[ndnSIM] how to disable a link

[Alex Afanasyev]

Hi Xiaoke,

The approaches are not wrong, you just need to add a little bit of C++ syntax craziness to it :)

Simulator::Schedule(Seconds(hd), &ns3::ndn::Face::SetUp, face1, false);
Simulator::Schedule(Seconds(hd), &ns3::ndn::Face::SetUp, face2, false);

Or, if you define the FailLink function (as a global function or static in some class), you can do a little bit simpler things
void
FailLinks (Ptr<Node> node1, Ptr<Node> node2)

Simulator::Schedule (Seconds (10.0), FailLinks, Names::Find<Node> ("node1"), Names::Find<Node> ("node2"));


I haven't checked, but I hope this code should compile. Let me know if it doesn't, so I'll double check.
