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.

Abstract: To equalize loads of a hierarchy-type network system, the loads at the lower levels of the system are taken into account. In an arbitrary 3-level hierarchy (n to n+2 levels), a node of the n+1 level obtains, from each of one or more nodes of the n+2 level, load information thereof, calculates the spare resource-amount thereof on the basis of the obtained load information and load information thereof, and transmits the calculated spare resource-amount thereof to a node of the n level. The node of the n level calculates weighting values on the basis of the spare resource-amounts obtained from each of the nodes of the n+1 level, and distributes a received processing request to either one of the nodes of the n+1 level on the basis of the calculated weighting values.

Abstract: In a system with a terminal sending a request, when a load distributing unit distributes the request to many service providing apparatuses, the load distributing unit becomes a bottleneck of performance and/or a single point of failure. When the load is distributed to the service providing apparatuses without using the load distributing unit, a particular function is required on the terminal side to appropriately select one of apparatuses. A name resolution unit including an address group management table with IP addresses to select, for a request from a terminal, an address from the table to return the address to the terminal and a plurality of service providing apparatuses to which at least zero IP address selected from the table is allocated without duplication are arranged such that each service providing apparatus is allocated with IP addresses according to processing performance thereof, thereby conducting appropriate load distribution.

Abstract: A vehicle-onboard apparatus system, comprises a portable terminal and a vehicle-onboard machine that are configured to be coupled to each other for communication. The portable terminal and the vehicle-onboard machine each store operation logs including operation contents thereof. When an operation of the vehicle-onboard machine and an operation of the portable terminal relate to each other, an operation log resulting from the operation of the vehicle-onboard machine and an operation log resulting from the operation of the portable terminal are associated with each other by first identification information. The vehicle-onboard machine makes a user to recognize the first identification information corresponding to an operation causing detected predetermined state. When the portable terminal receives an input of the first identification information presented by the vehicle-onboard machine, the portable terminal acquires the operation log associated with the input first identification information.
