Napatech’s implementation
This table shows Napatech’s implementation of the pcap_stat structure.
| Counter | Description |
|---|---|
| ps_recv | Count the number of frames received by WinPcap before the PCAP filter. |
| ps_drop | Count all frames dropped by the NT Driver software. Frames might be dropped if streams are shared and opened with host buffer allowance < 100%. |
| ps_ifdrop | Count the number of frames lost due to host buffer overrun for the actual stream. If multiple host buffers are attached to the stream ID used in the actual WinPcap device (merging), the individual drop counters are combined into the ps_ifdrop counter. |
