Actually there is/will be fragmentation in NDN. You can take look at this:
This is just a memo, but it has reviewed the problem and solutions well enough.
But the need for fragmentation in above comes from the fact that MTUs may differ throughout the network. I don't think having large amounts of segments(you say names) be a problem. They could be aggregated easily.

ndnputfile/ndngetfile comes from repo-gn, you might have to install it.
You can also check out ndnputchunk3, this will also do what you want. If
you want I have created a text file sender/receiver by (modifying earlier
producer/sender code) for large chunks of data, more like bulk transfer. I
have tested my code for one sender and one receiver and haven't tested for
more than one receiver(maybe some optimization have to done there)
