摘要： In an OpenFlow network, it is determined which port of which node device a terminal connected to a group of node devices is connected to, by only using the source MAC address and port number of a packet transmitted from the terminal. Specifically, the node device compares a set of the port number and source MAC address information of a packet transmitted from the terminal to the node device with a set(s) of a port number and MAC address information held in a preliminary search table to check whether they match each other. When the comparison does not result in a match, the node device notifies the controller by using the inquiry information (packet-in) function of OpenFlow. Furthermore, the node device compares the destination MAC address information of the packet with a set(s) of MAC address information held in a final search table to check whether they match each other.

摘要： A controller completes the setting of a flow entry to a switch previously before the communication of a virtual machine starts. Specifically, the controller sets information of the virtual machine and information of a server on which the virtual machine operates. The controller detects the information of the server under the switch through the switch. When the set server information and the detected server information match to each other, the controller sets a flow entry for a packet destined to the virtual machine to the switch based on information of the virtual machine on the server. After that, the virtual machine starts communication.

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： A communication apparatus is provided with: a processing rule storage unit capable of storing a first processing rule for unknown packets set in advance, and a second processing rule set by a control apparatus; a packet processor that processes received packets based on processing rules stored in the processing rule storage unit; and a state notification unit that transmits a predetermined control message to the control apparatus when a packet is processed using the first processing rule. On receiving the predetermined control message, the control apparatus creates the second processing rule to be set in the communication apparatus and sets the second processing rule in the communication apparatus, and also discards packets included in the control message. The communication apparatus continues packet processing using the first processing rule until the second processing rule is set by the control apparatus.

摘要： In an open flow system, it is made possible to confirm a flow having succeeded or failed in the registration on a flow table. Specifically, a controller transmits and receives an open flow message to and from a switch. The switch is provided with a flow table which manages flows registered from a controller, and a flow table reading section which reads corresponding data, a flow table control section which performs processing of addition, deletion and modification of a flow entry, and a platform function managing section which determine whether an object flow entry is valid or invalid according to an inquiry from the flow table control section. The flow table has a normal flow table and a save flow table. A valid flow entry which conforms to configuration data of the switch is registered on the normal flow table. An invalid flow entry which does not conform to the configuration data of the switch is registered on the save flow table.
