Abstract: A transfer apparatus is configured to: calculate a total cost of a first route in a first network that starts from a source transfer apparatus and ends at a destination transfer apparatus; obtain a particular cost being a cost between the source transfer apparatus and a first line, which couples the source transfer apparatus and its own transfer apparatus, in a second route, which starts from the source transfer apparatus and reaches the destination transfer apparatus via its own transfer apparatus; calculate a differential between the total cost and the particular cost; set, based on the differential, a cost between its own transfer apparatus and a second line, which couples its own transfer apparatus and the destination transfer apparatus, to a value that causes the source transfer apparatus to select the second route rather than the first route; and notify the cost value to the source transfer apparatus.

Abstract: Trees employing the following two elements are used to determine communicable ranges: paths within a transmission network that are set for data transfer between adjacent communicating devices; and the adjacent communicating devices located at both ends of the paths. The adjacent communicating devices corresponding to the roots of the trees are called adjacent communicating devices located at both ends of a path that has become incommunicable due to a fault within the transmission network.

Abstract: A network management apparatus is previously registered with a physical connection relationship and positional information of a plurality of network relay apparatuses which form part of a network, as well as a configuration definition corresponding to the positional information, such that the network management apparatus can initially detect network relay apparatuses connected to the network management apparatus, and distribute a configuration definition, which takes into account a connection relationship, to the network relay apparatuses connected thereto to set the configuration definition in the network relay apparatuses in order. In this way, even if wiring is freely made, the configuration definition which should be set in each network relay apparatus can be appropriately distributed to and set in one adjacent network relay apparatus to another. Upon occurrence of a fault, the network can be appropriately recovered by a previously set recovering scheme.

Abstract: Enables control of data transmission within a network. For this, for example, a network relay apparatus makes a determination as to permission to transmit data, based on a condition relating to at least one of the transmission origin of the data and transmission destination of the data. An administration unit contains administration information indicating permission to use shared devices by users of clients. The connection relay apparatus for a target client acquires user identifying information from the target client. The administration unit acquires the user identifying information from the connection relay apparatus for a target client, and referring to the administration information, detects a target shared device that is one of the shared device permission to use of which has been granted to a user of the target client.

Abstract: A network management apparatus is for managing a plurality of switching devices that relay data through a data communication network. The network management apparatus includes a configuration information storage, a connectivity relationship detector and a configuration information modifier. The configuration information storage stores first configuration information. The first configuration information is configured in the switching devices and includes information to be determined in accordance with connectivity relationships among the switching devices. The connectivity relationship detector detects changes of connectivity relationships among the switching devices. The configuration information modifier dynamically modifies the first configuration information in accordance with detected changes of connectivity relationships.

Abstract: A handling address range is pre-assigned to each of switching devices consisting a network switching system. The switching device has a data receiving unit, an assigned data transport unit, an unassigned data transport unit, and a lower transport layer transport unit. The data receiving unit receives data including a destination address in a network layer and a destination identifier in a lower transport layer. If the destination identifier specifies the device itself, the assigned data transport unit and the unassigned data transport unit perform data transfer, whereas if the destination identifier specifies a device other than itself, the lower transport layer transport unit performs data transport. When the destination address is assigned address, the assigned data transport unit generates data including an identifier of a device corresponding to the destination address, and transports the generated data.

Abstract: A switching node (MGS) 1 connected to a relay network 5 has a table 37 prestoring bandwidth control parameter values in correspondence with the size of data transferred via the relay network. When a request for accessing a remote storage apparatus is received, the switching node obtains the bandwidth control parameter values adapted to the transfer data size indicated by the access request are obtained from the table 37, and automatically sets a path having an optimum bandwidth on the relay network by using the parameter values. The path is automatically released when the data transfer is finished.
