METHOD AND SYSTEM FOR IMPLEMENTING INTERCONNECTION BETWEEN INTERNET PROTOCOL VERSION 4 NETWORK AND NEW NETWORK

摘要

The present invention provides a method and system for implementing intercommunication between an Internet Protocol Version 4 (IPV4) network and a new network. The new network adopts an addressing format different from that of the IPV4 network. The method includes a step of an IPV4 network host sending a message to a new network host and a step of the new network host sending a message to the IPV4 network host. The system includes an IPV4 network host, an intercommunication functional unit and a new network host. The present invention also provides a method for implementing intercommunication between a first network and a second network. By adopting the mode of IPV4 address multiplexing, in the present invention, a compatible format address is distributed to the new network host for intercommunicating with the IPV4 network. The compatible format address includes an IPV4 format address and a port number, and the IPV4 address may be routed in the IPV4 network, thereby achieving intercommunication and simultaneously resolving the problem of lack of the IPV4 address. Additionally, compatibility with the original IPV4 application program in the new network host can be achieved as long as the protocol stack of the new network host is upgraded.
