Abstract

The invention relates to an address mapping method and an access service node. The access service node is provided with a common address mapping table, wherein the common address mapping table comprises a mapping relationship of a common identity mark and a position mark. The address mapping method comprises the following steps that the access service node receives a data message, wherein the data message comprises a target identity mark; the access service node inquires the common address mapping table according to the target identity mark in the data message; if a corresponding target position mark is inquired in the common address mapping table, the access service node forwards the data message according to the target position mark; and otherwise, the access service node is interacted with a mapping server to forward the data message. With the method and the access service node, the data flow between the access service node and the mapping server can be reduced and the data message processing efficiency can be increased.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to an address mapping method and an access service node. Background technique

[0002] The research on the next generation information network architecture is one of the most popular topics at present. At present, most studies accept that the future network will use the Internet as a unified bearer network. The Internet has maintained rapid development since its birth, and has become the most successful and vital communication network. Its flexible scalability, efficient packet switching, and powerful terminal functions are in line with the design needs of the new generation of networks. The Internet It will be the main reference blueprint for the new generation of network design.

[0003] However, the structure of the Internet is far from optimal, and there are many major design problems, among which the typical problem is the dual attribute of the IP address, that is, the ...

Examples

specific Embodiment approach 1

[0078] The following is an example of the second method of packet forwarding between the access service node and the mapping server, combined with image 3 The specific embodiment of the present invention is described, the address mapping process includes the following steps:

[0079] Step 301: The access service node receives the data message sent by the terminal user M, which contains the identity AIDm of the user M and the identity AIDn of the peer user N;

[0080] Step 302: the access service node looks up the AID-RID mapping table in the buffer, if there is an entry of AIDn, then use the found destination location identifier RIDn as the destination address of the data message, and send the data message, otherwise execute Step 303;

[0081] Step 303: the access service node searches the commonly used AID-RID mapping table, if there is an entry of AIDn, then uses the found destination location identifier RIDn as the destination address of the data message, and sends the da...
