ATM COMMUNICATION NETWORK SYSTEM AND ATM COMMUNICATION EQUIPMENT

摘要

PURPOSE: To reduce information quantity on a connection control table in an ATM exchange and to process the reception processing of an ATM terminal equipment at high speed with a hardware processing in an ATM communication network system. CONSTITUTION: In the ATM communication network system, a pair of inter- multiple point connections 6a of a virtual path are set between the ATM communication equipments (ATM terminal equipments 1) and virtual channel identifiers are uniquely assigned to the respective ATM communication equipment. The ATM communication equipments store and transmit the virtual channel identifier assigned to the transmission destination ATM communication equipment into/to the header of an ATM cell. The transmission destination ATM communication equipment judges whether information is addressed to oneself or not by the virtual channel identifier of a received ATM cell. When it is addressed to oneself, the received ATM cell is fetched in side. When it is addressed to others, the received ATM cell is aborted.
