Thank you Alex, it was interest expiration issue.<br>
Also, Thanks for sharing the new NFD docs (<br>

<br>
Do we have an ndnSIM IRC where we all can actively chat?<br>

Cheer,<br>

Hello<br>
My project involves a reactive mechanism for cache poisoning in ndn. And I<br>
need some help in getting hold of the number of exclusions made for an<br>
interest and also as to how to add exclusions to an interest.Please help me<br>
on this.<br>
<br>
Thank you<br>

Hi Adithya,<br>
<br>
Can you define more precisely "the number of exclusions"?<br>
<br>
As for attaching some information. For simulation purposes, you can always use NS-3 packet tags to add/retrieve arbitrary information to any packet.<br>
<br>

Hi,<br>
<br>
Considering a large catalog (10? prefixes), "ndnGlobalRoutingHelper.CalculateRoutes ()" creates an infinite loop and crashes the system. My scenario consists of 300 nodes and I use ndnSIM 1.0.<br>
<br>
Any solution to resolve this problem , please?<br>
Are there any way to use ShortestPath without using the ndnGlobalRoutingHelper ?<br>
<br>
<br>
Best Regards<br>
<br>
<br>

<br>
Double check that you have build NS-3/ndnSIM in optimized mode. Implementation of CalculateRoutes internally uses Dijkstra algorithm from Boost graph library (which is known to be extremely slow in debug mode). It should be a problem for this number of prefixes and nodes.<br>
<br>
If still fails, you can compute all routes and prefixes offline and install them directly using FibHelper.<br>
