ABSTRACT:
A switching node in a label multiplexing type switching network includes a switch for selectively coupling input logical communications paths and output logical communications paths with each other, m permanent logical communications paths being included in the input logical communications paths where m is an integer larger than or equal to 1, n permanent logical communications paths being included in the output logical communications paths where n is an integer larger than or equal to 1. The switch node includes a call control unit for receiving connection-oriented type information through any of the input logical communications paths and for controlling the switch so that the connection-oriented type information are selectively transferred to the output logical communications paths via the switch on the basis of routing address information related to the connection-oriented type information. The switch node comprises a routing unit for receiving connectionless type information through any of the m logical communications paths and for controlling the switch so that the connectionless type information are selectively transferred to the n permanent logical communications paths via the switch on the basis of routing address information related to the connectionless type information.
