Data Sheet

Packet Capture and Replay
Use cutting-edge SmartNIC technology to add real-time line-rate performance to your application. The NT400D11 SmartNIC provides full packet capture of network data at 200 Gbps with zero packet loss. Nanosecond precision time-stamping and merging of packets from multiple ports ensures correct timing and sequencing of packets. The SmartNIC can also be used for 100% packet replay with nanosecond precision of all networking traffic for analytics, testing and simulation. The PCIe4 ×16 host interface supports full-duplex 2 × 100G packet transfer between network ports and server memory.

The NT400D11 SmartNIC enables full utilization of CPU cores through advanced receive side scaling with support for tunneling protocols, such as GTP, IP-in-IP, NVGRE and VxLAN. The NT400D11 SmartNIC can also remove duplicate packets, slice packets, and filter packets to reduce the amount of data and thereby offload the server system and applications.

Stateful flow processing with support for up to 140 million flows enables CPU-hungry applications, such as Suricata, to intelligently select exactly which flows to process and which to ignore. Flow records are maintained for all flows and reported to the application.
