summary
An open source CNI called SPID extends macvlan and SR-IOV to provide unified RDMA-friendly networking with IPAM, clusterIP access, multi-interface routing and IB conflict/gateway checks. It runs on VMs and public clouds and integrates with Calico/Cilium. A stress test creates 1,000 simultaneous ports, revealing improved IPAM stability; measured gains reach ~25% lower latency and ~15% higher throughput versus Nvidia network-operator, demonstrating the approach works in practice.
