Content based routing in a packet switched network

摘要

One embodiment of the present invention provides a system for controlling the spread of interests and content in a content centric network (CCN). During operation, the system maintains (200) a routing policy for content data. The system also receives (210) a packet associated with a piece of content or an interest for the content. Next, the system determines (220) that the structured name included in the packet is within the namespace specified in the routing policy. The system further determines (230) that the packet satisfies the condition in the routing policy. Subsequently, the system routes (240) the packet based on in part the action corresponding to the condition as specified in the routing policy.
