Projects / WANsim


WANsim allows you to simulate (more accurately, emulate) a WAN connection. In particular, it allows a user to change the emulated WAN speed, latency, variation, packet loss, packet duplication, and packet corruption aspects. It is configured as a network bridge that is established at boot time and uses the Linux Kernel NETEM functionality to accomplish its goals. Although relatively well documented, this functionality is not the easiest to use. WANsim wraps it into a simple to use script.
