[Ndn-interest] question on request and response

[marwa kareem]

hello ndn team ,

I connect two virtual machines in virtualbox and configure the NFD same
what it written here <https://named-data.net/doc/NFD/current/INSTALL.html>
and run ndnping and ndnpingserver and the results are in the attachments
(picture 1,2)
1- in pic. 1 the rtt starts to be high  13.8 and then decreases to 1.8
then it increases to 2.3  then decreases again to 1.8 why is that?
2- then I used ccnputchunks and ccncatchunks instead of  ndnping and
ndnpingserver (picture 3,4),
I transfer a picture with 11KB , so during the transfer it was cut into 3
chunks, why? is there a specific size for the transfer?
3- in pic. 3 there is a lot of information regarding the transfer such as
RTO, alpha, beta, k, where i can find a description about these parameters?
4- in pic. 5 the RTT has decreased very much after I run the ccncatchunks
for many times, why?

sorry if my questions seem so basic , I'm still learning about the NDN.
thanks in advance.
