A management server includes a processor and a storage that stores correlation information in which a category into which content is classified, location information, and an access frequency are correlated with one another. The processor acquires access information on an access from a wireless terminal to a content server via an access point and a network, a content requested by the wireless terminal, and location information corresponding to the accessed access point, updates the correlation information by rewriting the access frequency corresponding to a category to which the requested content belongs and the acquired location information, according to the access information, specifies a category and location information such that an access frequency related to the category and location information in the updated correlation information satisfies a criterion, and stores a content belonging to the category in a cache area of an access point corresponding to the location information.

Management server, content management method, and content management program for caching content in an access point

A communication device includes: processing circuitry and communication circuitry. The processing circuitry acquires first information related to one or more pieces of content cached in each of relay devices being capable of communicating with a server and are capable of exchanging any of the pieces of content cached therein with one another. The processing circuitry acquires a first content list including an identifier of each of a plurality of pieces of content stored in the server. The processing circuitry specifies, on a basis of the first information, an identifier of a piece of content cached in at least one of the relay devices among the first content list and generates a second content list including the specified identifier and second information indicating that the piece of content identified by the specified identifier is cached in at least one of the relay devices. The communication circuitry transmits the second content list.

Communication device, communication method, and non-transitory computer readable medium for content cache function

A relay device relays a signal between a first network and a second network. The relay device includes a first circuitry to wirelessly communicate with a wireless terminal over the first network and communicate with a first relay device over the second network. The relay device includes a second circuitry to detect a communication request transmitted by the wireless terminal. The relay device includes a third circuitry to decide whether relay of object information corresponding to the communication request is able to be completed with the wireless terminal while the wireless terminal stays within a wireless communication range of the relay device, and causes the first circuitry to transmit a request signal to request to relay a part or a whole of the object information to the first relay device instead of said relay device when a result of decision indicates that the relay is not able to be completed.

Relay device and communication system

According to an embodiment, a communication apparatus includes a receiving unit, an obtaining unit, and an analyzing unit. The receiving unit is configured to receive first obtaining method information, which is sent by an information processing unit to a network and which indicates a method of obtaining first data from the network. The obtaining unit is configured to, on behalf of the information processing unit, obtain the first data based on the first obtaining method information received by the receiving unit. The analyzing unit is configured to extract, from the first data obtained by the obtaining unit, second obtaining method information that indicates a method of obtaining second data which needs to be obtained along with obtaining the first data. The obtaining unit also obtains the second data based on the second obtaining method information.

Communication apparatus, communication method, and computer program product

In general, according to one embodiment, an information processing apparatus includes an issuer and a communicator. The issuer issues an offload instruction corresponding to a first process executed in company with a first identifier capable of uniquely specifying a resource of a first arithmetic operation device. The communicator transmits the offload instruction to a second arithmetic operation device and receives a result of execution of the offload instruction from the second arithmetic operation device. In the second arithmetic operation device, the first identifier contained in the offload instruction is converted into a second identifier capable of uniquely specifying a resource of the second arithmetic operation device, and processing specified by the offload instruction is executed.

Information processing apparatus and instruction offloading method

According to some embodiments, there is provided a communication device including: a processing unit and a notifying unit. The processing unit receives an acquisition request of first information from a requester and determines based on a predetermined condition whether or not the first information needs to be acquired from an acquisition destination of the first information. The notifying unit notifies a first response to the requester when the processing unit determines that the first information needs to be acquired, the first response containing an instruction of transitioning to a low power consumption status.

Processing device and method thereof

According to an embodiment, a communication apparatus controls controllable nodes. The apparatus includes an acquisition unit and a generation unit. The acquisition unit acquires at least one of a first evaluation value indicating an occurrence frequency of a control request to a target controllable node and a second evaluation value indicating an occurrence frequency of communication error at the target controllable node. The generation unit generates identification information to be assigned to control the target controllable node in a manner such that a bit length of the identification information becomes shorter as at least one of the first evaluation value and the second evaluation value increases.

Communication apparatus

A remote activating device remotely activates a device to be activated connected to a first network and a second network. The remote activating device includes a first interface connected to the first network, a second interface connected to the second network, an arrival confirmation processing unit that transmits an arrival attribute confirmation signal to the device to be activated using the first interface and confirms whether or not the arrival attribute confirmation signal has arrived at the device to be activated, and a judging unit that decides the first interface as an activation signal transmitting interface when the arrival attribute confirmation signal has arrived at the device to be activated and decides the second interface as the activation signal transmitting interface when the arrival attribute confirmation signal has not arrived at the device to be activated.

Remote activating device

According to one embodiment, a communication device includes a start-up signal reception unit that receives a start-up signal that a start node transmits for starting up a node to be started; a first interface connected to Ethernet; a second interface connected to Ethernet; a power reception unit that receives PoE power through the first interface; a PoE controller that receives the start-up signal and PoE power and gives a transmission instruction of a start-up power signal which is a PoE power signal having a signal pattern corresponding to the start-up signal; and a power transmission unit that receives the transmission instruction from the PoE controller and transmits the start-up power signal through the second interface.
