Problems solved by technology

[0011]1. A large number of Tunnel Brokers need to be deployed, and the networking cost is too high
[0012]2. It must rely on the existing Tunnel Broker technology, and the application prospect of this technology is not clear
[0016] The disadvantage of the above scheme is: this scheme cannot solve the problem of mobile IP
In addition, the NAT / PT method needs to modify the packet header, which will cause many problems

Embodiment Construction

[0061] Describe the present invention in detail below in conjunction with accompanying drawing, the device described in this method comprises FHA, the structural representation of its embodiment is as follows figure 1 shown.

[0062] FHA: Support both MIp4 and MIp6 protocols. Save the mapping relationship between the MN's IPv4 COA and THOA, assign THOA to the MN according to the mapping relationship; accept the MN's registration and save the registration information, when the MN's registration expires, the FHA will delete the above-mentioned saved MN's Mapping relationship and registration information. Acting as the HA of the MN in the IPv4 network, it encapsulates the IPv6 data packet sent by the CN or HA to the MN into an IPv4 data packet, and decapsulates the IPv4 data packet sent by the MN to the CN or HA. FHA includes: a registration management module and a routing management module. The FHA is set in the boundary range between the IPv6 network and the IPv4 network or...

Abstract

The invention provides devices and method to actualize the nodes roam in network on the Internet Protocol version four, the devices mainly comprises: FHA (exotic home agent). The methods comprises: MN(mobile node) obtain the THOA (temporary IPv4 addresses) distributed by FHA, register its IPv4 addresses to the FHA; the said FHA according to distributed THOA to MN and MN registered IPv4 addressesinformation, transmit data packet between the MN and the CN (communications nodes) or HA (home agent). Using the methods described in this invention can achieve the routing program that dual stack mobile node roam to IPv4 network from IPv6 network.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a device and a method for realizing node roaming in the Internet protocol version 4 network. Background technique [0002] In the existing TCP (Transmission Control Protocol) / IP (Internet Protocol) framework, the IP address of the MN (Mobile Node) represents the location of the MN. The network you are on determines the routing. When the MN moves from its home network to a foreign network, the data packets sent from the CN to the MN will still be routed to the MN's home network. Since the MN is not in the home network at this time, the data packet will be discarded in the home network of the MN, and the communication between the MN and the CN will be interrupted. [0003] With the development of mobile communication technology, the future mobile network must be based on IP, and the MN is required to keep the existing communication uninterrupted when roaming or nomadic from t...
