   Spyros and John,Thank you for your sharing and suggestion  .It is quite helpful for me,as I have spent much time to study  ns3::ndn::ContentStore .
   If I want to refresh all the CS table every 1 second, Can you give me some advice ? It seems that the NDNSim api document has no related content. Should I study the NS-3 source code.Thank you very much!
   Merry Christmas

By no means do I claim to be an expert in this simulator (yet!), but I have been taking and trying to organize notes about using it.

Please see page 9 in the attached PDF.  I hope to eventually more fully organize this document after adding a significant amount more, adding a table of contents, etc.

But hopefully this helps some people even in its current, very unedited and minimal state.

personally, I feel it would be easier for you to use the CS of NFD. 

You will have to create your own class that will derive from the Policy class of NFD.

Hope that this helps.

Hello :
  I am trying to realize a cache replacement policy on ndnSIM .The new policy is based on lfu policy.  According to the api document I found that
 1)  The ns3::ndn::ContentStore has realized lfu policy , but the code is quite complex,including trie.hpp、tire-with-policy.hpp、lfu-policy.hpp and so on
2)  The nfd::cs::Cs  hasn't realized lfu policy,but the code seems easier.
So which kind of contentstore is easier to realize my policy,   ns3::ndn::ContentStore or nfd::cs::Cs  ?And how to  realize a cache replacement policy,Think you very much!
