A communication network capable of establishing an SVC bypass route when a failure occurs in a PVC multiplexed line wherein each of ATM switches at both ends of a PVC stores the relations of SVC specifying information and the other party PVC information in association with each PVC in a management table. At the time of bypassing, one of the switches transmits a message including the other party PVC information to another ATM switch for each PVC to be bypassed and another ATM switch specifies a PVC to be switched on the basis of the received message and switches the PVC to an SVC specified by the corresponding SVC specifying information stored in the management table.
