A load balancing system for performing stable processing and high reliability includes a management device which acquires time information indicating the time required in past processing on each of n processing devices, estimates a required time required for each processing devices to process processing target information based on the time information thereby obtaining an estimated time, and transmits estimated time information indicating a relationship between the estimated time and the processing device to a load balancing device. The load balancing device determines m (1
摘要:
A method in which a mail server for receiving mails manages sequence management information that records the sequence of mails stored in a data store server and the times at which a mail server sends the mails to a destination server, wherein the sequence management information is so managed as to satisfy the two conditions: one is to make not greater than a predetermined number the number of entries in any one of respective pieces of the divided sequence management information resulted by dividing the sequence management information into a plurality of pieces, each entry being included in each divided sequence management information piece and defined as a combination of key having the mail body of a certain mail as its value, and the time at which the certain mail is sent to the destination server.
摘要:
A management apparatus specifies a first communication path requirement template corresponding to a first communication path requirement of a first application module and a second communication path requirement template corresponding to a second communication path requirement of a second application module, determines the available communication module included in the first communication path requirement template to be a first communication module and determines the available communication module included in the second communication path requirement template to be a second communication module, determines an arrangement destination of the first communication module to be a first arrangement destination, and determines an arrangement destination of the second communication module to be a second arrangement destination, and sets a communication path by arranging the first application module and the first communication module in the first arrangement destination and arranging the second application module and the second communication module in the second arrangement destination.

A communication path management method has, servers that are coupled to communication devices and provide software, terminals that are coupled to the communication devices and use the software, and a network that couples the multiple communication devices, wherein the communication path management method establishes paths along which the terminals access the servers. The communication path management method comprises: a first step in which a management computer that is coupled to the network and that manages the communication devices and servers allocates, to each of a plurality of logical aggregate groups, a combination of terminals, to which the same server provides the software, and the software executed by the terminals; and a second step in which the management computer establishes communication paths of the communication devices for each of the aggregate groups.
摘要:
To reduce a load on a specific computer considering a load in association with an execution of data processing and an attribute of the data processing. A computer system executes data processing using collected data. The computer system includes a gateway configured to collect the data and a server coupled to the gateway. The data processing includes a plurality of processes. The server is configured to: manage an attribute of the data processing; monitor loads on the gateway and the server in association with the execution of the data processing; and execute process control processing whose object is reduction in the loads in association with the execution of the data processing based on the attribute of the data processing and monitoring results of the loads. The process control processing includes transfer processing configured to transfer the process and performance change processing configured to change a parameter configured to control performance of the process.
摘要:
This invention provides an apparatus that associates a location where a terminal uses communication or travel route in use of the communication, with a connection destination of the terminal. The apparatus includes a communication log analyzer that aggregates communication logs collected by network apparatuses that constitute the mobile network and analyzes it. The communication log analyzer estimates travel route of the terminal connected the network using: log information generated by a base station to be connected to the terminal at the time of starting the connection, log information generated by a base station to be connected to the terminal at the time of a handover of the connection, and log information generated by a base station connected to the terminal at the time of detaching the connection.
