Therefore, for registration, rewriting and deletion of the entry of the forwarding table which are performed on the communication device 102 by the control server 101; the communication device 102 verifies contents of control instructions from the control server 101; the communication device 102 holds the result of this verification; the control server 101 acquires the result of the verification; the control server 101 judges whether or not a series of controls can be executed based on the results of the verification from the plurality of communication devices 102; and then the control server 101 invokes the execution at the plurality of communication devices 102. |
