 Providing anonymity for users is the central goal for the anonymous

 given mechanism provides, there is no such thing as complete anonymity.
 GNUnet's file-sharing implementation allows users to select for each
 operation (publish, search, download) the desired level of anonymity.
 The metric used is the amount of cover traffic available to hide the request.

 routing but imposes no minimal requirements on cover traffic. It is possible
