CONTENT FILTERING FOR INFORMATION CENTRIC NETWORKS

摘要

A method provides filtering of content objects on a per user basis at a gateway node in a content centric networking (CCN) network. The gateway node has a network interface with a network of a user device originating a CCN interest packet. The method includes receiving a CCN interest packet including a CCN name and a user identity, retrieving a content object identified by the CCN name, and retrieving allowed categories of the user. The method further includes retrieving categories of the content object, checking whether allowed categories of the user enable retrieval of the content object based on comparison with the categories of the content object, and forwarding the content object to user in response to the allowed categories enabling retrieval of the content object for the user.
