  1. INTERNET PROTOCOL VERSION 6

  2. INTRODUCTION • PROTOCOL : SET OF RULES • PRESENT PROTOCOL IPV4 • BOTTLENECKING,CONGESTION,LESS ADDRESS SPACE • IPV6 WITH INTERNET2 AND QoS • WHAT’S IPV6? • WHY IPV6? • WHY DO I NEED IPV6?

  3. KEY FEATURES • IPV6 AS A RE-ENGINEERING EFFORT AGAINST IP TECHNOLOGY • LARGER IP ADDRESS SPACE • DEPLOY MORE RECENT TECHNOLOGIES

  4. DEPLOY MORE RECENT TECHNOLOGIES • AUTO CONFIGURATION • SECURITY • FRIENDLY TO TRAFFIC ENGINEERING • MULTICAST • BETTER SUPPORT FOR AD-HOC NETWORKING • A CURE TO ROUTING TABLE GROWTH • SIMPLIFIED HEADER STRUCTURE • ALLOWS FLEXIBLE PROTOCOL EXTENSIONS • SMOOTHEN TRANSITION FROM IPV4 • FOLLOWS KEY DESIGN PRINCILES OF IPV4

  5. OBJECTIVES • CONTINUE TO PROMOTE IPV6 • FOCUS ON MOBILE IPV6, IPV6 NETWORKING,QoS • DEVELOP,TEST AND VALIDATE IPV6 • SEEK COOPERATION

  6. IPV6 ADDRESSING • 128 BITS LENGTH ADDRESS SPACING • POSSIBLE ADDRESSES 340282366920938463463374607431768211456 THREE HUNDRED FORTY UNDECILLION • IPV4 SUPPOTS 4 BILLION NODES • 64 BIT NETWORK PREFIX AND 64 BIT HOST ADDRESS

  7. NOTATION FOR IPV6 ADDRESSES • 3ffe:6a88:85a3:08d3:1319:8a2e:0370:7344 • IF 3ffe:6a88:85a3:0000:1319:8a2e:0370:7344 THEN 3ffe:6a88:85a3::1319:8a2e:0370:7344 • HERE 2001:2353:0000:0000:0000:0000:1428:57ab 2001:2353:0000:0000:0000::1428:57ab 2001:2353:0:0:0:0:1428:57ab 2001:2353:0::0:1428:57ab 2001:2353:1428:57ab ARE VALID • BUT 2001:2353::cad6 IS INVALID

  8. IPV4 ADDRESS IN IPV6 • ::ffff:192.168.89.9 IS SAME AS • ::ffff:c0a8:5909 IS NOT SAME AS • ::192.168.89.9 OR ::c0a8:5909 • 135.75.43.52 CAN BE CONVERTED TO 0000:0000:0000:0000:0000:0000:374B:2B34 OR ::374B:2B34

  9. IPV6 HEADER

  10. IPV6 AND IPV4 HEADERS IPV4 HEADER IPV6 HEADER

  11. IPV6 EXTENSION HEADER • HOP- BY-HOP • ROUTING • FRAGMENT • DESTINATION OPTIONS • AUTHENTICATION • ESP

  12. SECURITY IN IPV6 AUTHENTICATION HEADER

  13. ENCAPSULATING SECURITY PAYLOAD HEADER

  14. MOBILE IP

  15. MOBILE IPV4 AND IPV6 IPV4 IPV6 • TRIANGULAR ROUTING • DEPLOYMENT PROBLEM • INGRESS FILTERING • AUTHENTICATION • ROUTER ADVERTISEMENT • SOLICITATION • ADDRESS AUTO- CONFIGURATION • NEIGHBOR DISCOVERY

  16. MOBILE IPV6 IN GPRS/WCDMA • MOBILE IPV6 FOR INTER-PLMN MOBILITY • THE BASIC OPERATION IN GPRS/WCDMA

  17. MOBILE IPV6 IN 2G AND 3G NETWROKS • THIS REQUIRES INSTALLING A HOME AGENT • CAN BE LOCATED IN OWN OR SOME OTHER NETWORK • FEASIBLE IN OPERATORS EDGE ROUTER

  18. MIGRATION FROM 6 TO 4 NEWORK • IPV6 WITHOUT ANY GLOBAL IPV6 PREFIX • NO MANUAL CONFIGURATION FOR ISATAP

  19. IPV6 TUNELLING OVER IPV4

  20. IPV6 IN MOBILE PACKET NETWORKS • PACKET SWITCHING AIDED CAUSE NEW NETWORK IS EASILY FOUND ON FAILURE • SECURITY INCREASED ON USING GLOBALLY • 3GPP USED IN IM CN DOMAIN • THIS DOMIAN WILL PROCESS IN FUTURE 3G NEWORKS

  21. PACKET SIZE ISSUES • IPV6 REQUIRES 1280 OCTET PACKET OR GREATER • RECOMMENDED 1500 OCTET PACKET • IPV6 FRAGMENT HEADER TO SEND LARGER THAN MTU PACKET • IT IS USED FROM IPV6 TO IPV4 • TOTAL OF 1232 i.e. 1280 – 40 FOR FRAGMENT HEADER

  22. ADVANTAGES OVER IPV4 • SCALABILITY • SECURITY • CONSIDERATION TO REALTIMENESS • PLUG AND PLAY • CLEARER SPECIFICATION AND OPTIMIZATION

  23. DIFFICULTIES • INCOMPATIBILITY • INCOHERENCE • DISTRACTIONS

  24. INTERNET2 AND IPV6 • 1.1 TB OF DATA IN LESS THAN 30 MINUTES • LARGE BANDWIDTH FACILITY NEEDS LARGE ADDRESSES ALSO • HAND IN HAND DEVELOPMENT

  25. QoS AND IPV6 • COMPROMISE WITH INTERNET SERVICE QUALITY • SATELLITE QUALITY TRANSMISSION AND RECEPTION

  26. CONCLUSION • EASY CONFIG,LARGER ADDRESS BITS,QoS • BOON FOR COUNTRIES LIKE INDIA AND CHINA • NEEDS ABOUT 4 TO 5 YEARS TO COMMERCIALIZE • BOTH WILL COEXIST FOR YEARS OF TRANSITION. • FUTURE IS VERY BRIGHT
