Technical Overview

Engineering breakdown of Benchmarking Bare-Metal Kubernetes Pod Networking (2162). Bare-metal hardware performance requires isolated kernel parameters, SR-IOV VF allocation, and DPDK-accelerated CNI plugins to achieve line-rate throughput. This article dissects the network stack from NIC firmware to kube-proxy iptables chains, quantifying latency variance under 10GbE/25GbE loads with Cilium eBPF datapath vs. Calico VXLAN overhead.

Methodology

We deployed a 3-node cluster (dual-socket Xeon Gold 6348, 256GB RAM, Mellanox ConnectX-6 Dx) running Kubernetes 1.28 with containerd 1.7. Test pods pinned to dedicated cores via CPU manager static policy. Traffic generated via MoonGen Lua scripts at 14.88Mpps per 10GbE port. Metrics collected through eBPF tracepoints (sock_ops, tcp_retransmit) and Prometheus node-exporter.
