Abstract:
A terminal communicating with a network including a forwarding device for forwarding a packet and a control device for controlling the forwarding device in accordance with a request from the forwarding device, includes a communication unit that receives a processing rule indicating that a packet for communicating with a first destination is changed so as to communicate with a second destination, from the control device, a storage unit that stores the received processing rule, and a processing unit that in a case of communicating with the network, changes a destination of a packet in accordance with a processing rule that corresponds to the packet by referring to the processing rule stored in the storage unit.
Abstract:
A control apparatus includes: a path calculation unit that calculates first and second paths sharing start and end nodes out of a plurality of nodes; a rule generation unit that generates a first rule for forwarding a packet along the first path and a second rule for forwarding a packet along the second path; and a rule transmission unit that sends the first and the second rules to at least one of the nodes, and has at least one of the nodes forward a packet according to either the first rule or the second rule.
Abstract:
Accuracy of detection of an object existing in a reality space is improved. A detection system includes: a first detecting section (11) which detects an object with reference to a value detected by a first sensor; a second detecting section (12) which detects the object with reference to a result of previous detection of the object; an integrating section (14) which detects the object by integrating a result of detection by the first detecting section (11) and a result of detection by the second detecting section (12).
Abstract:
A communication system includes a communication apparatus configured to process a packet, and a controller configured to set the communication apparatus for processing a packet. The controller includes a memory storing instructions, and a processor configured to execute program instructions to determine a forwarding path for a packet addressed to a virtual machine based on an access rule indicating connectivity between virtual machines in accordance with an arrangement of the virtual machine, and set the communication apparatus for processing the packet.
Abstract:
A communication system includes an allocated address storage unit that stores an address allocated using host location information, and an address management unit that refers to the allocated address storage unit and uses the host location information to allocate an address to a host to which the address has not been allocated.
Abstract:
A control execution apparatus is provided with a communication unit that makes an inquiry concerning a packet processing method with respect to a predetermined control instruction apparatus, and a packet processing unit that processes packets based on an instruction from the control instruction apparatus. The control instruction apparatus is provided with a communication history management unit that manages communication history between nodes via the control execution apparatus, a node state determination unit that determines, making reference to the communication history of the communication history management unit, whether or not a node that is a transmission source or a transmission destination of the packet for which an inquiry concerning a processing method was received, is on a side that provides a service to another node, and a control instruction unit that prohibits, when at least the node is on the side that provides a service to another node, new communication from the node in question to the other node.
Abstract:
A visualization device is communicable with one or a plurality of host servers for hosting a virtual system, and includes an information acquisition unit for collecting configuration information on the virtual system and the host server, a storage unit for storing the configuration information therein, and a drawing unit for expressing a virtual machine and a virtual network configuring the virtual system with different axes based on the configuration information stored in the storage unit, expressing a connection relationship between a virtual machine and a virtual network by linking the lines extending from the respective axes, and grouping virtual machines in units of server on which the virtual machines operate thereby to generate drawing information for expressing the configuration of the virtual system and the host server.
Abstract:
A apparatus management system includes: a forwarding node(s) that supplies identification information that uniquely identifies an individual terminal to a terminal management apparatus that manages the identification information; and the terminal management apparatus that discloses the identification information about a terminal to a corresponding user, requests the user to register himself/herself as a user of the terminal from a second terminal different from the terminal, and holds associates the terminal in association with the user.
