Simulate jitter in network

[Andriy Yerofyeyev]

Hello Team,

Can you recommend some software which can work as a bridge between point A and point B and introduce variable delay/jitter/packet loss to transit traffic ?

Any advices will be appreciated.

Hi, See below this post on the software known as WANem. It's designed for use in a lab environment:

Just so you know, both of these are front ends to functionality that is built into the linux kernel. The linux 'tc' command relates to traffic control and supports a few queueing disciplines such as priority queueing and custom queueing. One of the queueing disciplines it supports is called 'netem' and this is what these front ends configure, 'tc qdisc netem'.

If you are familiar with configuring routers at the command line you shouldn't have too much trouble working this out, with a bonus that once you are familiar with the commands you can use any linux system that you can find lying about.

Cheers
