[ndnSIM] [ndnSIM2.0]: Data packet isn't receiving on the other nodes

[Hitesh Wadekar]

Thank you Alex, it was interest expiration issue.
Also, Thanks for sharing the new NFD docs (
http://named-data.net/techreport/ndn-0021-3-nfd-developer-guide.pdf).

Do we have an ndnSIM IRC where we all can actively chat?

Cheer,
Hitesh
