计算网络延迟对多个连接的适配器 [英] Compute Network Latency on Multiple Connected Adapters

问题描述

我需要计算系统，该系统有多个连接的适配器上的网络延迟。 我现在用的是System.Net.NetworkInformation.Ping类来ping一个地址，并使用RoundtripTime属性来确定延迟。

这工作得很好。然而在具有多个连接的适配器的系统，我需要 提供的源IP来使用，以确定在每个可用的连接的等待时间。

本类然而，这并不提供一个选项，使用特定的源IP地址来ping

我需要类似于平DOS命令的东西。该命令有-S的选项，使您可以提供一个源IP地址。

有没有一种方法来指定System.Net.NetworkInformation.Ping的源IP地址。该PingOptions类不提供任何这样的选择。

感谢。

解决方案

  //提供任何网址平。
乌里objURL =新的URI（任何URL）;
System.Net.NetworkInformation.Ping objPing =新System.Net.NetworkInformation.Ping（）;
System.Net.NetworkInformation.PingOptions objPingOptn =新System.Net.NetworkInformation.PingOptions（）;

//如果决定在小块一展身手或除法发送数据包
objPingOptn.DontFragment = TRUE;
//创建的32字节的缓冲器。
字符串tPacketData =DummyPacketsDataDummyPacketsData;
byte []的bBuffer = Encoding.ASCII.GetBytes（tPacketData）;
//可以直接如有提供主机名
System.Net.NetworkInformation.PingReply objPingRply = objPing.Send（objURL.Host，120，bBuffer，objPingOptn）;

objPing.Dispose（）;
如果（objPingRply.Status == System.Net.NetworkInformation.IPStatus.Success）
    返回true;
其他
    返回false;
 

I need to calculate the network latency on a system which has multiple connected adapters . I am using the System.Net.NetworkInformation.Ping class to ping an address and use the RoundtripTime property to determine latency.

This works fine. However on a system with multiple connected adapters , I need to provide the source IP to use, to determine the latency on each of the available connections.

This class however does not provide an option to ping using a particular source IP address

I need something similar to the ping DOS command . This command has the option of -S which allows you to provide a source IP address.

Is there a way to specify the source IP address in System.Net.NetworkInformation.Ping. The PingOptions class does not provide any such option .

Thanks.

解决方案

//Provide any URL to ping.
Uri objURL = new Uri("ANY URL");
System.Net.NetworkInformation.Ping objPing = new System.Net.NetworkInformation.Ping();
System.Net.NetworkInformation.PingOptions objPingOptn = new System.Net.NetworkInformation.PingOptions();

//Decides if packet to be sent in a go or divide in small chunks
objPingOptn.DontFragment = true;
//Creating a buffer of 32 bytes.
string tPacketData = "DummyPacketsDataDummyPacketsData";
byte[] bBuffer = Encoding.ASCII.GetBytes(tPacketData);
//Can provide host name directly if available
System.Net.NetworkInformation.PingReply objPingRply = objPing.Send(objURL.Host, 120, bBuffer, objPingOptn);

objPing.Dispose();
if (objPingRply.Status == System.Net.NetworkInformation.IPStatus.Success)
    return true;
else
    return false;
