Hi Alex,

I hope you are doing well.

I have come across a problem with hopcounts which is not consistent with
the explanation offered in:
http://ndnsim.net/metric.html#application-level-trace-helper. It is quite
clear that when a packet is satisfied by a cache then the hopcount will be
even while when it is satisfied at the repository then it will be odd.
However, in practice that is not happening. For a sanity check, I ran
ndn-tree-cs-tracers.cc, and attached onto it the AppDelayTracer. Now, even
though I can see CacheHits due to the CSTracer, but I cannot see any
hopcounts in the AppDelayTrace output that are odd.

Has the source been updated to not count the hop from network-level to
application-level for the Interest and Data packets?

With appreciation and thanks,
