Also, cut-through optimization is meaningful when router connect networks with similar (same) MTU characteristics.</div><div class=""><br class=""></div><div class="">---</div><div class="">Alex</div><div class=""><br class=""></div><div><blockquote type="cite" class=""><div class="">On Mar 29, 2015, at 4:28 PM, GTS <<a href="mailto:gts@ics.uci.edu" class="">gts@ics.uci.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

I disagree with the categorical statement below. Hop-by-hop<br class="">
fragmentation is indeed an option for NDN, but it's *not* the only
one.<br class="">
One way to do secure cut-through (end-based and intermediate) <br class="">
(re-)fragmentation is described here:<br class="">

<div class="">yes. this is a typo that we didn’t catch before. The
conclusion meant to highlight that *hop-by-hop* fragmentation
is the only viable option for NDN.</div>
