Abstract
A node and a method for generating a shortened name robust against a change in a hierarchical name in a Content-Centric Network (CCN) are provided. The method includes receiving a packet requesting content including a hierarchical name of the content, and determining whether a prefix of the hierarchical name is identical to a name of the node. The method further includes generating a shortened name by removing the prefix from the hierarchical name if the prefix is identical to the name component, and changing the hierarchical name to the shortened name. The shortened name is used to check whether the corresponding content is stored in the content cache, to check whether the same content-request packet is already under processing, and to decide an outgoing face to which the content-request packet is transmitted.
