A transport system comprises a transport apparatus, which is used to construct a transport network using MPLS-TP; and a control apparatus for establishing a path in the transport network. The transport apparatus is coupled to a transfer apparatus, which is used to construct a transfer network using a network protocol different from an MPLS-TP protocol and uses the network protocol to establish a path in the transfer network in an autonomous distributed manner. The control apparatus and the transfer apparatus use the network protocol of the transfer network to transmit/receive, via the transport apparatus, control messages for controlling the transfer network. The transport apparatus avoids notifying the transfer apparatus of the fact that the control apparatus is not in a normal state, in a case where the path established in the transport network is determined as the normal state, even the control apparatus is determined as the abnormal state.
