Abstract
One embodiment of the present invention provides a system for facilitating communication in a content centric network (CCN). During operation, the system receives at a first node from an interest owner an interest in a piece of content. The interest indicates a structured name for the content. Furthermore, the name is unique and persistent with respect to the content, and where the name includes authentication information for the content. Next, the system determines whether content available at the first node satisfies the interest. If so, the system sends the content to the interest owner. Otherwise, the system marks the interest as pending, and forwards the interest to a second node in the network based on the interest. After receiving content from the second node in response to the forwarded interest, the system un-marks the interest as pending and sends the content to the interest owner.
