Abstract

A GUI and CDN server device provide user modifiable selections of preferences for delivery treatment, and map the user selections to technical operational parameters in the CDN servers for effecting the requested delivery treatment. Users typically find it beneficial to interact with a file (content) entity in terms of the user visible delivery treatment. The server device provides the ability to define the delivery treatment according to the manner in which the user finds most beneficial. However, the CDN operational parameters for effecting such delivery are not readily available or understood by a typical user. Using the GUI, the CDN server identifies a content entity, and receives at least one user selection variable indicative of delivery treatment of the identified content entity. A correlator maps the received user selections to operational parameters according a set of rules, and a delivery engine effects delivery of the content entity according to the mapped operational parameters to provide delivery results according to the preferred delivery treatment.
