A new release of NS-3 based Named Data Networking (NDN) simulator went through extensive refactoring and rewriting. The key new features of the new version:

• Packet format changed to NDN Packet Specification

• ndnSIM uses implementation of basic NDN primitives from ndn-cxx library (NDN C++ library with eXperimental eXtensions)

• All NDN forwarding and management is implemented directly using source code of Named Data Networking Forwarding Daemon (NFD)

• Allows simulation of real applications written against ndn-cxx library
