Link Impairments#
Labs are meant to be a reflection of real-world scenarios. To make simulated networks exhibit real-life behavior you can set link impairments (delay, jitter, packet loss) on any link that belongs to a container node. Link impairment feature is powered by the tools netem command collection:
These commands allow users to set link impairments (delay, jitter, packet loss) on any link that belongs to a container node and create labs simulating real-world network conditions.
