[ndnSIM] Problem in Forwarding module

thanks for your reply Spyridon.
I understand that this example is from ndnSIM-v.1, so I installed it and run the example there. It works well but with a customary forwarding strategy not best rout strategy. It would be good if the documentation about this example be correct.
now my question is that why as a good rule of thumb did not use from received nack from upstream face to correct the chosen face? I try to follow it in my work.
I also understand the best rout forwarding strategy do not work well and actually do not choose the least cost link. I tested it in a simple topology as: one consumer, one producer and two path from consumer to producer with different data rate. I unexpectedly saw that the best rout chosen the worse path. Can anyone here tell me why? and is this problem related to forwarding strategy or route calculator?

NFD congestion control implementation is still in progress
as you can see here:
you are looking for has not been implemented yet:
work-around for your own research, you can create a custom
forwarding strategy that would keep track of the occupied
link bandwidth and switch paths once a link is
that this helps,

ndn-congestion-alt-topo-plugin.cpp example with --visualize
option to see how ndn utilize links in congestion situation
but seems the forwarding module do not work correctly and
all of packets transmitted through congested link!!! I
checked the trace file too.
has anyone an idea about this?
I also tested it with a
different topology and receive the same incorrect result.
my ndnSIM is clean and
without any change. I installed it based on ndnSIM website
can be usefull.
