ATM communication network system with common system information storage

摘要

In an ATM communication network system comprising plural ATM terminals 1a to if respectively having individual real memories 38a to 38f to transmit and receive ATM cells and ATM switching apparatus 2a, 2c and 2e for switching the ATM cells transmitted and received among the ATM terminals 1a to if and setting a broadcast connection 4a designating the respective ATM terminals 1a to if as the transmitting ATM terminals, the virtual memory 3 may be realized on the real memories 38a to 38f of the ATM terminals 1a to if by periodically performing the broadcast cell communications using the broadcast connection 4a designating all the ATM terminals 1a to if in the present system as the transmitting apparatuses.
