  • Patent number: 9608908
    Abstract: In the present situation, a switch cannot identify inner tag data (VLAN ID data before QinQed in the input of OF-NW) given to each of packets which flow in an open flow network (OF-NW). Therefore, OF-NW composed only one VLAN cannot handle a plurality of VLANs. Specifically, a controller handles a plurality of VLANs in the OF-NW in which there is only one VLAN, by mapping the inner tag data given to the packets which flow through the OF-NW, and flow cookie data showing the flow entry corresponding to the packets which flow through the OF-NW. Specifically, the flow flowing into the OF-NW is transferred from the switch to the controller, and the controller learns VLAN ID data in the input of the OF-NW, and handles the plurality of VLANs by mapping this VLAN ID and the flow cookie data showing the flow entry corresponding to the packet in the OF-NW.
