summary

Presents SRNIC, an FPGA prototype RDMA NIC architecture that removes on‑chip structures via protocol header extensions, cache‑free QP scheduling, and memory‑free selective repeat to boost connection density. Implements QPC and MTT only on chip, uses host memory for bitmaps and RIT, and runs at 300 MHz. Achieves 10K performant connections, sustains 97 Gbps and 3.3 μs latency with <5% CPU overhead, and reports 18x normalized connection scalability versus commercial RNICs.
