20090185561 | PACKET FORWARDING DEVICE AND FORWARDING METHOD - A packet forwarding device that maintains packet sequence before and after packet forwarding is provided. A cache stores forwarding information. A forwarding unit refers to the forwarding information to attempt to determine a forwarding destination of a received packet, sends the packet to a control unit irrespective of whether or not the forwarding destination of the packet could be determined, and in cases in which the forwarding destination of the packet could not be determined, requests the control unit to determine the forwarding destination of the packet. The control unit receives the packet from the forwarding unit, and in cases in which the control unit has been requested by the forwarding unit to determine the forwarding destination of the packet, determines the forwarding destination of the packet, sends the packet to the forwarding destination and stores the forwarding destination as forwarding information in the cache, and in other cases, sends the packet to the forwarding destination determined by the forwarding unit. | 07-23-2009 |
20090232130 | GATEWAY ROUTER AND PRIORITY CONTROL FOR EMERGENCY CALL IN IP TELEPHONY SYSTEM - A gateway router in an IP telephony system includes a determination section which determines whether or not an arriving session control signal is of an emergency call, and a controller which dynamically assigns to emergency calls and other general calls a predetermined number of sessions that can be simultaneously connected and thereby performs control such that connection processing is carried out preferentially for a session control signal of an emergency call. | 09-17-2009 |

20130077481 | NETWORK SYSTEM AND NETWORK REDUNDANCY METHOD - 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. | 03-28-2013 |

20130086295 | COMMUNICATION CONTROL SYSTEM, SWITCHING NODE, COMMUNICATION CONTROL METHOD AND COMMUNICATION CONTROL PROGRAM - 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. | 04-04-2013 |
