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

对于macOS，有Network Link Conditioner可以模拟可配置的带宽、延迟和丢包。它包含在Xcode的附加工具包中。

Take a look at the NE-ONE Network Emulator which allows you to configure bandwidth, latency, packet loss, packet reordering, packet duplication, packet fragmentation, network congestion and many more impairments so that you can create real-world network conditions in the lab. Different impairments can be configured for the up and downlink so you could have a really good uplink but a really bad downlink experience, great for seeing how the app handles TCP queuing because the acks don't come back in a timely manner and the overall latency therefore increases!

这里有一个专门针对游戏开发者的概述视频http://www.youtube.com/watch?v=DwtqlE7LcrQ，但它说明了它的内容。NE-ONE是使用web浏览器配置的，所以它真的很容易安装和配置-你不需要是一个网络专家:-)

有一个硬件版本- http://www.itrinegy.com/index.php/products/network-emulators/ne-one -或者你可以下载在VMware ESXi Server下运行的虚拟设备(软件)版本。虚拟设备可以从VMware的Solution Exchange - solutionexchange.vmware.com/store/products/ne-one-flex-network-emulator下载

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

为了模拟一个低带宽连接测试网站使用谷歌Chrome浏览器，你可以去网络选项卡在F12工具和选择一个带宽级别来模拟或创建自定义带宽来模拟。

在过去，我使用了使用Linux Netem(网络仿真)功能的桥接。它是高度可配置的——允许引入延迟(第一个例子是WAN)、数据包丢失、损坏等。

我注意到Netem在我的应用程序中工作得非常好，但我也多次使用WANem。提供的可引导的ISO(和虚拟设备映像)非常方便。
