Abstract:
A load balancing system and a corresponding computer-readable medium are proposed. The load balancing system is used in environments (e.g., implementing a licensing management application) wherein each client is associated with a preferred server storing specific information for the client. Each client periodically detects a workload and a response time of all the servers. The client selects a subset of nearest servers (according to their response times). The server in that subset with the lowest workload is set as an eligible server. Whenever a ratio between the workload of the preferred server and the workload of the eligible server exceeds a predefined threshold value (e.g., 1.1), the client switches to the eligible server (transferring the corresponding specific information). The system of the invention exhibits a slow dynamic, and tends to reach a steady condition (wherein the specific information of the clients is not continuously moved across the system).
