Google Cloud Service Mesh xDS Control Plane API
Cloud Service Mesh uses the open-source xDS v3 control plane API to distribute configuration to Envoy sidecar proxies and proxyless gRPC clients. Configurations defined via the Network Services and Network Security REST APIs are translated and pushed to connected clients through the xDS protocol, supporting Listener Discovery Service (LDS), Route Discovery Service (RDS), Cluster Discovery Service (CDS), and Endpoint Discovery Service (EDS).
