20150280985 | DEMAND ACCOMMODATION CHANGING ORDER DETERMINATION METHOD - A processor executes the following processes. An obtainment process obtains a first number of lines, which represents a number of lines that are deleted after changing, among lines that pass through the same line route. An extraction process extracts a line for which a first demand, which is accommodated before and after changing, does not exist. The extraction process further extracts lines in descending order of a band of the first demand from among lines including first demands until a total number of extracted lines reaches the first number of lines when the number of the extracted lines is smaller than the first number of lines. Then, a fixation process fixes a first demand accommodated in a line that has not been extracted. A deletion process deletes the extracted lines. A determination process determines an order of changing line routes of demands. | 2015-10-01 |
20150280986 | MULTIFUNCTIONAL DEVICES AS VIRTUAL ACCESSORIES - At least certain embodiments of the present disclosure include a framework for turning one or more multifunctional devices coupled to a personal area network (PAN) into virtual accessories of another multifunctional device coupled to the PAN. In one embodiment, connection between a multifunctional device and a PAN is established, where the PAN is further coupled to a set of multifunctional devices. One or more distributed functionalities associated with a multi-device capable application are assigned to each multifunctional device based on relationship between the multifunctional devices. At least part of the multi-device capable application is shared between the multifunctional devices. Using the multifunctional device, the one or more distributed functionalities are performed in collaboration with the other multifunctional devices. | 2015-10-01 |
20150280987 | Multi-Tenant Information Processing System, Management Server, and Configuration Management Method - In a multi-tenant information processing system, when initially constructing a tenant, design items depending on the tenant are specified for each device constituting the tenant, and design values of the design items are calculated without overlapping with those of other tenants. In a tenant design item management table, the design items set for the devices and information indicating whether the design items depend on the tenant, are stored for each device. In a design algorithm management table, calculation formulae for making the design values to be different for each tenant are stored corresponding to the design items. A tenant design unit refers to the tenant design item management table, specifies the design items depending on the tenant among those corresponding to the devices constituting the tenant, calculates the design values of the design items according to the calculation formula, when initially constructing the tenant. | 2015-10-01 |
20150280988 | METHOD FOR AUTOMATICALLY DEPLOYING A NETWORK DEVICE CONFIGURATION - A method is disclosed for automatically configuring network devices of a data network having at least two configurable network devices, whose configuration parameters are deployable over the data network to the configurable network devices from an initial configuration state to a desired configuration state. At least one of the configurable network devices is from a first type of network devices, whose configuration requires a pre-defined series of at least one intermediate configuration state. A central deployment network device determines the actual state of each configurable network device for comparing with desired states of the configurable network devices, and in case of a difference, determines a subsequent intermediate and or respective subsequent desired configuration state wherein actual states of the configurable network devices are considered. | 2015-10-01 |
20150280989 | Built In Alternate Links Within A Switch - The network switch architecture permits modifications to the network topology in real time without the need for manual intervention. In this architecture, a switching core is capable of switching data paths directly from the ingress or egress of the switching core to alternate destination ports in real time, either under software or hardware control. | 2015-10-01 |
20150280990 | OUTDOOR DEVICE MANAGEMENT SYSTEM - Disclosed is an outdoor device management system, and a recognition device having a blank record is installed in the outdoor device and includes a first transmission module for electrically connecting a second transmission module of an electronic device such as a mobile phone or a tablet PC. When the outdoor device is installed, an identification code of the electronic device is set and provided to the outdoor device, while coordinates of the outdoor device are captured to form installation data containing the identification code, and the installation data are transmitted to the terminal device, so that the terminal device labels the outdoor device at a corresponding location of a map to complete the installation operation, and the electronic device transmits the identification code or installation data to the recognition device through the second transmission module and the first transmission module for storage and record. | 2015-10-01 |
20150280991 | METHOD AND DEVICE FOR MANAGING AND CONFIGURING FIELD DEVICES IN AN AUTOMATION INSTALLATION (I) - An exemplary method and device provide for managing and configuring field devices in an automation installation with a configuration tool designed to physically detect a field device in the automation installation, logically incorporate the field device in the automation installation, and configure the field device in the automation installation. For this purpose, the configuration tool uses a predefined field-device-specific information packet which describes the functions and data of the field device. The functions and data of the field device are displayed in an instantiated manner in windows or dialogs on a display. In order to improve clarity, the display groups windows of the same device entity for the same input context and displays them in a superordinate group window. | 2015-10-01 |
