DISTANCE-BASED ROUTING IN AN INFORMATION-CENTRIC NETWORK

One embodiment of the present invention provides a computing system. The computing system includes a processor and a computer-readable storage medium. The computer-readable storage medium stores instructions which when executed by the processor cause the processor to perform a method. The method comprises identifying an identifier of an anchor node associated with a name in an update message received from a neighbor node. The anchor node stores a content object identifiable based on the name independent of the anchor node. The method also comprises determining a valid next-hop neighbor in the ICN for the name based on a sequence number of the update message generated by the anchor node and lexicographic order of an identifier of the neighbor node; and determining whether the anchor node is a designated anchor node based on the validity of the next-hop neighbor and a routing metric for the anchor node.
