Network system and communication node
First Claim
1. 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.

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.
