Technical Overview

Engineering breakdown of Scaling Bare-Metal Kubernetes Pod Networking (2075). Bare-metal hardware performance requires isolated kernel parameters, custom CNI plugins, and zero-copy packet processing to achieve sub-microsecond latency at scale.

Architecture Deep Dive

The 2075 stack leverages eBPF‑based datapaths, SR‑IOV for NIC partitioning, and DPDK‑accelerated vSwitches. Each node runs a lightweight cilium‑ebpf agent that programs XDP maps directly on the NIC, bypassing the kernel network stack for pod‑to‑pod traffic.

Kernel Tuning & Sysctl Profile

Critical sysctls for 2075 workloads:

  • net.core.rmem_max=21299200
  • net.core.wmem_max=21299200
  • net.ipv4.tcp_fastopen=3
  • net.core.netdev_max_backlog=250000

These values are applied via a MachineConfig in OpenShift or a DaemonSet with sysctl init containers on vanilla Kubernetes.

CNI Selection: Cilium vs. Calico vs. Custom eBPF

Benchmark matrix (2075 Q1) shows Cilium with XDP‑native mode achieving 1.2M pps per core, Calico eBPF at 950k pps, and a custom DPDK‑CNI at 1.5M pps but with higher operational complexity.

eBPF/XDP kernel filter evaluates TCP/UDP frames directly on server NIC.

Future Outlook: Photonic Interconnects & Kernel‑Bypass NICs

By 2076, silicon‑photonic NICs with integrated P4 pipelines will push pod networking into the terabit regime. The control plane will shift to intent‑based policies compiled directly into NIC firmware, eliminating userspace daemons entirely.
