FEDERATED LOAD BALANCING SYSTEM, FEDERATED LOAD BALANCING DEVICE, SERVICE PROVISION DEVICE, FEDERATED LOAD BALANCING METHOD, AND PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a system that achieves load balancing between SPs installed in different domains, and provides authentication results to the SPs for improving convenience.

SOLUTION: The federated load balancing technology includes: authenticating a user by using authentication information of a user stored in advance; selecting, when the user is authenticated, an SP for providing a service by using reliable domain information and service request information; and determining, when two or more SPs are selected, a low-load SP as an SP which responds to a request from a user terminal by using the load information.
