A data transmission method, system and access gateway

Abstract

Disclosed are a method and system for data transmission, and an access gateway. An isomerous network access gateway is configured between a network with separated identity and location and a traditional network, and a traditional network IP address is configured for a traffic server in the network with separated identity and location; a server mapping table and a client mapping table are configured in the isomerous network access gateway, and the server mapping table records the mapping relationship between the access identity (AID) and the IP address of the traffic server; the client mapping table records the relationship between the AID and the IP address of the client; and on the basis of the server mapping table and the client mapping table, the isomerous network access gateway realizes data transmission between the client in the traditional network and the traffic server in the network with separated identity and location. The present invention makes it possible for the client in a traditional network to access the traffic server in a specific network with separated identity and location by providing an isomerous network access gateway between the traditional network and the network with separated identity and location.

Description

technical field [0001] The invention relates to an identity and location separation network, in particular to a data transmission method, system and access gateway. Background technique [0002] The IP address in the TCP / IP protocol widely used in the existing Internet has dual functions, it is not only used as the position identification of the communication terminal host network interface in the network layer in the network topology, but also as the identity identification of the transport layer host network interface. At the beginning of the TCP / IP protocol design, the movement of the host was not considered. However, when the host mobile becomes more and more common, the semantic overload defect of this IP address becomes more and more obvious. When the IP address of the host changes, not only the route will change, but also the identity of the communication terminal host will change, which will lead to an increasingly heavy routing load, and the change of the host iden...

Problems solved by technology

However, as host mobility becomes more and more common, this semantic overload of IP addresses becomes increasingly apparent

When the IP address of the host changes, not only the route will change, but also the identity of the communication terminal host will change, which will lead to a heavier and heavier routing load, and the change of the host identity will lead to the interruption of applications and connections

[0003] The purpose of the separation of identity identification and location is to solve the semantic overload of IP addresses, serious routing load, security and other issues, to separate the dual functions of IP addresses, and to realize mobility, multi-homing, dynamic redistribution of IP addresses, Support for reducing routing load and mutual access between different network areas in the next generation Internet
