[ndnSIM] Creating a custom cache-replacement policy in CS?

[shijunxiao at email.arizona.edu]

Hi John

ndnSIM 2.1 uses a fork of NFD 0.3.4 release, which contains a ContentStore policy API, and it is somewhat flexible. NFD 0.3.4 offers a priority-fifo policy and a LRU policy, implemented with this policy API. See NFD developer guide for more information.

I saw the incorrect statement on http://ndnsim.net/2.1/cs.html . I have reported ndnSIM Bug 3827, so that ndnSIM developers can correct that statement in the next release.

Yours, Junxiao

The documentation and tutorials say that NFD has a hard coded cache replacement policy and is not flexible.  Then it describes that this is why the ndnSIM 1.0 CS has been ported into 2.0.

Hi John

Can you elaborate on this statement? Exactly what is missing in NFD 0.3.4's ContentStore policy API that is present in ndnSIM 1.0 ContentStore API?
Your answer to this can allow NFD designers to either point out your misunderstand and help you use NFD ContentStore policy API to achieve what you need to do, or improve future versions of NFD so that it becomes more flexible with cache replacement policies.

Yours, Junxiao

Since the NFD Content Store appears to not be flexible with cache replacement policies, I am going to steer away from it.
