On providing broadband contents, to provide enough networks bandwidth is an important. Existing contents delivery network has mainly focused on increasing network bandwidth statically. Therefore, it is not flexible. In this paper, the authors propose Soarin, a novel contents delivery system to increase network bandwidth dynamically by deploying delivery servers in a wide area. Moreover Soarin can use various server deployment policies to deploy delivery servers; it can decide which server is suitable for content distribution. They call the criterion server deployment policy. The authors also propose several kinds of server deployment policies for typical contents delivery services.
