DPDK and RDMA Over Converged Ethernet (RoCEv2) for Real-Time Radar Ingestion

Bypassing standard Linux networking stack overhead to deliver 100 Gbps radar streams directly into GPU memory.

Data Plane Development Kit (DPDK) Poll Mode Drivers

By utilizing DPDK user-space poll-mode drivers, incoming network packets bypass Linux kernel socket buffers, eliminating CPU context switches and memory copies.

Direct GPU DMA via RoCEv2

RDMA Over Converged Ethernet (RoCEv2) writes incoming IQ frames directly into NVIDIA GPU HBM3 memory via PCIe DMA, enabling instant CUDA kernel processing.

Network Latency Reduction Results

Direct GPU RDMA ingestion cut end-to-end packet processing latency from 450 microseconds down to 18 microseconds, allowing 1 kHz radar update rates.
