Dear Klaus,<br>
<br><span>
Thank you once again for your great help. This is exactly what I need.<br>
But as I have very bad programming experience, I couldn't able to<br>
configure it properly. Is is possible or permissible to ask you for the<br>
modified cpp & hpp file so that I can just replace with my old files?<br>
<br>

Hello,<br>
you can check out our chunks implementation (a little different from<br>
the NDN cat/put chunks one) that implements a GObject layer for<br>
progress/complete signal if that's usefull for you:<br>

It contains a function printSummary() which might be what you want:<br>
<br>
void<br>
PipelineInterestsFixedWindow::<wbr>printSummary() const<br>

1000000; // in ms<br>
double throughput = (8 * m_receivedSize * 1000) / timePassed;<br>
std::string throughputUnit;<br>
<br>
computeThroughput(throughput, throughputUnit);<br>
<br>
std::cerr << "\nAll segments have been received.\n"<br>

Dear Klaus,<br>
<br>
Thank you so much for your reply. File transfer / retrieval<br>
is not the<br>
problem. Problem is retrieval time (millisecond).<br>
<br>
I have already tried ndncatchunks / ndnputchunks. But these<br>
doesn't<br>
provide me any information about download time / retrieval<br>
time of the<br>
contents either. Is there any other idea ?<br>
<br>
<br>
Best regards<br>

Hello Everyone,<br>
<br>
I hope all of you are doing great. I have a very<br>
small question<br>
which I<br>
couldn't find any solution yet. I believe this is<br>
the right<br>
place to ask<br>
about.<br>
<br>
I have installed nfd, ndn-cxx and Repo-ng on two of<br>
computers<br>
willing to<br>
insert & retrieve data to & from data repository. I<br>
have done this<br>
successfully using ndnputfile & ndngetfile command.<br>
But after<br>
retrieving any data using "ndngetfile" command, it<br>
doesn't show<br>
me any<br>
message regarding how much time it needed to fetch<br>
the required data<br>
from the repository. Can anyone help me regarding<br>
that? How can<br>
I see<br>
the download time?<br>
<br>
Here is an example. When I retrieve a file from one<br>
computer to<br>
other,<br>
ndngetfile shows the following message:<br>
<br>
ndngetfile /example/data/1/test.txt<br>
<br>
<br>
INFO: End of file is reached.<br>
INFO: Total # of segments received: 188<br>
INFO: Total # bytes of content received: 187537<br>
<br>
On the above, there are no information about<br>
retrieve/download<br>
time of<br>
the received data. How can I see retrieve/download<br>
time? I will<br>
be glad<br>
to have valuable reply from yours.<br>
<br>
With regards<br>
Muhammad Toufiqul<br>
