Wire-Speed Packet Capture and Replay at 200 Gbps

Original language description

CESNET (Czech NREN) and Netcope Technologies are ready to demonstrate their NFB-200G2QL smart NIC with Virtex UltraScale+ FPGA specifically designed to push the achievable traffic processing throughput to 200 Gbps in a single card. Unique high-speed DMA engines in the FPGA together with highly optimized Linux drivers enable to achieve 200 Gbps data transfer through two PCIe Gen3 x16 interfaces with minimal CPU overhead. Captured network traffic can be independently distributed among individual cores of two physical CPUs (NUMA nodes) without utilization of QPI. As a result, wire-speed packet capture to the host memory from two fully saturated 100 Gbps Ethernet interfaces (QSFP28+) is achieved and various network monitoring applications can utilize the power of the latest FPGAs and CPUs for data processing. This is especially useful when traffic of both directions of a single 100GbE link needs to be processed. The proposed demonstration shows how the packets can be received from two 100 Gbps Ethernet links at full speed and captured to the host memory at 200 Gbps without any loss. The opposite direction of communication is also shown, i.e. how the packets can be transmitted from the host memory towards the two 100GbE network interfaces. Achieved speeds are demonstrated by counters and gauges showing generated, received/transmitted and captured packets. We also show detailed statistics of CPU load during the packet capture/replay for different packet lengths.
