NS3中UDP吞吐量计算 [英] UDP Throughput Calculation in NS3

问题描述

我在 NS3 中有一个客户端/服务器拓扑结构，我想计算服务器上 UDP 流量的吞吐量.这行代码 sink = StaticCast(tcpServerApp.Get(0)); 不起作用，因为它只能用于计算 TCP 数据包的吞吐量.如何计算服务器上接收到的 UDP 流量的吞吐量?

I have a client/server topology in NS3 and I want to calculate the throughput of UDP traffic on the server. This line of code sink = StaticCast<PacketSink> (tcpServerApp.Get (0)); does not work because it can only be used in calculating the throughput of TCP packets. How can I calculate throughput for the received UDP traffic on the server?

谢谢

推荐答案

感谢您的回答.我实现了代码:

Thanks because of the answer. I implemented the code:

uint64_t rxBytes = 0;
  rxBytes = 1400 * DynamicCast<UdpServer> (ServerApp.Get (0))->GetReceived ();
  double throughput = (rxBytes * 8) / (10 * 1000000.0); //Mbit/s
  std::cout << "throughput = " << throughput << " Mbit/s" << std::end

但是我收到了 SIGSEGV 错误.可能是什么问题?

But I got the SIGSEGV Error. What can be the problem?

谢谢
