Intro: Network Service Mesh (NSM)
summary
Network Service Mesh claims to bring cloud‑native L2/L3 networking by mapping a service‑mesh model to packet payloads and by letting pods request named network services (VPNs, SR‑IOV VFs, multi‑interfaces, on‑prem bridges) via a pod annotation. It uses the Kubernetes API server as a registry, a small daemonset of network service managers (typically one per node) that peer over gRPC to negotiate virtual wires, leaves CNI untouched, is deployable with helm install NSM, and runs today across public clouds and bare‑metal CI.
