[Mini-NDN] Setting cache size for hosts

[Andre]

Hello everyone,


I am running a set of experiments to evaluate the impact of different 
cache sizes on nodes by running consumers and producers around a set of 
data with different payload sizes. To set the cache on the topology 
file, I'm using the cache parameter as follows:

[nodes]
a1: _ radius=0.5 angle=2.64159265359
b1: _ cache=0 radius=0.6 angle=3.64159265359
c1: _ cache=1 radius=1 angle=1.57079632679
d1: _ radius=1 angle=4.71238898038
[links]
a1:b1 delay=10ms
a1:c1 delay=10ms
b1:d1 delay=500ms


The topology seems to be correctly parsed, as the hostnames match and 
the first transmission times make sense. However, setting a node with 
cache=0 or cache=1, does not seem to have an impact since it still 
manages to keep data in its local cache, resulting in very low 
transmission times once the data has been received for the first time.

[main] reading results for consumer node=b1
[readResultFile] <Transmission> interest=/C2Data/a1/C2Data-1-Type1, 
timeDiff=57186.000000, info=DATA, timeSinceEpoch=04/11/2020 02:01:05.653857
[readResultFile] <Transmission> interest=/C2Data/a1/C2Data-1-Type1, 
timeDiff=599.000000, info=DATA, timeSinceEpoch=04/11/2020 02:01:09.212475
[readResultFile] <Transmission> interest=/C2Data/a1/C2Data-1-Type1, 
timeDiff=683.000000, info=DATA, timeSinceEpoch=04/11/2020 02:01:10.579962
[readResultFile] <Transmission> interest=/C2Data/a1/C2Data-1-Type1, 
timeDiff=704.000000, info=DATA, timeSinceEpoch=04/11/2020 02:01:13.073228


So I'm wondering if there is some conceptual fault to my setup, or maybe 
there is an error to the way I used the topology file (which I have 
based on the now deprecated minindnedit) to set the cache.


Thanks in advance,
