<title>RE: [Ndn-interest] Package Fragmentation in NDN</title>
<div>
<!-- Converted from text/plain format --><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>
