Which will lead to modifying ndn-header, right? But header in v 2.1 is much simpler than in v 1. What has been changed here?</p><p dir="ltr" class="">Thanks,<br class="">

The wire encoding is embedded directly in each of the data structure: ndn-cxx/src/interest.cpp, ndn-cxx/src/data.cpp, etc. Some general-purpose wire-encoding functions are in ndn-cxx/src/encoding.<br class="">

Currently I have a simulation in which has some modifications in model/ndn-interest.h/.cc, model/wire/ndnsim.h/.cc, ndn.cxx/detail/pending-interests-container.h, model/fw/ndn-forwarding-strategy.h/.cc. I know NFD is being used directly in ndnSIM 2.1 and there has been some changes in ndn-cxx. But honestly I'm not much familiar with them and need some guide.<br class="">
