Study And Implementation Of IPv6-based Mobile Internet

Along with Internet develop fast, the rich resource on net produces huge attraction. Receive into Internet, visit Internet to become the present Information demand with the most urgent field, but this gets a lot of restrictions of IP address, New IPv6 a kind of very good solution. IPv6 when design fully considered the motion demand, and will mobile IPv6 takes IPv6 the basic constituent, Therefore IPv6 may even better support end-to-end as well as the multimedia service under the motion environment. Along with the IPv6 standard maturity, in the mobile network gradually introduces IPv6 also becomes the correspondence network the important development direction.This paper is the research in-depth, IPv4 network is to IPv6 network transitional problem and the technology that more some kinds of more present comparisons ripen:two protocol warehouse technical tunnel technology and a network address translation — protocol translation technology by analyzing of the structure characters of IPv6 protocols; the safe protocol of having analysed IPv6 in detail—the safe ability of IPSec, the security system of IPSec form , IPSec as well as the working way of IPSec are in IPv4 the realization in IPv6 way; have discussed the integrity of IPSec in IP message, secretance, data source certification and the ability of fighting the aspects such as rebroadcast; article research mobile IPv6 the work mechanism and mobile IPv6 the essential technology in detail, further proposed one kind attacked the event based on the IPv6 loophole the characteristic and the behavior invasion technology unifies guarantees the network security the solution and based on the IPv6 (mobile IPv6) mobile internet design and the realization plan.Article is divided into 9 parts. The first part is article background and meaning as well as domestic and international research present situation; Second part has analysed IPv6 and mobile internet in detail; 3th part is related technical research of IPv6 in mobile internet; 4th part has analysed the technical principle of IPSec; 5th part is behavior research and the feature based on IPv6 leak attack incident; 6th part is technical research of mobile IPv6; 7th part is realization and the design based on mobile internet of IPv6 (mobile IPv6); 8th part is network emulation and data analysis; Finally, research work of the article is summarized and further research content is subjected and the development of the future is predicted.
