Hi folks,

I am experimenting with mobility in NDN and want to evaluate the performance and reliability under intermittent/disconnected networks. NDN-Ping and NDN-Chunks run fine; however, ndnchunks handles single small files (data packet less than 8800 B, if I’m not mistaken).

This is partially incorrect. ndncatchunks/ndnputchunks (collectively referred to as "chunks") can handle files of arbitrary size. A single Data packet can be at most 8800 bytes long, so if the file is larger than that, chunks will split it into segments. You can choose the maximum segment size using the -s/--size option of ndnputchunks.
