Abstract: Systems, methods and devices for failure analysis are provided. Using aggregation flow mining (AFM) or a similar method, an integrated mining of flow (IMF) acquires, from each router to be tested, information relating to each flow. The IMF, in relation to each of the routers, obtains distributions of statistical information such as throughput or difference for each flow; calculates, in relation to each of the distributions, a Mahalanobis distance in relation to the expected value of a reference distribution; and makes a comprehensive assessment of the distributions to perform a fault determination. When the fault determination is performed, a normal value of the distribution used for comparison is acquired from AFM and updated through feedback as needed. After the results of fault determination relating to other routers are assessed, the expected value of the standard deviation and the average value of the reference distribution used for comparison are updated.

Abstract: An information processing device includes: an information acquisition process control unit for selecting an information piece to be selected and sending an instruction to a communication unit; the communication unit for transmitting an information acquisition request to other information processing device connected via a network, and acquiring information from the other information processing device according to the instruction; and a storage unit storing a display amount information indicating the amount of display information which can be displayed on a display unit at once. The information acquisition process control unit instructs the communication unit to acquire more information than the amount indicated by the display amount information. This realizes an effective information acquisition and appropriate user-friendliness.

Abstract: Conventional network tomography techniques do not allow the location or cause of a failure to be specified, and false positives are common due to lack of information. Using aggregation flow mining (AFM) or a similar method, an IMF (102) acquires, from each router (105) to be tested, information in relation to each flow. The IMF, in relation to each of the routers, obtains distributions of statistical information such as throughput or difference for each flow; calculates, in relation to each of the distributions, a Mahalanobis distance in relation to the expected value of a reference distribution; and makes a comprehensive assessment of the distributions to perform a fault determination. When the fault determination is performed, a normal value of the distribution used for comparison is acquired from AFM and updated through feedback as needed.

Abstract: In the disclosed method for supporting the setting of a service, an allocation set that designates the allocation of a program to an information processing device is generated, the service response time and the consumed system power during use of each allocation set are calculated, and from these evaluation results, an allocation set that meets a standard service response time and reduces consumed system power is selected.

Abstract: An object of the present invention is to enhance the followability of the automatic scaling of a whole system corresponding to an increase of requests in a service linkage system for linking plural services. A cloud that executes intermediate service receives an estimate of the output of service at a previous stage by an output rate estimating unit and an information gathering response from a cloud management server, estimates an output rate, and outputs the estimate to service at a following stage. A scaling control unit receives the estimate of the output of the service at the previous stage and the information gathering response, determines resources allocated to the intermediate service, and outputs a scaling request to the cloud management server and the output rate estimating unit.

Abstract: The playback of contents in the course of progressive download is stopped depending on the information of the contents and network environments. Also, contents in the course of the playback of progressive download cannot be fast forwarded. When progressive download is indicated, a contents receiving terminal dynamically allocates resources (bus band, CPU, etc.) used in other stream processing within the receiving terminal and fast downloads a portion not downloaded to avoid the interruption of playing contents. Furthermore, the receiving terminal transmits a required communication band to a home gateway, which performs band control with other communications within a home network to allocate a maximum allocatable communication band to the contents receiving terminal.

Abstract: The present invention makes it possible to provide a reproduction resource even in an HDD recorder in which a plurality of storage processes is performed and no resource for providing the reproduction service exists. In order for realizing the above advantage, when the shortage of the reproduction resource occurs in a picture recording process, the picture recording process of the HDD recorder to which a content reproduction request is issued is switched to another HDD recorder, thereby providing the resource for content reproduction. Further, the content data stored in a dispersed manner by distributing the picture recording process is managed uniformly by recording the recording locations of the contents, which is divided and recorded, for every content data. Thus, it becomes possible to provide the content to the equipment issuing the reproduction request as a single content.

A transcoding system includes (information processing) apparatuses, such as STBs, each including a memory unit and a processing unit, and converts a coding scheme of digital contents. The memory unit stores management information acquired from different apparatuses. The management information concerns conversion functions of coding schemes of digital contents concerning the apparatuses, and is information concerning demultiplexing, decoding, encoding and multiplexing. The processing unit determines different apparatuses capable of transcoding digital contents by referring to the management information, and transfers contents data and information indicating processing contents to the different apparatuses, which includes a format conversion unit to execute transcoding according to processing contents sent from the processing unit in an apparatus.
