This document discusses Internet Protocol Version 6 (IPv6), including its key features, objectives, addressing scheme, headers, security, and relationship to IPv4. IPv6 was developed as a replacement for IPv4 due to IPv4's limited address space and other constraints. IPv6 features a much larger 128-bit address space to allow for continued growth of the Internet, as well as improvements to security, extensibility, and mobility support. The transition from IPv4 to IPv6 will take several years as both protocols coexist during migration.

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
