1.3 追踪框架支持 TraceConnect():链接对象的某个追踪源 TraceConnectWithoutContext():连接对象的某个追踪源,但是不携带上下文信息 TraceDisconnect():断开对象的某个追踪源,不再继续追踪属性的变化和事件的发生 TraceDisconnectWithoutContext():断开不带上下文的某个追踪源 2 TypeId TypeId类的四类核心方法: 构造函数...
bool ok = accessor->ConnectWithoutContext (this, cb); return ok; } Accessor我们之前已经讲过了,是一个在GetTypeId里被调用并生成的一个类型,具体的accessor->ConnectWithoutContext在上面的DoMakeTraceSourceAccessor里有定义,还是通过了SOURCE T::*a这个类型得到了TracedValue在类中的位置,调用了这个类型的Conne...

在函数 TraceInFlight 当中,Config::ConnectWithoutContext就将其与对应的trace target 相连接,其中 /NodeList/1/$ns3::TcpL4Protocol/SocketList/0/BytesInFlight 是target的路径。 网络结构 下图是该实验的网络拓扑结构: 只有一个TCP Sender和一个TCP Receiver,使用的发送器是 BulkSenderHelper,就是指按照尽可能大...

执行某个函数,回调的实现是TraceConnectWithoutContext函数,举 个例子,在我的时延仿真中,输出时延的代码我是这样写的: staticvoid CalculateDelay(Ptr<constPacket>p,constAddress&a ddress) ns3网络仿真 { staticfloatk=0; k++; staticfloatm=-1; staticfloatn=0; ...
The next step is to create two nodes that we will connect via thepoint-to-point link. The NodeContainer is used to do this just as wasdone in first.cc. NodeContainer p2pNodes; p2pNodes.Create (2); 1. 2. Next, we declare another NodeContainer to hold the nodes that will bepart of ...
