REPUTATION-BASED DISCOVERY OF CONTENT OBJECTS

摘要

A content-discovery system allows a node in content centric networks (CCN) to discover content over the CCN. The CCN node can generate interest information that includes a query for discovering content associated with a given name prefix, and can receive a query-result content object that includes a list of matching content objects and reputation information of the content objects after disseminating the interest information over the CCN. The CCN node can also process interest information generated by other CCN nodes that would like to discover content. After receiving interest information comprising a query for discovering content, the CCN node searches for a storage device for a set of content objects that match the query. The CCN node generates a result list that includes the content objects in the search result and reputation information of the content objects. The CCN node then generates and returns a query-result content object that includes the name of the interest information, and of which payload includes the result list.
