Publication number: 20150215394Abstract: 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.Type: ApplicationFiled: August 6, 2013Publication date: July 30, 2015Inventors: Naokazu Nemoto, Yasuhiro Takahashi, Kansuke Kuroyanagi, Kunihiko Toumura
