Abstract

A load balancing system (3) having a plurality of service servers (7-1 to 7-N) and a load balancer (4) which prevents a service performance from being reduced by an overload of requests on the service servers. The system includes a load balancer (4) and a administration server (5), the load balancer outputs an access log relating to an access to the service server, and the administration server performs statistical operation over the access log. The administration server prepares a service server run schedule on the basis of a result of the statistical operation and informs the load balancer of it. The load balancer controls distribution of a request to the service server according to the informed run schedule.

Description

technical field [0001] The present invention relates to a load distribution system for distributing access to a plurality of server devices, and more specifically, to a method of operating the load distribution device. Background technique [0002] The Internet is spreading rapidly, and it is now possible to provide services such as ticket sales at existing business windows through the Internet. Communication technology is also advancing, and an environment in which the same services can be enjoyed not only from homes and offices but also from mobile phones and the like is being prepared. [0003] Through the Internet, in a server device (hereinafter referred to as a service server device) that provides a service as described above, it is usually necessary to process requests from many client terminals, and one service server device cannot handle all requests. Therefore, for example, as described in Patent Document 1, it has been known that requests from many client termina...
