Embodiment Construction

[0024] Fig. 2 shows the embodiment of the present invention in the access management entity of the flexible IP network technology system. In the figure: the basic domain management entity is the identity of the proxy mobile node, and completes data forwarding; the extended domain management entity (or mobile node) is the initiator or receiver of data transmission; the access management entity is responsible for accessing the request of the mobile node, Fast forwarding of data is completed; the basic network domain NAT is responsible for completing the address translation of the basic network domain private address; the extended network domain NAT is responsible for completing the address translation of the extended network domain private address. Both the basic domain management entity and the extended domain management entity (or mobile node) are the end points of the final tunnel, which can complete double-layer encapsulation of data. The specific method is as follows:

Abstract

This invention relates to IP tunnel method for data intermediate trasition in flexible IP network technology. Firstly an access management entity sets up a data port, the basic domain management entity and expanding domain management entity are connected with the port then to exchange data connection information. The basic or the expanding set up a two-layer tunnel, namely, the package of tunnel end includes an outer package packet head for the first step transmission and an inner package packet head for the second step direct route, finally, the access sets up an one-layer tunnel based on IP, an all-round.

Description

Technical field: [0001] The present invention belongs to the IP network technology, especially the IP tunnel technology in the flexible IP network technology system, and specifically relates to an IP tunnel technology for how the access management entity in the flexible IP network technology system quickly forwards data. The flexible IP network technology system mentioned in the present invention refers to the basic domain management entity, the extended domain management entity, the access management entity, and the mobile node. Nodes can achieve interactive access to their basic network domain at any time. Background technique: [0002] In the mobile IP technology that solves similar problems with the flexible IP network technology system, IP tunneling technology is used to encapsulate an IP-based data packet as the payload of another IP data packet and then transmit it. The path through which the data is transmitted is called a tunnel. [0003] At present, many services ...
