我使用了一个名为 netem 的工具，它在 Linux 上运行。 它允许您以给定的百分比增加数据包丢失，在数据包内引入延迟并处理数据包重新排序。 基本上它是为了模拟不同的网络而设计的。
启动并运行它所需要的只是一台安装 Linux 并带有几块以太网卡的备用机器。 将其作为桥梁连接起来，并在它们之间运行 netem。 做起来应该很简单。 我在没有 Linux 经验的大学项目中使用了它，但我可能仍然在某处找到了所有设置说明。
I used a tool called netem that runs on linux. It allows you to increase packet loss at a given percentage, introduce delays within packets and handle packet re-ordering. Basically it's designed to emulate different networks.
All you need to get it up and running is a spare machine to install Linux on with a couple of Ethernet cards. Hook it up as a bridge, and run netem between them. Should be quite simple to do. I used it for my University project having no Linux experience, but I've probably still got all the setup instructions somewhere.
Ian 的解决方案似乎是一个非常好的长期解决方案，但听起来有点涉及一些快速测试。 （找到另一台机器，连接它，可能设置路由器等）
我最终只是使用 Net Limiter 并随机将限制手动设置为低得愚蠢的东西（例如 1 字节/秒），这似乎足以满足我们的需求。
Ian's solution seems like a pretty good long term solution, but sounded a little involved for just some quick testing. (finding another machine, hooking it up, possibly setting up router stuff etc)
I ended up just using Net Limiter and randomly set the limit to something stupidly low manually (like 1 byte/sec) and that seems to be sufficient for our needs.

有点复杂设置，但效果很好。

It's a little complicated to setup, but works very well.
