Feature Description

Configurable variables

It is possible to configure:

  • The size of the buffer segments to be used (using HostBufferSegmentSizeRx in the ntservice.ini file – see DN-0449). Possible sizes are 1, 2 and 4 MB, and dynamic size.
    Note: Dynamic segment size is recommended for packet-based interface, while static segment size (1, 2 or 4 MBytes) is recommended for segment-based interface.
    Note: Dynamic segment size does not apply to the Intel® PAC with Intel® Arria® 10 GX FPGA.
  • The number of RX host buffers to be used (using HostBuffersRx in the ntservice.ini file – see DN-0449). Up to 128 host buffers can be configured. The default configuration is 4 host buffers.
    Note: For static segment size (1, 2 or 4 MB), only up to 64 buffers are supported.
  • How filters and hash keys are defined (using the Napatech programming language (NTPL) – see DN-0449).
  • How flows are mapped to host buffers (using the Napatech programming language (NTPL) – see DN-0449).
