  • Patent number: 9348847
    Abstract: A data access control apparatus has a management information table in which identification information of a storage node specified as one to which transmission of a reference request is inhibited and a reference condition are associated with each other. When a reference condition and a reference request are received, a transmission processing unit transmits the received reference condition and a reference request to storage nodes except a storage node associated with the received reference condition in the management information table. A registration processing unit determines, based on a response from each storage node to which the reference request has been transmitted, a storage node in which no data matching the received reference condition is stored, and registers identification information of the determined storage node in the management information table in association with the received reference condition.

  • Patent number: 8984522
    Abstract: A relay apparatus executes a reallocation process so as to transfer data received from an information processing apparatus allocated to the relay apparatus to a destination apparatus. The reallocation process includes the following operations. The relay apparatus determines reallocatability of the information processing apparatus on the basis of a status of receiving transfer data from the information processing apparatus. The reallocatability represents whether the information processing apparatus is reallocatable to another apparatus. The relay apparatus stores reallocatability information indicating the determined reallocatability in a storage unit. The relay apparatus determines whether to reallocate the information processing apparatus on the basis of the reallocatability information stored in the storage unit. The relay apparatus reallocates the information processing apparatus determined to be reallocated.

  • Patent number: 8892768
    Abstract: A load balancing apparatus stores a transfer rule in which a path control identifier for identifying a path for a message sent from a client device is associated with relay device information for specifying a relay device that creates the path control identifier. When receiving a message from the client device, the load balancing apparatus determines whether the message contains the path control identifier. If the load balancing apparatus determines that the path control identifier is contained, the load balancing apparatus specifies, from the transfer rule, relay device information with which the path control identifier is associated and then sends the message to a relay device that is specified by the specified relay device information. In contrast, if the load balancing apparatus determines that the path control identifier is not contained, the load balancing apparatus sends the message to the relay device specified in accordance with a predetermined condition.

  • Publication number: 20140025630
    Abstract: A data-store management apparatus includes a storage unit, a communication unit, and a processor. The storage unit holds response speed information indicating a response speed of each of data stores. The communication unit receives a subscribe request for requesting subscription of a topic updated by an update-side apparatus. The subscribe request includes communication speed information indicating a first communication speed of a first terminal that has transmitted the subscribe request. The processor identifies a first data store, among the data stores, that has a response speed higher than or equal to the first communication speed on the basis of the communication speed information included in the subscribe request and the response speed information. The processor causes the first data store to store the topic. The processor causes the first data store to respond to a read request for the topic. The read request has been transmitted from the first terminal.

  • Patent number: 8484337
    Abstract: A presence communication system capable of efficiently reducing the number of messages exchanged between presentities and watchers, thereby preventing lowering in communication quality. A presence server sets a group identifier as an identifier which is used to collectively look up a group of multiple pieces of presence information provided by presence information providers who have agreed to a use policy, aggregates and stores the presence information under the group identifier, and delivers the presence information requested to the group identifier. Each presentity provides the presence server with its presence information targeted to the group identifier. Each watcher requests the group identifier for the presence information provided by the presentities, and receives the presence information delivered from the presence server.

  • Patent number: 8266298
    Abstract: One system distributes a request for providing a service using a first communication protocol, from a terminal device to a server selected from among a plurality of servers by a server load balancer in response to the request. A corresponding relation between identification information for identifying a session generated in a distributed server and the server that has generated the session corresponding to the identification information is set in the server load balancer by the service of a second communication protocol as uniqueness assurance information for uniqueness assurance. Thus, when the provision of a service is requested using a second communication protocol by the terminal device, the server load balancer refers to the set uniqueness assurance information and selects the server for providing the service from among the plurality of servers.

  • Publication number: 20110307619
    Abstract: A relay apparatus is connected to a plurality of servers and a client to relay a message transmitted from the client to one of the plurality of servers. The relay apparatus receives from one of the plurality of servers a response to a first message transmitted from the client. The relay apparatus stores in a data storage a first server identifier of the server that has transmitted the response, in association with a first session identifier included in the response. The relay apparatus extracts, upon receiving a second message transmitted from the client, a second server identifier from the data storage on the basis of a second session identifier included in the second message. The relay apparatus determines a destination server of the second message on the basis of the extracted second server identifier. The relay apparatus transmits the second message destined to an address of the determined destination server.
