Network Traffic Generator

Traffic Generation Tool for Benchmarking Performance

Benchmark the Raw Packet Level Performance of Networks and Devices with Classical Performance Measurements

Amplify Traffic to Test Networks and Devices at Scale

Quickly and easily assess complex network topologies by generating line rate stateless traffic and emulating millions of traffic flows. Ensure network performance, QoS policies, and resiliency at scale by stress testing with an extensive mix of applications and protocols.

TrafficEngine Traffic Generation tool


  • Effortlessly configure complex traffic flows to mimic the real traffic on your network.

  • Generate a city-scale of network traffic by amplifying a single flow into millions of flows.

  • Ensure network and device performance even at peak load times with high traffic volume.
  • Identify and resolve performance issues before they reach your customers.

  • Mitigate the risks associated with new application rollouts and system implementations.

  • Troubleshoot crashes and bugs to identify the cause of application failure and build fixes faster.

Simplify Stream-based Traffic Configuration

Create custom streams using the Stream Configuration Wizard in our traffic generation tool or automate testing with RESTful API. Gather real-time statistics on a per port or per stream basis to quickly analyze and optimize device performance with ease.

More Traffic Generation Applications

Capture, reproduce, and amplify production traffic in a controlled lab environment.
