我在我的Windows电脑上使用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。

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。

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

对于Windows，您可以使用这个应用程序:http://www.softperfect.com/products/connectionemulator/

广域网连接模拟器的Windows 2000, XP, 2003, Vista, 7和2008。

也许这是唯一一个Windows版本。

如果你在linux上，我发现流量控制程序对这类事情有很大的帮助。

LANforge ICE is a network emulator with an emphasis on virtual routing, jitter, corruption and delay. Projects have used it to emulate satellite link, cable and modem connections, and high-speed (10Gbit) wan emulation. You can use a Java GUI to build your virtual networks and generate very detailed reports of the traffic flow. The LANforge products also provide traffic generation features: frame, ethernet, layer-3 and stateful traffic (NFS, http). Recent editions for LANforge have sophisticated WiFi testing features as well.
