[Mini-NDN] Topology angles and radius & Interest-Data Packets' metrics

[Αστεριος Παρλιτσης]

  Hello again and thanks a lot for the fast answer,

 1) After running the given topology configuration with the mnndn.py  
and any other experiment I get the error below:

2) The local cache was not the issue and I eventually solved the  
problem by following the way metrics are being gathered in ndnping at  
the ndn-tools libraries but thanks again anyway.

Sergio
