Dynamic ATM address mapping system and dynamic address mapping method in OSI communication environment via ATM-SVC network

摘要

A dynamic ATM address mapping system in an OSI communication environment via an ATM-SVC network, wherein an ATM address server for registering and controlling address information of pair of ATM address and network address on each end system and relay system of a logical sub-network is provided within the logical sub-network, each of the end system and relay system within the logical sub-network comprising address information registration requesting unit for requesting the ATM address server to register the address information of the own ATM address and network address in pair, and address acquiring unit for receiving an ATM address of a communication party from the ATM address server and registering the ATM address, the ATM address server comprising address registering unit for registering the address information of the ATM address and network address in pair, upon receipt of the address information registration request from the end system and relay system, and address notifying unit for notifying an ATM address of a communication party required by the end system and relay system, to the end system and relay system.
