摘要： 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.

摘要： A load distribution method is adopted by a client-server system comprising a plurality of clients 100 and a server cluster 1100, which includes a plurality of servers 800 each used for processing requests made by the clients 100 and allows the number of the servers 800 to be changed dynamically. Each of the clients 100 detects the number of servers 800 composing the server cluster 1100, sets an allocation of requests transmissible out to a newly added server 900 at a value small in comparison with that set for each of the other servers 800 right after detecting an increase in server count and then transmits out requests to the servers on the basis of the set allocation. It is thus possible to provide the clients 100 and the server-cluster system 1100 with the load distribution method suitable for a cluster reconfiguration technology for changing the number of servers composing the server-cluster system 1100 in accordance with an increase and a decrease in demand for a service.

摘要： A shared memory multiprocessor (SMP) has efficient access to a main memory included in a particular node and a management of partitions that include the nodes. In correspondence with each page of main memory included in a node, a bit stored in a register indicates if the page has been accessed from any other node. In a case where the bit is “0”, a cache coherent command to be sent to the other nodes is not transmitted. The bit is reset by software at the time of initialization and memory allocation, and it is set by hardware when the page of the main memory is accessed from any other node. In a case where the interior of an SMP is divided into partitions, the main memory of each node is divided into local and shared areas, for which respectively separate addresses can be designated. In each node, the configuration information items of the shared area and the local area are stored in registers. The command of access to the shared area is multicast to all of the nodes, whereas the command is multicast only to the nodes within the corresponding partition when the local area is accessed.

摘要： 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. After the results of fault determination in relation 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.
