- the same processing is performed in the switch 10-2, and the packet transmitted from the server 30 is transferred to the client 40 via the switch 10-2.
- the controller 20 that has received the control message Packet-in (transferred) recognizes that it is not a normal packet-in but a packet-in (transferred), and starts calculating routes and creating a flow entry. However, the packet output instruction (Packet-out) using the packet or packet information included in the Packet-in (transferred) is not performed (S005 in FIG. 6).
- the packet order reversal and the packet loss are effectively suppressed.
- the reason for this is that only the packet entry (forwarded) is sent to the controller by flooding and the packet transmission instruction from the controller via the control plane by the previously set flow entry for Unknown Unicast. This is because the packet output processing is configured to be suppressed.

- the transmission of the control message Packet-in (transferred) for the second and subsequent periods after the transmission of the first control message Packet-in (transferred) has been described as being suppressed.
- the predetermined period the number of receptions of the packet that is the target of the control message Packet-in (transferred), the amount of data, or the like may be used.
- the switch 10 suppresses the control message Packet-in (transferred) until the number of received packets and the amount of data exceed a predetermined threshold.
- the switch 10 resets these values and transmits a control message Packet-in (transferred).
- the number of packet receptions and the amount of data can be implemented by providing a flow statistical information field (Counter) in the same way as the flow entries described in Non-Patent Documents 1 and 2.
- the present invention is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments may be made without departing from the basic technical idea of the present invention. Can be added.
- it is suitable not only for data center applications but also for image distribution services and TV phone services that are greatly affected by sequence control and packet loss. Applicable.
- the controller 20 has been described as controlling the switch 10, but the above-described flow entry is held, and from the received packet and the installed application according to the content thereof.
