Load generation is often used for load testing and provisioning of networks. The Napatech Intelligent Network Adapters support generation of frames at line speed for all frame sizes.
Traffic Load Generation is supported by the Napatech Network Adapters via functionality, such as:
- Host-based Transmit: Enables frames to be transmitted to the network at line speed on any network connection up to 2 x 10 Gbps and beyond with a minimum of host CPU processing.
- Zero-copy Host Interface: Transfer of frames to the host CPU system bypasses the operating system (adapter DMA) resulting in extremely low CPU load.
- Generation of MAC CRC: The adapter can be configured to generate the Ethernet MAC CRC reducing CPU cycles dramatically. It can also be configured to use a user-generated Ethernet MAC CRC enabling the application to generate frames with a bad Ethernet MAC CRC.
Programmable IFG: The Inter Frame Gap (the time delay between Ethernet frames) can be configured, either as a global parameter used by all transmitted frames or individually for each transmitted frame with a typical precision below 40 us.
