Policy-based content delivery: An active network approach

Abstract

This paper describes an active network architecture that provides the ability to load code dynamically to facilitate user-based content delivery. The improvements to the base architecture are outlined to define a new architecture that provides flexible content delivery based on specific user preferences. We describe an architecture which allows individual users to define behaviour by specifying content delivery or transcoding proxylets through user-defined policies. This architecture is shown to be non-impacting on client and server architectures, and allowing modification to the type of content delivered as well as to the method in which it is delivered.
