我们需要对我们系统进行一些压力测试,我们希望能够模拟非理想的情况:象相对、垃圾等。 我们尤其希望模拟一个手机网络的数据行为。
你们是否知道任何能够发挥作用的硬件/软件/两种解决办法?

理想的情况是,你会从真正的模拟器(例如<代码>ns3)那里获得某种关于半成像的想法。 或写一 yourself。
此外,您还可使用在QoS中设置的、提供<代码>netem模块的、可用于这些用途的六氯环己烷舱。 <代码>netem通过推广广域网的特性,为测试协议提供网络推广功能。 目前的版本包括可变的延误(垃圾)、损失、包装腐败、重复和重新排序。 它支持以分配为基础的选择,或者说你可以在一段时间内用文字改变某些价值观。
Wifi card with an older access point/router, simply take the test station to the edge of the range and you should be able to reliably cause the connection to fail and reconnect. Only reason I sugest an older model is that the range generally weren t that fantastic on the older "802.11b" stuff.
但是,除了只是失去联系外,我不相信你能够利用这一装置来检验手机连接的某些特性,而是应该发挥作用。
If you are in the US, an iPhone on AT&T would probably do it..
或许需要大致如下的内容:
USRP Board, OpenBTS, TrixBox/Asterisk
您可以查到开放式的BTS(http:// openbts.sourceforge.net/),看看它是否将做你们需要做的事情。 你可以把美国退休人员委员会作为塔子使用,然后使用它类似于回落。 我确实知道,上述组合将使电话能够像一个手机塔(见BuringMan/DEFCON 18)连接起来,因此从理论上讲,它应当允许你广播,以缓解频谱。
OpenBTS-UMTS include 3G data http://openbts.org/w/index.php?title=OpenBTS-UMTS You can download and compile on Ubuntu 16.04, there is some issue with dependencies on Ubuntu 18.04. About hardware, i used both Ettus USRP N210 and X310.
