摘要： In an OpenFlow network, a “proactive type” is attained and hardware (HW) performance problem is solved. Specifically, in the OpenFlow network, each of a plurality of switches executes, on a reception packet that meets a rule of an entry registered in its own flow table, an operation based on an action defined in the entry. A controller registers an entry, in which an identifier unique to a path calculated based on a physical topology of a network composed of the plurality of switches is set as a rule and an output from a predetermined output port as an action, in each of the plurality of switches before communication is started among the plurality of switches.

摘要： In a switching node, high-speed and advanced service protocol processing function is achieved by utilizing an external control server without affecting performance of conventional service protocol processing. Specifically, a forwarding engine has PCI express and an LAN interface. Depending on a type of an input packet, destination of the packet is switched to the PCI express side for conventional network service and to the LAN interface side for extended network service that cooperates with the external control server. A CPU having the PCI express and the LAN interface is provided ahead of the LAN interface. The CPU performs communication of service inquiry with the external control server at high speed via the LAN interface. After response from the control server is obtained, setting of the forwarding engine is performed through the PCI express.

摘要： In a network system in which a switch forwarding packets and a control server determining route information are separated, it is desired to achieve a redundancy of the control channel by an out-of-band control channel and an in-band control channel, when the switch receives a control message regarding the flow entry registration and the like based on the route information from the control server. Specifically, the separated switch and control server are connected by a control channel for sending and receiving the control message. The switch is not only connected to a control server via an out-of-band control channel by a route dedicated to the control message, but also connected to another control server via an in-band control channel by a route which is common with a normal data communication for determining the route information, to achieve a redundancy of the control channel.

摘要： 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.
