DPDK Summit APAC 2024

As 400G wire speed becomes more widely adopted, the need to monitor traffic at 400G is growing daily. DPDK can be a great help to achieve this speed as it provides excellent throughput results. However, monitoring packets at 400G can be challenging, so hardware acceleration also comes in handy. FPGA chips are a suitable option because they can be programmed to perform hardware offload and are powerful enough to support the processing pipeline even at 400G. Developers at CESNET have designed the first 400G FPGA-based SmartNIC that supports DPDK. It contains the Intel Agilex 7 FPGA, which provides enough resources to implement a processing pipeline. This pipeline is able to mark and filter packets and much more at 400 Gbps. It can be configured via RTE flow to help accelerate monitoring as well as many other tasks.
