Move The Key Issue In The Ipv6 Network

Along with the development of internet, the rich resource on internet 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 is a kind of very good solution .IPv6 fully considers 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, following the development of MIPv6, how to support the mobile Network better for MIPv6 also becomes the important development direction.In this paper, firstly we introduce the technologies about mobile IP and mobile IPv6. Based on the theories above, aim at the problem of whether the correspondent nodes should use "type 2"or "type 0" routing header when the care of address is known. To solve this new problem with the new version, I proposed to change the rules of processing "type 2" routing header, or to define a new "type 3" header especially for the nodes on mobile network.In MIPv6, as to the problem of mobile nodes being isolated because it will exercise Neighbor Unreachability Detection only after it has failed to receive from default Router Advertisement for several times, I propose an immediate application once mobile router receive any Router Advertisements with new prefix in them. Thus, the Neighbor Unreachability Detection will detect more quickly whether the mobile network has moved and so less frequently the nodes will be isolated.At the base of the research for MIPv6 supporting mobile network, at last in this paper, we set up an experimental environment, using Linux Netfilter framework to implement mobile IPv6 under RedHat 7.2 and realize the basic elements about MIPv6. In this experiment, network can keep connecting without handwork collocating network information.
