-The ndnSIM is NS-3 module that implements Named Data Networking (NDN) communication model, the clean slate Internet design. ndnSIM is specially optimized for simulation purposes and has a cleaner and more extensible internal structure comparing to the existing NDN implementation (Project CCNx).

 Following the NDN architecture, ndnSIM is implemented as a new network-layer protocol model, which can run on top of any available link-layer protocol model (point-to-point, CSMA, wireless, etc.).

 The current wire format for the Interest and Data packets used by ndnSIM is defined in :ref:`ndnSIM packet format`.
