摘要

PROBLEM TO BE SOLVED: To provide a communication network system and a data communication method in which a node having no fixed global address can be accessed from a client with a domain name. SOLUTION: The data communication method for the communication network system is configured to perform access from a client connected to the Internet to a node connected to a prescribed port of a gateway having an unfixed global address. On the basis of intrinsic information contained in a packet transmitted from each node, the unfixed global address of the gateway is allocated as an address of each node. COPYRIGHT: (C)2004,JPO
