PROBLEM TO BE SOLVED: To perform restoration of a relay device, which transfers data in a network according to transfer path information, at high speed when the relay device has stopped by a failure.SOLUTION: A network control system 2 comprises a control device 50, a relay device 70, and a storage device 60. The control device 50 updates first transfer path information 500 that is stored in the control device and indicates a transfer path through which data is transferred by the relay device 70 in a communication network to be controlled; and stores the updated first transfer path information 500, as second transfer path information 600, in the storage device 60. The relay device 70, in restoration from a failure, acquires the second transfer path information 600 from the storage device 60 before replacing third transfer path information 700, which is referred to in transferring data and is stored in the relay device, with the second transfer path information 600.SELECTED DRAWING: Figure 6 |
