16// [#protodoc-title: Aggregated Discovery Service (ADS)]
17
18// Discovery services for endpoints, clusters, routes,
19// and listeners are retained in the package `envoy.api.v2` for backwards
20// compatibility with existing management servers. New development in discovery
21// services should proceed in the package `envoy.service.discovery.v2`.
22
23// See https://github.com/envoyproxy/envoy-api#apis for a description of the role of
24// ADS and how it is intended to be used by a management server. ADS requests
25// have the same structure as their singleton xDS counterparts, but can
26// multiplex many resource types on a single stream. The type_url in the
27// DiscoveryRequest/DiscoveryResponse provides sufficient information to recover
28// the multiplexed singleton APIs at the Envoy instance and management server.
