ndn-dissect is an NDN packet format inspector. It reads zero or more NDN packets from either an input file or the standard input, and displays the Type-Length-Value (TLV) structure of those packets on the standard output.
Usage example:
echo 'HELLO WORLD' | ndnpoke ndn:/localhost/demo/hello
ndnpeek ndn:/localhost/demo/hello | ndn-dissect
