ndnSIM 2.0 is a new release of NS-3 based Named Data Networking (NDN) simulator that went through extensive refactoring and rewriting. The key new features of the new version:
ndnSIM no longer re-implements basic NDN primitives and directly uses implementation 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)
Packet format changed to NDN-TLV
