Problems solved by technology

[0006] The purpose of the present invention is to provide a method for implementing the self-adaptive extended domain management entity mechanism in the flexible IP network technology system, which solves the problem that the traditional mobile IP foreign agent entity in the background technology performs the function of full agent, resulting in two original normal The communication efficiency of the communicating foreign host is reduced or even interrupted, and the technical problem of occupying the system resources of the foreign agent entity

Embodiment Construction

[0033] The flexible IP network technology system of the present invention refers to a system composed of a basic domain management entity 1, an extended domain management entity 3, and an access management entity 2, which enables the mobile node 5 to communicate normally using the original IP address in the extended network domain link system.

[0034] The invention utilizes the original socket and proxy ARP technology to realize the successful registration of the mobile node and the correct proxy of the mobile node by the extended domain management entity 3 when the mobile node roams in different network segments. That is, after the mobile node 5 roams across the Internet, the mobile node 5 sends a registration request to its extended domain management entity 3, and the mobile node 5 can register normally. After the registration is successful, the extended domain management entity 3 can correctly respond to the mobile node 5 ARP requests.

Abstract

A method for realizing adaptive expand domain management entity system in a flexible IP network technology system is that when a network acc point of the mobile node is switched to another link, the address of the expand domain management entity is got by its agent to judge if they are in the same segment, if so, it sets up the registration of requesting data packet according to the traditional mobile theory to send it to the expand domain management entity to forward the registration request, if not, related information is got to make up of original SK and delivers registration request. The mobile node registers and tells its forward address to the basic domain entity, a two-way tunnel is built between them: The expand entity generates an agent ARP list of a mobile node to user the agent ARP system for successive mobile nodes.

Description

technical field [0001] The invention relates to a method for performing data communication after a mobile node roams to an extended network domain in a flexible IP network technology system. That is, it relates to a method in which the mobile node communicates with the extended domain management entity and the extended domain management entity acts as a proxy for the mobile node when the mobile node roams to a network different from its own network address. It specifically relates to a method for realizing an adaptive extended domain management entity mechanism in a flexible IP network technology system. Background technique [0002] With the development of computer networks and the improvement of the size, weight and performance of portable tools such as notebook computers and PDAs, the realization of mobile office has gradually become easier. Mobile IP technology is a technology derived from a series of standards developed by IETF to expand the mobility of IP networks. It...
