[Mini-NDN] [EXT] Some Questions regarding MiniNDN

Yes.

In a segmented object, each segment packet name has the segment number. If
a later segment arrives early, the consumer can buffer that segment until
after all previous segments have been outputted.

Yes, it's possible using Mini-NDN mid-level API.

It's possible, but most strategies do not behave in this way. Today's
strategies are mostly designed to minimize round trip time. They would
either use only one source or jump between two sources.

I noticed that NFD 0.7.1 has a "random strategy" that may work close to
what you imagined.

hostA bash -c 'nlsrc advertise /A'
hostA bash -c 'echo hello from hostA | ndnpoke /A'
hostB bash -c 'ndnpeek /A'
