<div dir="ltr">hi，thank you for your answers . Since i define a new packet,so when i use 'ndn->GetNFaces ()' sending to all faces, when the node recevice the packet ,it cannot get the type of my new packet, i define the new packet in ndn-header-helper.cc ndn-header-helper.h , so what should i do ? </div>
