></ul><ul><li>Improved features in IPv6: Auto-configuration, QoS, built-in security, multicast and mobility </li></ul><ul><li>Presenting real IPv6 deployment showcases and moving adoption forward </li></ul>
    3. 3. Recent Developments <ul><li>27/5/08 European Commission Issues a Communication promoting IPv6 http://ec.europa.eu/information_society/policy/ipv6/docs/european_day/comm-ipv6-final_en.pdf </li></ul><ul><li>7/3/08 OECD issues an Economic Report on the IPv4 to IPv6 transition http://www.oecd.org/dataoecd/7/1/40605942.pdf </li></ul>
    4. 4. Benefits of IPv6 <ul><li>More IP Addresses IPv6: 2 128 ≈ 3 x 10 38 IPv4: 2 32 ≈ 4 x 10 9 </li></ul><ul><li>Only 15% of the IPv4 addresses have not been allocated. (39 out of 256 blocks) </li></ul><ul><li>http://www.ipv6forum.com/ipv4_exhaustion.php </li></ul>
    5. 5. Benefits of IPv6 http://www.iana.org/assignments/ipv4-address-space
    6. 6. Benefits of IPv6 Taken from http://www.potaroo.net/tools/ipv4/index.html - being used by RIPE
    7. 7. Benefits of IPv6 <ul><li>More IP Addresses </li></ul><ul><li>Workaround is NAT. </li></ul><ul><ul><li>Additional work and maintenance. </li></ul></ul><ul><ul><li>No P2P applications. </li></ul></ul><ul><ul><li>Two levels of internet citizen. </li></ul></ul>
    8. 8. Benefits of IPv6 <ul><li>Quality of Service </li></ul><ul><li>IPv4 ToS is little used – delays. </li></ul><ul><li>IPv4 contains </li></ul><ul><ul><li>Traffic Class </li></ul></ul><ul><ul><li>Flow Label </li></ul></ul><ul><ul><li>Routing Extension Header </li></ul></ul><ul><ul><li>Hop-By-Hop Extension Header </li></ul></ul>Further Development
    9. 9. Benefits of IPv6 <ul><li>Security </li></ul><ul><ul><li>IPSec - Security at the Network Layer is an Integral part of IPv6. </li></ul></ul><ul><ul><li>Authentication Header. </li></ul></ul><ul><ul><li>Encapsulating Security Payload Header </li></ul></ul>
    10. 10. Benefits of IPv6 <ul><li>Direct Connectivity </li></ul><ul><li>Full Peer-to-Peer functionality. </li></ul><ul><li>Multicast. </li></ul>
    11. 11. IPv6 Background Another advantage of IPv6 is The Future <ul><li>All research is taken place on IPv6. Future enhancements include: </li></ul><ul><ul><li>Autonomic Network Computing </li></ul></ul><ul><ul><li>The Internet of Things </li></ul></ul>
    12. 12. IPv6 Research Examples <ul><li>EFIPSANS </li></ul><ul><li>Project 2008-2010 </li></ul><ul><ul><li>Studies into how Autonomic Network Management can be implemented in IPv6. </li></ul></ul><ul><ul><li>Will lead to standards being set in this area. </li></ul></ul><ul><li>EU pushing for all European funded research to use IPv6. </li></ul>
    13. 13. IPv6 Research Examples <ul><li>The Internet of Things </li></ul><ul><li>Sensors </li></ul><ul><ul><li>Security </li></ul></ul><ul><ul><li>Climate </li></ul></ul><ul><li>Huge amounts of commercial and research in both of these areas. </li></ul>
    14. 14. IPv6 Research Examples Example: Keio University on their WIDE project, used in-vehicle transmitters to track 60 taxis in Yokohama to determine congestion and rainfall. Internet ITS Project tracked 1570 cars in Nagoya These two parameters are extremely relevant to their business. http://www.iepg.org/july2002/notes.html http://ir.nul.nagoya-u.ac.jp/dspace/bitstream/2237/10030/3/Journal2004_TM_NU__final.pdf
    15. 15. Converting to IPv6 Broad
    16. 16. Living in a Dual World <ul><li>Broad Strategies for IPv6 and IPv4 world </li></ul><ul><ul><li>Dual Stack – Running both IPv6 and IPv4 </li></ul></ul><ul><ul><li>Tunnelling – Hide IPv6 inside IPv4 / UDP / … </li></ul></ul><ul><ul><li>Translation – Convert IPv6 into IPv4 </li></ul></ul><ul><ul><li>Proxies – Someone speaks IPv6 on your behalf </li></ul></ul>
    17. 17. Promoters of IPv6 <ul><ul><li>IPv6 </li></ul></ul><ul><ul><li>IPv6 Task Force </li></ul></ul><ul><ul><li>European Commission </li></ul></ul><ul><ul><li>OECD </li></ul></ul>
