Empowering Edge Software Stack on Arm with High Performance Container Networking Tech
summary
Arm builds a three‑node edge reference cluster and wires Kubernetes to multiple container networking paths, then measures throughput and latency to pick winners. The stack evaluates Calico (kernel stack/BGP routing), Cilium (eBPF dataplane with XDP/iptables offload), SR‑IOV device plugins and a DPDK CNI, plus SmartNIC OVS offload; SR‑IOV reaches near line‑rate across hosts, encapsulation overlays lag, and the team reports concrete tuning knobs and TX/RX settings that materially change performance.
