  • Publication number: 20150215394
    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.

  • Patent number: 9071612
    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.
