- Load Generation: A high load of network frames are generated with a specific characteristic and with a reproducible outcome. Load generation is often used for load testing and provisioning of networks.
- Flow Generation: High-level protocol flows (e.g. VoIP or HTTP) are often used for validation or performance testing of systems handling session-oriented traffic. Flow Generation Systems combined with Network Monitoring Systems can be used for network testing, e.g. latency through a network, time fluctuation of the frames through a network.
-
Traffic Replay: Real-life traffic is captured from a network and later replayed for testing purposes. Traffic Replay Systems are typically used for debugging of real-life network problems in a controlled environment.
Common for Network Traffic Generation Systems is the need for Napatech Network Adapter features, such as:
- Line Speed Capture and Transmit
- High-precision Time-stamping
- Frame Classification
- Programmable Filtering
- Coloring/Tagging
- Hash Key Generation
- Multi-CPU Support
- In-line Operation
