NODE AND METHOD FOR GENERATING SHORTENED NAME ROBUST AGAINST CHANGE IN HIERARCHICAL NAME IN CONTENT-CENTRIC NETWORK (CCN)
First Claim
1. A method of a node included in a content-centric network (CCN) based on a hierarchical name structure, the method comprising:
- receiving a packet requesting content comprising a hierarchical name of the content;
determining whether a prefix of the hierarchical name is identical to a name of the node;
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.

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.

11. A node included in a content-centric network (CCN) based on a hierarchical name structure, the node comprising:
-
a receiving unit configured to receive a packet requesting content comprising a hierarchical name of the content; a determining unit configured to determine whether a prefix of the hierarchical name is identical to a name of the node; a generating unit configured to generate a shortened name by removing the prefix from the hierarchical name if the prefix is identical to the name component; and a changing unit configured to change the hierarchical name to the shortened name. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
