[ndnSIM] Shortest paths

[Chavoosh Ghasemi]

Is there any way to get the delay of links?
It seems you cannot get it through PointToPointChannel as GetDelay method
is protected.


P.S. The following code does not work
    auto t =
dynamic_cast<ns3::PointToPointChannel*>(&(*(transport->GetNetDevice()->GetChannel())));
    t->GetDelay();
