[Nfd-dev] <Question>Difference between NFD and NDN router

[Henry Yeh]

Hi All,


I'm studying NDN now, and I want to ask the difference between NFD and NDN router.


The point is that I think routers are NDN routers is due to the fact that they run NFD on them, but the following two documents make me confused.


Page 13 of this tutorial<https://named-data.net/wp-content/uploads/2016/10/1-ndn-overview.pdf> describes the Interest will check Content Store first when it enters NDN routers.


However, the technical report<https://named-data.net/wp-content/uploads/2014/07/NFD-developer-guide.pdf> of NFD describes the Interest will be inserted into PIT first and then check content store.


I think I might misunderstand them; therefore, hope you could kindly explain it for me.


Thanks,

--


Henry
