Load control system for controlling a plurality of processes and exchange system having load control system

摘要

In a load control system having n types of processes provided for processing requests of an identical type, a load processing unit executes one of m types of processes among the n types of processes in response to one of the processing requests where n and m are respectively integers equal to or larger than 1 and m is equal to or smaller than n. A monitor unit periodically monitors a load of the load processing unit and selects the m types of processes from among the n types of processes on the basis of the load of the load processing unit. An execution ratio calculation unit determines execution ratios of the m types of processes so that the load of the load processing unit is equal to or lower than a first reference value and an execution ratio of at least one of the types of processes is equal to or higher than a second reference value. The load processing unit executes the m types of processes in response to the processing requests with the execution ratios of the m types of processes.
