Tunnel based mobile IPv6 quick switching method

Abstract

This invention provides a quick switching method based on tunnel IPv6 for the switch in mobile node moved from old access router to the new, which contains 1, the new accessed router setting a new transaction address to mobile node, 2, establishing a bidirection tunnel between mobile node and old accessed router, whose two ends addresses are respectively new transaction address mobile node and IPv6 address of old accessed router, said invention speeds up switching and reduces switch time delay.

Description

technical field

[0001] The invention relates to the field of computer networks, and more specifically relates to a tunnel-based fast switching method in mobile IPv6. Background technique

[0002] With the rapid development of wireless communication technology and network technology, people are no longer satisfied with only accessing the Internet at a fixed location, but expect a ubiquitous access method. Mobile IPv6 is a mobility solution proposed by the IETF, which can ensure that the transport layer connection of the terminal is not interrupted during the mobile process.

[0003] The following are relevant technical terms:

[0004] 1. Mobile Node (MN): A mobile host that can switch from one link to another without interrupting the current connection. In this paper, the mobile node supports the mobile IPv6 protocol.

[0005] 2. Corresponding node (CN): It is a fixed / mobile host that communicates with the mobile node, which may be referred to as the corresponding node. ...
