Hi Mohammad,

<div class=""><br class="">

</div>

<div class="">it’s difficult to have a full view of all the content in all (or even nearby only) routers/caches in the network. There are however, ways to discover content off-path as Interests travel upwards towards their destination.</div>

<div class="">Hope these can give some first insights.</div>

Is NDN able to discover the routers which cache the data? if the data cached on different routers in the network, is there away for consumer to know about all these routers?<br class="">
