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 a routing policy for content data. The system also receives a packet associated with a piece of content or an interest for the content. Next, the system determines that the structured name included in the packet is within the namespace specified in the routing policy. The system further determines that the packet satisfies the condition in the routing policy. Subsequently, the system routes the packet based on in part the action corresponding to the condition as specified in the routing policy.

Controlling the spread of interests and content in a content centric network

One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network. An HSVLI indicates a piece of content and indicates a hierarchical structure of contiguous components ordered from a most general level to a most specific level. The length of the HSVLI is not fixed. During operation, the system receives a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines forwarding information for the HSVLI based on one or more of: knowledge of content which matches the HSVLI, a forwarding policy, and contextual information about the network. Next, the system configures a forwarding engine with the forwarding information. The system then forwards the packet based on the forwarding information.

Adaptive multi-interface use for content networking

A CCN network node use reputation values for one or more interfaces to determine how to forward an Interest. During operation, the network node can receive an Interest or Content Object via a network interface, determines one or more candidate outbound faces for forwarding the Interest by performing a longest-prefix-matching lookup in a forwarding information base (FIB) using the Interest's name or name prefix as input. A respective FIB entry maps a name prefix to a forwarding rule that includes a corresponding outbound face for the name prefix. The node can determine a reputation value for each of the candidate outbound faces based on reputation information stored in association with the Interest's name or name prefix, and selects a candidate outbound face with a reputation value exceeding a first predetermined threshold. The node can then forward the received Interest via the selected outbound face.

Reputation-based strategy for forwarding and responding to interests over a content centric network

One embodiment of the present invention provides a system for updating link-status information associated with a prefix in an information-centric network (ICN). During operation, a first node in the ICN receives a link-state advertisement (LSA) message from a neighbor node with the LSA message specifying a prefix and an anchor node advertising the specified prefix. The system determines, based on topology information stored on the first node, whether a shortest-path condition is met, and forwards the received LSA message to other neighbors of the first node in response to the shortest-path condition being met.

System and method for efficient name-based content routing using link-state information in information-centric networks

A network node can use reputation values to determine when to forego validating a cached Content Object's authenticity. During operation, the network node can receive an Interest over a Content Centric Network (CCN). If the Content Store includes a matching Content Object that satisfies the Interest, the node obtains the cached Content Object. The node then determines whether the Interest includes a validation token that is to be used to validate the Content Object's authenticity. If so, the node determines a reputation value for the Content Object, such that the reputation value indicates a likelihood that validation of the Content Object's authenticity will be successful. If the network node determines that the reputation value exceeds a predetermined threshold, the node returns the Content Object without validating the Content Object's authenticity.
