Emulating geographical distances, including satellite communication
Emulating challenging network conditions, such as bandwidth limitation, line break, and bursty traffic
Emulation malformed and broken packets to test system robustness and response to unexpected errors

Suitable for any IP-based networks:

Testing telecom network elements such as LTE and 5G
LAN testing
WAN testing
Industrial networks with Modbus TCP

Rude the network emulation tool

Rude brings the field to the lab

The Rude tool emulates any live network challenge with vast amount of flows in the lab. It offers extreme accuracy, repeatability and a byte-level control of the traffic.
You can use it to create pre-planned, time-varying scenarios. Also, you can change the parameters on the go as you proceed with your testing.

Create exactly the testing scenario you need

Rude allows you to target the deviations selectively. Its filtering function allows you to choose the exact traffic and the very byte you want to deviate. You can create rules for how to deviate the traffic. This means you can simultaneously add packet drop to all UDP traffic and add fragmentation to all traffic from a specific IP address.

Select the device for your needs

The Rude deviation emulator has an easy-to-use GUI and it is also fully compatible with test automation systems. Depending on your testing needs, you can choose a light, portable device with 1 Gbps line rate, or an U-rack mountable powerful device with up to 25 Gbps line rate.
