[ndnSIM] A Problem About NS-3 Object

[Alex Afanasyev]

Hi!

I'm not sure how your code compiles.  "Ptr<InterestSatisfiedRate> interestSatisfiedRate = factory.Create();"  should fail, since "factory.Create()" creates Ptr<Object> which needs to be dynamically casted to be assigned as InterestSatisfiedRate.

If the code compiles but it fails at some point, my recommendation would be to use gdb to see what exactly is going wrong.
