[ndnSIM] ndn cache replace policy

[gc199211]

Dear John,Spyros:
   《ndnSIM-Things I have learned》 is quite helpful for me.Thank you for your help.But I still have some problems. In order to keep  topology node information along the interest forwarding path ,I need to get node id in  NFD/daemon/fw/forward.cpp. However,I haven't found the API yet. Based on 《ndnSIM-Things I have learned》 ,we can get the forward instance by node id  in jpd-test.cpp:
   

      Can I get the node id by forward instance in the opposite way? How can I get node id in Forward::onOutgoingInterest(...) ?Thank you very much!

Greetings,



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 PDF on my Google Drive:

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.


Thanks,


John

Hi,


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!
