Abstract
A method of scheduling jobs to be executed by a resource in a computer system wherein the jobs are grouped in “classes.” The job classes vying for the resource's attention are arranged in a hierarchy. Each job class has a time-function value that controls when the job class is selected by the resource if processing time becomes available. Within a particular level of the hierarchy, scheduling priorities are defined by one or more time-based functions, each of which may be constant or dynamically varying. When constant time-based functions are used, each job class has a schedule value that remains fixed with time. When dynamic time-based functions are used, job class “time-function values” are modified to alter the timing by which the job class(es) acquire the resource.
