Abstract
An ATM network system which connects a source terminal equipment to a destination terminal equipment by an SVC through a plurality of ATM communication nodes. In the source ATM communication node, a priority level definition table is preset with priority levels for the SVC whose service category is the UBR service per a physical port, MAC address, or IP address, a control unit transmits a SETUP message including the priority levels, a switch controller controls a readout level of a user's information cell based on the priority levels. In each of the ATM communication nodes having received the SETUP message, the switch controller controls a readout level of the user's information cell based on the priority levels included in the SETUP message.

A network system, which connects a source terminal equipment to a destination terminal equipment by a connection, comprising:
- a first communication node;
- adjacent to the source terminal equipment, including a priority level definition table in which priority levels for the connection whose service category is a predetermined service are preset per a physical port, a control unit which transmits a control message including the priority levels when the connection is set up, and a switch controller for controlling a readout level of a user's information cell based on the priority levels;
- second communication nodes, between the first communication node and the destination terminal equipment, including a switch controller which controls a readout level of the user's information cell of the connection based on the priority levels included in the control message as received.
A communication node comprising:
- when provided adjacent to a source terminal equipment;
- a priority level definition table, set per MAC address, in which priority levels for the connection whose service category is a predetermined service are preset per MAC address;
- a control unit which transmits a control message including the priority levels when a connection is set up;
- a switch controller for controlling a readout level of a user's information cell based on the priority levels;
- and
- a multi-layer processing portion used in a MAC address.

A communication method comprising:
- adjacent to a source terminal equipment;
- presetting priority levels for a connection whose service category is a predetermined service, per a physical port;
- transmitting a control message including the priority levels when a connection is set up;
- and
- controlling a readout level of a user's information cell based on the priority levels;
- and
- between a communication node and a destination terminal equipment, controlling a readout level of the user's information cell of the connection based on the priority levels included in the control message as received.
