Rude – Rugged deviation emulator


Rude stress tests IP networks by bringing realistic live network conditions to the lab. Early testing will save time and money in the development phase and will help avoid unpleasant surprises after  network deployment. The accuracy of traffic handling in the tool is achieved through our patented technology. 

Rude can deviate any IP traffic, which makes it suitable for environments ranging from 4G and 5G small cell fronthaul and backhaul networks to Internet-of-Things (IoT) and IMS and streaming services.





Rude can be used to: 


IP network emulation


Simulate the effect of geographical distances or emulate QoS classes.



Emulate user mobility in varying conditions



Emulate various traffic conditions

  • Find system thresholds for levels of deviations
  • Carry out  provocative testing with illegal data
  • Test recovery from abnormal conditions



Rude deviation emulator is an extremely flexible and accurate tool for handling the IP traffic in the way you need it. It comes with an intuitive GUI for setting up the deviations. 



The tool is used as a Man-In-The-Middle device. It is placed between the traffic source and System Under Test, to add deviations to the traffic in real time.   


Flow-based deviations

The deviations are done on targeted flow or flows. This gives you full control on the traffic. It enables targeting the challenges to a single subscriber, or adding delay and jitter only to UDP traffic. 

When you know exactly what happened, you can interpret your test results precisely. You can repeat the exact same scenario to confirm your system verification results. 

The example shows Packet Drop targeted at only on specific type (dotted) traffic. Packets are dropped from those flows only, and the scenario is predictable and repeatable. 



Works well in test automation

Rude can be flexibly integrated into automated test environments.

It can be used by multiple users simultaneously, up to 20 users through a CLI interface.





Rude deviation emulator in short:

Rude is an extremely flexible tool that allows you to modify data to the byte level. The filtering feature enables you to target the deviations to a single data flow. Flow-based deviations ensure that deviations affect each data flow in the same way.



Our Rugged deviation emulator Rude simulates live network scenarios with high precision. Turn your optimized lab network into a realistic environment by introducing latency, jitter, limited bandwidth, packet loss or congestion.

Rude saves time by helping you catch those bugs early in SW development. For better customer satisfaction, test your IP network or service and validate your user experience before launching it . Rude comes in various setups for you to choose from , all of which include  GUI for Linux and Windows platforms.





Breeze is a portable platform for traffic rates up to 1Gbps with electrical connections.



Thunder is an U-rack mountable platform for up to 10Gbps with optical connections



Blizzard is an U-rack mountable platform with up to 100Gbps traffic rates.
