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。

我在我的Windows电脑上使用NetBalancer。

http://seriousbit.com/netbalancer/

2017-10-07更新:NetBalancer最新免费版本为9.2.7。该程序有一个硬编码的截止日期。在启动NetBalancer服务之前，您需要在2016-10-18之前调回系统时钟。详情请参阅本文。

我会尝试在linux上使用netem。有了它，你可以模拟额外的延迟、损坏、丢包和复制。它甚至可以用在环回设备上。

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/

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

http://www.shunra.com上有一个产品叫做VE Desktop，可以用来模拟不同的网络条件。它允许你用一个简单的UI调整延迟、带宽和丢包。唯一需要注意的是，它不是免费的。希望这能有所帮助。
