强制丢包 [英] Forcing packet loss

问题描述

出于测试目的，为了确定协议实现在丢包的情况下的行为，我想在我的一个网络设备上强制丢包.具体来说，我希望能够调整丢包率，介于0％和100％之间.我对iptables有一点经验，在我看来我应该可以使用iptables来实现它，但是我却没有能够做到.虽然实现100％的数据包丢失不是问题；).有关如何执行此操作的任何想法?

For testing purposes, to determine how a protocol implementation behaves in the presence of packet loss, I would like to force packet loss on one of my network devices. Specifically, I would like to be able to tune the packet loss anywhere between 0% and 100%. I have a little experience with iptables and it seems to me I should be able to achieve it using that, but I haven't been able to. Achieving 100% packet loss is not a problem though ;). Any ideas on how to do this?

推荐答案

查看 iptables'统计模块.

我猜是这样的

iptables -A FORWARD -m statistic --mode random --probability 0.5 -j DROP

应该在路由器上完成任务.

should do the trick on a router.
