ABSTRACT:
For executing a signaling operation of a virtual channel which is used for communication between a transmission side and a reception terminal in a connection-oriented packet network, the transmission side acquires source routing information relating to a source route path between the transmission side and the reception terminal. The transmission side includes a transmission terminal and a switch between the transmission terminal and the reception terminal. With reference to the source routing information, the transmission terminal carries out a signaling operation of a setup for the virtual channel. It is preferable that the switch acquires the source routing information to transmit the source routing information to the transmission terminal. Alternatively, the transmission terminal may acquire the source routing information.
