<br>
If that is the case, you can take a look at forwarding strategies(Adaptive Forwarding paper which you can find it on <a href="http://named-data.net" target="_blank">named-data.net</a>) and also Link State Routing Protocol(NLSR).</font></p></div><div><p><font size="2"><br>
What you're saying is not exactly the way ndn network works. Initial flooding could be a solution in LANs, maybe. But in large scales, no.<br>
<br>
Thanks,<br>

The NDN papers that I have read thus far seem to suggest that a router<br>
receives an interest on a given face and then forwards the interest out of<br>
its other faces. My impression is that this occurs at each router in the<br>
network until the interest reaches the origin. As the data returns to the<br>
client, all routers will learn the path based on the data incoming face.<br>
Routers could then cease flooding once there is a known path. Clearly, my<br>
understanding may be incorrect as I have only been researching NDN for a<br>
week.<br>
