20080235507 | Encrypted Communication Method - A DNS Proxy unit (A | 09-25-2008 |
20090113073 | REMOTE ACCESS SYSTEM AND ITS IP ADDRESS ASSIGNING METHOD - An IP address assigning method for assigning a fixed address to a user terminal apparatus through a network in a system for remote accessing to the network to which a tunneling apparatus belongs from the user terminal apparatus. The user terminal apparatus connected to a first network requests a setting of a communication tunnel to the tunneling apparatus for remote accessing a second network. The tunneling apparatus receiving the request sends a DHCP message including a MAC address assigned to a physical NIC of the user terminal apparatus to a DHCP server connected to the network. The DHCP server sends a DHCP message including a fixed IP address corresponding to a preset MAC address. The tunneling apparatus assigns the IP address included in the received DHCP message to the user terminal apparatus. | 04-30-2009 |
20090180489 | NODE, ROUTING CONTROL METHOD, AND ROUTING CONTROL PROGRAM - Disclosed is a node that includes a distributed hash table generation means that generates a distributed hash table which indicates the next node to which a message is to be transferred, using a link state routing protocol, a link state information that exchange unit sends and receives link state information, and a tree delivery control unit that determines the transfer destination of the link state information so that the link state information is delivered along a tree where the source node of the link state information is a root. | 07-16-2009 |
20100054252 | System and method for external resolution of packet transfer information - When a packet transfer equipment receives a packet, it extracts several types of information contained in the received packet such as the destination IP address and the destination port number and, using the extracted information as the key, inquires of a packet transfer method resolution server about the information related to the packet transfer method. The server keeps the correspondences between several types of information contained in the packet and one or more type of information related to the packet transfer method in the database and, in response to the inquiry from the packet transfer equipment, replies one or more type of information related to the packet transfer method. The packet transfer equipment rewrites several types of information such as the destination IP address and the destination port number according to one or more type of information obtained and transfers the received packet. | 03-04-2010 |
20100191848 | INFORMATION SHARING METHOD BETWEEN NEIGHBORING NODES, NODE AND INFORMATION SHARING PROGRAM - A load caused by an information sharing message in an upper layer is reduced. | 07-29-2010 |
20100265951 | ROUTING METHOD AND NODE - A routing protocol unit ( | 10-21-2010 |
20110211535 | NETWORK COMMUNICATION SYSTEM, NODE DEVICE, ROUTING METHOD AND ROUTING PROGRAM - Each of nodes A through Z calculates delivery predictability for a destination node and exchanges the delivery predictability as an SV message with an adjacent node. At this time, the delivery predictability calculated in each of the nodes A through Z is transmitted together with a next hop node for the destination node. Upon receiving the delivery predictability for the destination node and the next hop node for the destination node, each of the nodes A through Z checks whether or not the next hop node matches the local node itself, wherein whey they match with each other, the delivery predictability is not registered with a delivery predictability database. Since the node transmitting the delivery predictability is not selected as the next hop node for the destination node, it is possible to prevent the occurrence of a routing loop between nodes. | 09-01-2011 |
20120246275 | INFORMATION SHARING SYSTEM, COMMUNICATION APPARATUS, CONTROL METHOD AND COMPUTER PROGRAM - An information sharing system is provided with multiple communication devices that wirelessly connect with other communication devices in order to communicate with them without going through an access point. Each communication device has: an internal deduction portion that, using a reception history of notification messages received from the other communication devices, deduces which information is currently being held by each of the other communication devices; a duplication determination portion that determines whether or not the information that is currently being held by another communication device and that was deduced by the internal deduction portion matches information held by its own host device; and an information exchange portion that, when the duplication determination portion determines that the information does not match, transmits a notification message that contains the information held by its own host communication device. | 09-27-2012 |
20130242934 | COMMUNICATION TERMINAL, CHANNEL SELECTION METHOD, AND PROGRAM - A communication terminal, comprises: a wireless communication unit to which a plurality of channels are allocated; a channel status calculation unit that calculates, when one of the plurality of channels is set as a forwarding channel, a capacity that can be used in the one channel by the communication terminal and a capacity that can be used in the one channel by another communication terminal; and a channel selection unit that determines, when one of the plurality of channels is set as a forwarding channel, whether a capacity that can be used in the one channel by the communication terminal satisfies a required bandwidth and determines, when another communication terminal has set the one channel as a forwarding channel, whether a capacity that can be used in the one channel by the another communication terminal satisfies the required bandwidth. | 09-19-2013 |
20130272205 | COMMUNICATION DELAY TIME DERIVATION METHOD, COMMUNICATION TERMINAL AND COMMUNICATION DELAY TIME DERIVATION PROGRAM - There is provided a communication delay time derivation method for calculating a communication delay time depending on a combination of channels set between communication terminals on a communication path in the MCH/IF environment. When selecting a channel to be used for communication in each section on the communication path per section between communication terminals on the communication path, a calculation target section specification means | 10-17-2013 |
