摘要

A demand on a server farm or local area network for a farm or network resource is satisfied. The farm or network has a demand director server, a first resource server having a first resource, and a second resource server having a second, different, resource. The director server is aware of what resources are held on the first and second resource servers. In response to a request for one of the first and second resources, one of the first and second resource servers is selected to serve out the requested resource and direct the request to the selected one of the first and second resource servers. The demand server selects an appropriate one of the resource servers to receive the request using its knowledge of where the requested resource is located.
