Abstract
A novel scheduling method is provided which may be used for rate-based scheduling (e.g., for scheduling flows at some assigned rates in a computer network) or for weighted fair sharing of a common resource (e.g., scheduling weighted jobs in a processor). The method is based on hierarchical application of Relative Error (RE) scheduling. The present method of a Hierarchical RE Scheme (HRE) with complexity O(log(N)), where N is the maximum number of jobs supported by the scheduler, is provided.
