[ndnSIM] Changing the BW on Link during sim

[Ahmed Sadek]

Dear All,

I wanted to change the BW on link during sim, I found this method in a
previous email Here
<http://www.lists.cs.ucla.edu/pipermail/ndnsim/2013-March/000297.html>

so now I have this method:

// Set the Data Rate of a given Device.
void setDataRate(Ptr<NetDevice > nd, std::string DR)
{
  Ptr < Channel > channel = nd->GetChannel();
  Ptr<NetDevice> toDev = channel->GetDevice (1);
  Ptr<NetDevice> fromDev = channel->GetDevice (0);

  toDev->SetAttribute ("DataRate", StringValue (DR));
  fromDev->SetAttribute ("DataRate", StringValue (DR));
}

And was wondering, is there a simpler method to take advantage of point to
point device method Here
<https://www.nsnam.org/doxygen/classns3_1_1_point_to_point_net_device.html#adc4e5973337c576a2352e261cd844686>
 (

pointToPoint.SetDeviceAttribute ("DataRate", StringValue ("5Mbps"));

), can't we cast *netDevice *to *PointToPointNetDevice *or something
similar ?

Thanks!
Ahmed
