Thank you for your response

about (2) as I'm working with mini-ndn, mini-ndn creates nlsr itself based on the minindn.conf and I do not exactly know how to change minindn.conf so that in nlsr.conf created by running minindn we have the hello interval of 15 as it's default value is 60.

here is my minindn.conf:

node4: _ hyperbolic-state=off radius=0.0 angle=0.0 network=/ndn router=/%C1.Router/cs/node4 site=/edu/site nlsr-log-level=INFO max-faces-per-prefix=0 nfd-log-level=INFO

Here are my thoughts:

1. Ctime I think does something different than you expect it does. Ctime
controls how long miniNDN waits at starting before checking for
convergence. It is not used after this initial phase.

2. Try changing the hello interval in nlsr.conf and see if that changes
the gap. That will give us more information. Additionally, try tweaking
the wait time in mini-ndn between NFD starts. (minindn/ndn/nfd.py).
Finally, try running the experiments with minindn using a ramdisk as a
working directory, if you can spare the RAM. A suitable ramdisk for this
topology could be as small as 1GB.
