<p>A process for selecting, in a content delivery network having at least two surrogate servers delivering content over a network, a surrogate server adapted to deliver content requested by a user. First, the network is divided into subnetworks; upon request of the user, the process finds (4) a subnetwork of the user. Based on this subnetwork, the process then determines (8) the surrogate server closest to the subnetwork of the user. The process then checks (10) whether the closest surrogate server has the content requested by the user. If this is the case, the closest surrogate server is selected. Else, the process loops by passing to the next closest surrogate server, and checking whether it has the content requested by the user.</p> |
