模拟高延迟/间歇性网络连接

问题描述

我正在使用 The Grinder (在Windows PC上)进行负载测试，我希望模拟不完美的网络条件，以查看对应用程序负载有什么影响，特别是我想查看以下影响:

I'm load testing a network application using The Grinder (on a Windows PC) and I wish to simulate imperfect network conditions in order to see what effect is has on the application load, in particular I'd like to see the effect of:

• 可变的网络延迟时间，因此，不同的客户端不仅具有不同的延迟时间，而且在测试单个客户端期间的延迟可能会有所不同.
• 断开的网络连接-我想模拟突然/随机断开网络连接时发生的情况.

• Variable network latency, so not only do different clients have different latency, but also latency may vary during the test for a single client.
• Dropped network connections - I wish to simulate what happens when a network connection is abruptly / randomly dropped.

最简单的方法是什么?

推荐答案

1. 将Linux机器设置为该计算机的默认路由器.
2. 在Linux机器上安装'netem': http://www.linuxfoundation.org/collaborate/workgroups/networking/netem

1. Setup a Linux box as the default router for this machine.
2. Install 'netem' on the linux box:http://www.linuxfoundation.org/collaborate/workgroups/networking/netem
