REPUTATION-BASED DISCOVERY OF CONTENT OBJECTS

摘要

A content-discovery system allows a node in a Content Centric Networks (CCN) to discover content over CCN. The CCN node can generate an Interest that includes a query for discovering content associated with a given name prefix, and after disseminating the Interest over CCN, can receive a query-result Content Object that includes a listing of matching Content Objects and their reputation information. The CCN node can also process Interests issued by other CCN nodes that would like to discover content. After receiving an Interest comprising a query for discovering content, the CCN node searches a repository for a set of Content Objects that match the query. The CCN node generates a results list that includes the Content Object in the search results and their reputation information. The CCN node then generates and returns a query-result Content Object that includes the Interest's name, and whose payload includes the results list.
