我一直在寻找一种易于使用的工具来进行这种类型的测试。前几天我偶然发现了这个:网络延迟模拟器

如果你用的是Windows系统，你应该试试。它超级容易设置和开始，而且似乎工作得很好。可以自定义各个方向的带宽、时延和丢包。另一个非常好的事情是，你可以定义“流量匹配条件”，这样它只影响你想要它的流量。是的，而且是免费的。

查尔斯

我遇到了Charles web调试代理应用程序，并在模拟网络延迟方面取得了巨大的成功。它可以在Windows、Mac和Linux上运行。

Bandwidth throttle / Bandwidth simulator Charles can be used to adjust the bandwidth and latency of your Internet connection. This enables you to simulate modem conditions using your high-speed connection. The bandwidth may be throttled to any arbitrary bytes per second. This enables any connection speed to be simulated. The latency may also be set to any arbitrary number of milliseconds. The latency delay simulates the latency experienced on slower connections, that is the delay between making a request and the request being received at the other end.

虚拟网

您也可以使用vmware来运行BSD或Linux，并尝试本文(DummyNet)或本文。

另一个客户端程序(仅限Windows)是NetLimiter - http://www.netlimiter.com

我想我找到我想要的了。也许你可以让查尔斯代理或者慢慢来。希望能有所帮助。

您可以试试这个:CovenantSQL/GNTE 就像这样写YAML:

group:
  - 
    name: china
    nodes:
      - 
        ip: 10.250.1.2
        cmd: "cd /scripts && ./YourBin args"
      - 
        ip: 10.250.1.3
        cmd: "cd /scripts && ./YourBin args"
    delay: "100ms 10ms 30%"
    loss: "1% 10%"
  - 
    name: us
    nodes:
      - 
        ip: 10.250.2.2
        cmd: "cd /scripts && ./YourBin args"
      - 
        ip: 10.250.2.3
        cmd: "cd /scripts && ./YourBin args"
    delay: "1000ms 10ms 30%"
    loss: "1% 10%"

network:
  -
    groups:
      - china
      - us
    delay: "200ms 10ms 1%"
    corrupt: "0.2%"
    rate: "10mbit"

运行。/generate scripts/your.yaml

使用Fiddler在Windows上找到了这个(免费解决方案) http://www.logic-worx.com/index.php/tools-and-apps/fiddler-connection-simulator/
