Thanks for bringing good point. I did notice there are different
ways for handling link failures.<br>
In NLSR implementation as well as published paper, they use taking
one node down<br>
instead of link fails. But in Ndnsim, uses the link down but two
nodes still can communicate<br>
with others.<br>
<br>
One more question, in ndnsim example, both bestroute and </font>calculateallpossible
route appear<br>
in the main file, then does it account for ?<br>

<pre wrap="">As far as I know, Link failures are, as per the name, LINK failures, and not
node failures.
This means that in theory two nodes can still communicate via alternate
routes.
However, this behaviour depends on the forwarding strategy you use. If you
are using ndnSIM 2.0 + NFD with BestRoute, you might not be able to
experience this behaviour, if you use Broadcast +
CalculateAllPossibleRoutes() you should see the behaviour.
