Deep Dive: Network Service Mesh (NSM)
summary
A Kubernetes-oriented system that wires point-to-point L2/L3 connections using a distributed gRPC control plane and CRDs, avoiding CNI by design so it is orthogonal to CNI. Reference deploy uses DaemonSets and VPP (optional), negotiates mechanisms like memif/vhost-user kernel bypass, establishes tunnels in milliseconds, and exposes an SDK for programmatic connect/close and composable endpoints with built-in IPAM (slash‑30) and Envoy integration. Examples and YAML live in the repo.
