Abstract: There is a need for applying an appropriate QoS setting to a complex information platform apparatus capable of flexibly changing an apparatus configuration so as to ensure an intra-apparatus communication band and realize management communication independence. Multiple processing modules are combined to construct one or more processing units with different apparatus types. An apparatus template management table prepares multiple levels of setting specifications with different ensured bands for intra-apparatus communication corresponding to each apparatus type. One set of setting specification is selected from multiple levels of setting specifications prepared for an apparatus type settled at the time of configuration setting. A QoS setting management table is generated based on the selected setting specification. When the configuration is set or changed, setting verification means verifies whether or not a total of ensured bands associated with each adapter is within an allowable range.
