Internet Protocol version6

  1. 1. INTERNET PROTOCOL VERSION 6 (IPv6)
  2. 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. 3. KEY FEATURES •IPV6 AS A RE-ENGINEERING EFFORT AGAINST IP TECHNOLOGY •LARGER IP ADDRESS SPACE •DEPLOY MORE RECENT TECHNOLOGIES
  4. 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. 5. OBJECTIVES •CONTINUE TO PROMOTE IPV6 •FOCUS ON MOBILE IPV6, IPV6 NETWORKING,QoS •DEVELOP,TEST AND VALIDATE IPV6 •SEEK COOPERATION
  6. 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. 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. 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. 9. IPV6 HEADER
  10. 10. IPV6 AND IPV4 HEADERS IPV4 HEADER IPV6 HEADER
  11. 11. IPV6 EXTENSION HEADER •HOP- BY-HOP •ROUTING •FRAGMENT •DESTINATION OPTIONS •AUTHENTICATI ON •ESP
  12. 12. SECURITY IN IPV6 AUTHENTICATION HEADER
  13. 13. ENCAPSULATING SECURITY PAYLOAD HEADER
  14. 14. MOBILE IP
  15. 15. MOBILE IPV4 AND IPV6 •TRIANGULAR ROUTING •DEPLOYMENT PROBLEM •INGRESS FILTERING •AUTHENTICATION •ROUTER ADVERTISEMENT • SOLICITATION •ADDRESS AUTO- CONFIGURATION • NEIGHBOR DISCOVERY IPV4 IPV6
  16. 16. MOBILE IPV6 IN GPRS/WCDMA •MOBILE IPV6 FOR INTER-PLMN MOBILITY •THE BASIC OPERATION IN GPRS/WCDMA
  17. 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. 18. MIGRATION FROM 6 TO 4 NEWORK •IPV6 WITHOUT ANY GLOBAL IPV6 PREFIX •NO MANUAL CONFIGURATION FOR ISATAP
  19. 19. IPV6 TUNELLING OVER IPV4
  20. 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. 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. 22. ADVANTAGES OVER IPV4 •SCALABILITY •SECURITY •CONSIDERATION TO REALTIMENESS •PLUG AND PLAY •CLEARER SPECIFICATION AND OPTIMIZATION
  23. 23. DIFFICULTIES •INCOMPATIBILITY •INCOHERENCE •DISTRACTIONS
  24. 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. 25. QoS AND IPV6 •COMPROMISE WITH INTERNET SERVICE QUALITY •SATELLITE QUALITY TRANSMISSION AND RECEPTION
  26. 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
