Maybe I am missing something rather basic, but I don't know so I figured I would ask.
In terms of testing, how sensitive various TDMoE are to BER and packet delay, I am looking into how to simulate delay and random packet dropping at the ethernet level. For these tests, I will probably just run iptables as documented in a similar StackOverflow question. However, although that will work here, I am not sure it will work in a more general case (perhaps testing BER tolerance between Windows servers and the like). So this has got me thinking.
Are there any inexpensive network testing devices that allow one to artificially delay or drop packets in order to stress test protocols and evaluate sensitivity to latency and packet loss?
My requirements are to be able to do this on the ethernet level. I am not looking so much for specific devices, brands, etc. so much as "are their things that do this?" and if so, maybe some general ideas of what they are like. I am mostly looking at building a simple bridge running Linux and iptables to do this. Just wondering if this is the right way to go.
