Computer system and method for load balancing with selective control

摘要

A computerized method for load balancing in a geographically distributed or clustered system is disclosed. An arbiter assigns clients to nodes. The arbiter partitions clients into groups based on their request load. Each group is dynamically scheduled among nodes, thus avoiding high load groups from being allocated to the same node and overloading the system. If one of the nodes becomes overload, an alarm is generated, so that fewer or no new clients are allocated to the overloaded node.
