ns3 print 丢包内容的两种方法
1.方法一enable ascii print
AsciiTraceHelper ascii;
pointToPoint.EnableAsciiAll (ascii.CreateFileStream ("myfirst.tr"));

2.方法二 打印packet的metadata
首先enable printing
Packet::EnablePrinting ();然后开始输出
PacketMetadata::ItemIterator metadataIterator = q->BeginItem();
PacketMetadata::Item item;
while (metadataIterator.HasNext())
{
item = metadataIterator.Next();
if(item.tid.GetName()=="ns3::TcpHeader"){
Callback<ObjectBase *> constr = item.tid.GetConstructor();
NS_ASSERT(!constr.IsNull());
// Ptr<> and DynamicCast<> won't work here as all headers are from ObjectBase, not Object
ObjectBase *instance = constr();
NS_ASSERT(instance != 0);
TcpHeader* tcpHeader = dynamic_cast<TcpHeader*> (instance);
NS_ASSERT(tcpHeader != 0);
tcpHeader->Deserialize(item.current);
// The tcp sequence can now obtain the source of the packet
break;
}
}
