Napatech NT40A01
4-PORT 1G PCIE GEN2

4 Gbps PACKET CAPTURE AND ANALYSIS

The NT40A01 accelerator provides full packet capture and analysis of Ethernet LAN at 4 Gbps with zero packet loss for all frame sizes. It allows real-time data from multiple points in the network to be captured and merged into a single analysis stream. Transmit or replay of Ethernet traffic at 4 Gbps is provided with full transmission control. NT40A01 can also be used for in-line application acceleration.

Intelligent features for flow identification, filtering and distribution to up to 32 CPU cores accelerate application performance with extremely low CPU load.

Flexible time synchronization support including onboard IEEE 1588-2008 (PTP v2) software PTP stack with dedicated PTP port.
