METHOD FOR REDUCING VARIABILITY AND OSCILLATIONS IN LOAD BALANCING RECOMMENDATIONS USING HISTORICAL VALUES AND WORKLOAD METRICS

摘要

The present invention provides a method of preventing harmful variability and oscillation in weight based, dynamic load balancing environments. More specifically, the present invention relates to methods to effectively determine the magnitude of weight changes in dynamic load balancing environments based on the workload magnitude and server farm capacity. This method depends on the development of new multi-system characteristics such as a relative workload metric to characterize the workload of the system relative to the collective capacity of all of the systems to handle the workload.
