Abstract
The present invention relates to a method and node for efficiently distributing electronic content in a content distribution network (CDN) comprising a plurality of cache nodes.Embodiments of the present invention include a virtual node logically representing a set of cache nodes. The set of cache nodes is in turn defined based on an internal communication cost between the cache nodes. In each of the cache nodes represented by the virtual node statistics regarding content requests is collected, and based on this statistics it is determined whether specific content is to be cached in the virtual node or not. If it is determined to cache specific content in the virtual node, the specific content may be caused to be cached in one or more of the cache nodes represented by the virtual node.
