Abstract: It is determined whether or not the address of a first type specified in an address resolution query is an address that allows direct routing to a first network. If the direct routing is determined to be allowed, a routing table is configured such that a packet including, as a destination, the address of a second type obtained by the address resolution query is forwarded to the first network. If the direct routing is determined not to be allowed, the routing table is configured such that a packet including the obtained address of the second type as a destination is forwarded to a second network.

Abstract: A communication method is used in a relay device that is provided between a terminal and a server. The communication method includes: verifying a reliability of a server certificate that is transmitted from the server for cryptographic communication between the server and the relay device using a processor; issuing a proxy certificate based on the reliability of the server certificate for cryptographic communication between the relay device and the terminal using the processor; and transmitting the proxy certificate to the terminal.

Abstract: An access control method for a network including a plurality of packet communication apparatuses is disclosed. The access control method includes a first step in which a sender packet communication apparatus attaches user attribute information to a packet to be transmitted, and a second step in which a communication control mechanism within an end system corresponding to a destination packet communication apparatus or a packet receiving apparatus performs access control based on the user attribute information attached to the packet.

Abstract: A massage machine equipped with air cells (23a, 23b) disposed opposite to each other at a given distance therebetween in the up-down direction, a pair of support plates (22, 22) for supporting the air cells (23a, 23b) from the outside in the up-down direction, a pair of rotation portions (21) for applying a drive force to the pair of support plates (22, 22) in the front-rear direction and for supporting the support plates (22, 22) on both the left and right sides, guide portions (25) formed in the pair of rotation portions (21) to support the pair of support plates (22) so that the pair of support plates is movable in a direction in which the support plates (22) approach and separate from each other, biasing portions (26) for biasing the pair of support plates (22) in a direction in which the support plates approach each other, and a drive unit (28) for applying a rotation drive force to the rotation portions (21).

Abstract: In an access management method in a network including at least one end system, a packet communication unit for routing, and an access management server including an authentication function, a communication partner is authenticated for each session and a communication permitted by a communication partner is permitted by the access management server. A packet meeting a condition of a denied packet being denied by the communication partner is discarded by the packet communication unit.

Abstract: A relay apparatus for relaying communications between information processing units in a network includes: an address check unit for checking for an overlap of an address allocated to each of a plurality of information processing units existing in a network; an address conversion unit for converting an overlapped address detected by the address check unit to thereby create a post-conversion address; and a relay processing unit for relaying communications between the information processing units on the basis of the post-conversion address.

Abstract: There is provided a network system having high security nature and excellent operability. The network system has an information provision system provided with an information provision server which provides information and a first network, an authentication system provided with an authentication server which authenticates access to the information provision server by a user using a user terminal, and a communication channel.

A packet meeting a condition of a denied packet being denied by the communication partner is discarded by the packet communication unit.

Abstract: To provide a load sharing system using a virtual router facilitating dynamic load distribution. The load sharing system includes a plurality of equipment units each functioning as a router which constitutes a virtual router having a single common address; and end systems being connected to the network through the virtual router. Among the plurality of routers constituting the virtual router, one equipment unit functioning as a router is assigned as a master router, while the other equipment unit(s) is assigned as a backup router. The master router dynamically allocates packet condition for defining the routing object to each router, then to advertise to the backup router. Routing processing between the network and the end system is performed by the plurality of routers each having a routing function.

Abstract: In a band control device having a trunking function used in an end apparatus, a relaying apparatus, and the like, a distributor distributes a traffic to a sub-logical link into which specified ones of the physical links in the logical link are aggregated so as to meet a specified condition of the traffic. Also, the physical links of a number corresponding to the traffic amount is assigned to the sub-logical link. A controller transmits/receives a message for establishing the sub-logical link to/from an opposite controller, and further relays the message to the subsequent apparatus.
