<P><FONT SIZE=2>Hi Matti,<BR>
<BR>
Actually there is/will be fragmentation in NDN. You can take look at this:<BR>
<A HREF="http://named-data.net/wp-content/uploads/2015/05/ndn-0032-1-ndn-memo-fragmentation.pdf">http://named-data.net/wp-content/uploads/2015/05/ndn-0032-1-ndn-memo-fragmentation.pdf</A><BR>
This is just a memo, but it has reviewed the problem and solutions well enough.<BR>
<BR>
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.<BR>
<BR>
Thanks,<BR>
Sabet<BR>

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