summary

An open-source RDMA offload engine for FPGAs that implements RoCEv2 and sustains 100 Gbps line rate on an Alveo U55C, matching commercial RNICs while keeping resource use similar to TCP stacks. Architecture uses decoupled state and streaming control–data separation to support hundreds of Queue Pairs and per-flow offloads. Demonstrations include an on-path AES-CTR encryptor that saturates wire speed and an ML-based deep packet inspection that runs at line rate with 98% accuracy, plus a GPU-facing preprocessing pipeline.
