分配mx时显示错误的代码。到queu的数据包数

Question

以下代码显示此错误：

msg="Invalid attribute set (MaxSize) on ns3::PointToPointNetDevice", file=../src/core/model/object-factory.cc, line=75
terminate called without an active exception
Command ['/usr/bin/python', 'scratch/python_first_mod2.py', '--SimulatorImplementationType=ns3::VisualSimulatorImpl'] terminated with signal SIGIOT. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

代码：

pointToPoint2.SetQueue ("ns3::DropTailQueue","MaxSize", ns.core.StringValue ("50p"))
pointToPoint2.SetDeviceAttribute("DataRate", ns.core.StringValue ("10Mbps"))
pointToPoint2.SetChannelAttribute("Delay", ns.core.StringValue ("2ms"))

Answer 1

首先尝试实例化队列，设置属性，然后通过SetQueue（）将队列传递给PointToPoint对象。你知道吗

您的代码尝试在ns3::PointToPointNetDevice对象上设置属性“MaxSize”。显然，您尝试为ns3::DropTailQueue设置属性，该属性从类ns3::QueueBase继承该属性。你知道吗
