Link™ Capture Software 12.0.8 release for Linux
2019-12-19 12:32

Link™ Capture Software 12.0 introduces a new feature set with support for Stateful Flow Management on the Napatech NT200A02 SmartNIC. The new feature set is named “Capture Flow Management” and the current feature set is named “Capture/Replay”.

The major new features in the Capture Flow Management feature set are:
    Up to 50 million bidirectional flows
    Flow termination detected in HW, enabling flow shunting or white-listing/black-listing with full offload in HW
    Flow metrics maintained in HW and delivered to the application upon flow termination

Other notes on the Capture Flow Management feature set:
    Supported port speed configurations: 8x10G and 2x40G
    Packet buffering: 1.5GB
    Correlation and deduplication is not included
    Key match is not included

The Napatech driver supports both feature sets, and feature set and port speed configurations are selected through the active FPGA image:
