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： On the OpenFlow network/normal network boundary, the route cannot be appropriately changed under a communication trouble with the controller. In this invention, the controller makes the route formed by internal switches optimal by updating the Flow table of each internal switch. Among internal switches, the internal switch A forms the optimal route with an external switch to become an active internal switch. The internal switch B forms a redundant route with the external switch to become a standby internal switch. When inability of the connection between the controller and the internal switch A is detected, the internal switch A performs a link-down of the port for connecting to the external switch. When the link-down of the port connecting to the internal switch A is detected, the external switch changes the route so that the traffic to the active internal switch A is transferred to the standby switch B.

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.
