  • Publication number: 20190037414
    Abstract: A mechanism related to a relay node in consideration of movement. The relay device includes: a relay unit that relays a wireless signal between a first device that is a connection destination and one or more subordinate second devices; and a control unit that assigns a network layer IP address, which has a prefix portion that is at least partially common, to each of the one or more second devices.

  • Patent number: 7746873
    Abstract: A virtual network prefix is provided as a dedicated prefix for a mobile node in a domain having a plurality of subnets. The domain includes a layered network that has a quasi-micro mobility network (QMMN) and a pure-micro mobility network (PMMN). The quasi-micro mobility network (QMMN) performs prefix-based routing, and the pure-micro mobility network (PMMN) performs routing using two different routing protocols, that is, prefix-based routing and host-based routing. In each network, processing for changing a route, such as changing cache data or the like, is performed depending on how a terminal moves.

  • Patent number: 7006449
    Abstract: An information processing device, method thereof and recording medium for communication regardless of the status of the terminal device. A domain name server stores the node identifier, and address for one or more mapping agents 121 corresponding to the host name of a terminal device. The domain name server receives a transmit request for the node identifier of terminal device 11 and the address of the mapping agent, sent from a terminal device, along with the host name or node identifier of terminal device 11. The domain name server 144 selects the node identifier for terminal device and address for mapping agent when the transmit request is received. The domain name server sends the node identifier for terminal device 11 and address for mapping agent to the terminal device.

  • Publication number: 20050108432
    Abstract: In a system-wide network of a hierarchical structure, address allocation is to be managed optimally. The system-wide network has a core portion having a static connection pertinence and a terminal portion connected dynamically to the core portion. The upper order server allocates an address block to a lower order server, whilst the lower order server returns the address block to the upper order server. The address allocation in network addition is classed into address allocation phase in the network core portion and an address allocation phase in the network terminal portion. For completing a link for outside with respect to the system-wide network, a representative server acquires its own IP address. The representative server then requests allocation of an address block used in the network terminal portion to its directly higher order server and acquires the so-requested address block. The representative server then executes automatic address allocation processing using e.g.

  • Patent number: 6895007
    Abstract: In the data transmitting method according to this invention, the application layer reads a resolver to acquire a node identifier and then makes an inquiry to the DNS server when a user designates the hose name of the destination. Upon acquiring the node identifier, the application layer transmits the node identifier to the VIP layer through the TCP/UDP layer. The VIP layer makes an inquiry to the DNS server to acquire the home prefix of the destination node in accordance with the node identifier. After acquiring the node identifier and the home prefix, the VIP layer combines them together, generating a mobile-oriented IPv6 address. Mobile permeability can thereby realized, without increasing the header size of packets, in the data transmitting method according to the present invention.

  • Publication number: 20020032794
    Abstract: There is provided an information processing device, method thereof and recording medium for evenly allotting band to both a band-guaranteed class and a non-guaranteed class. When packets are transferred from a node 1-1 to a node 1-4, a packet scheduling algorithm performs weighting of the band-guaranteed class and non-guaranteed class according to the following formula, and the calculated band is allotted to the band-guaranteed class and the non-guaranteed class.

  • Patent number: 6009528
    Abstract: A communication system includes a communication apparatus for connecting a first network to a second network, wherein a packet transmitted by a transmitting station in the first network by way of the communication apparatus to a receiving station in the second network is relayed selectively by the communication apparatus to the second network. First authentication information is created, in part, according to predetermined key information and the packet is transmitted with the header information thereof including the first authentication information. First authentication information in the header information of the packet is compared with second authentication information created, in part, according to predetermined key information, by the communication apparatus in order to determine whether or not the packet is to be relayed to the second network.
