NT40A11-NEBS

Packet Capture and Replay
Use cutting-edge SmartNIC technology to add real-time line- rate performance to your application. The NT40A11 SmartNIC provides full packet capture of network data at 40 Gbps with zero packet loss. Nanosecond precision time-stamping and merge of packets from multiple ports ensures correct timing and sequencing of packets. The NT40A11 SmartNIC can also be used for 100% packet replay with nanosecond precision of all networking traffic for analytics, testing and simulation.

The NT40A11 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 NT40A11 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. Stateless flow processing with support for up to 36,000 flows enables CPU-hungry applications to intelligently select exactly which flows to process and which to ignore.
