[Ns-developers] New branch gjc/ns-3-real

<http://code.nsnam.org/gjc/ns-3-real/>It contains the new experimental
broadcast socket option (needs review but I can't block on the review), a
new RealUdpSocket class that translates NS-3 Socket API calls into real UDP
sockets, and a RealStackHelper which, at least on Linux, possibly also other
unix systems, detects real host interfaces, together with MAC addresses and
IPv4 address, and adds them to a Node as SimpleNetDevice devices.  It's
trivial to get the OLSR model to work on real UDP sockets with this.  E.g.:


  GlobalValue::Bind ("SimulatorImplementationType", StringValue
("ns3::RealtimeSimulatorImpl"));
  GlobalValue::Bind ("ChecksumEnabled", BooleanValue (true));

  OlsrHelper olsr;
  Ipv4StaticRoutingHelper staticRouting;
  Ipv4ListRoutingHelper list;
  list.Add (staticRouting, 0);
  list.Add (olsr, 10);
  RealStackHelper stack;
  stack.SetRoutingHelper (list);

  Ptr<Node> realNode = CreateObject<Node> ();
  stack.Install (realNode);

  Simulator::Run ();


You need of course superuser privileges to run this, because of the OLSR
port under 1024 (for instance, I run with sudo
LD_LIBRARY_PATH=$LD_LIBRARY_PATH ./path/to/program, inside a ./waf shell).
