Mastering WireGuard Mesh Networking for Clusters (7687)
Technical Overview
Engineering breakdown of Mastering WireGuard Mesh Networking for Clusters (7687). Bare-metal hardware performance requires isolated kernel parameters, careful MTU management, and eBPF‑based telemetry to achieve sub‑millisecond latency across multi‑region clusters. This guide walks through the control‑plane design, key‑rotation automation, and the eBPF programs that enforce policy without sacrificing throughput.
eBPF/XDP kernel filter evaluates TCP/UDP frames directly on server NIC.
