Advice of Charge in Content Centric Networks

摘要

Advice of charge (AoC) enforcement is implemented in a content centric networking (CCN) gateway. The AoC enforcement receives a CCN interest packet from a user equipment in a network external to the CCN network and looks up a prefix of the CCN name in an AoC table. The AoC enforcement further, in response to determining a match between the prefix of the CCN name and an entry in the AoC table, generates an AoC request and forwarding the AoC request toward an AoC server identified by the entry in the AoC table determined to be the match with the prefix of the CCN name. In response to not determining the match between the prefix of the CCN name and the entry in the AoC table or in response to receiving a purchase accepted response from the AoC server, a CCN object identified by the CCN name is retrieved and forwarded to the user equipment.
