# xDS API Working Group (xDS-WG) |
|
|
|
# Goal |
|
|
|
The objective of the xDS API Working Group (xDS-WG) is to bring together parties |
|
across the industry interested in a common control and configuration API for |
|
data plane proxies and load balancers, based on the xDS APIs. |
|
|
|
# Vision |
|
|
|
The xDS vision is one of a universal data plane API, articulated at |
|
[https://blog.envoyproxy.io/the-universal-data-plane-api-d15cec7a](https://blog.envoyproxy.io/the-universal-data-plane-api-d15cec7a). |
|
xDS aims to provide a set of APIs that provide the de facto standard for L4/L7 |
|
data plane configuration, similar to the role played by OpenFlow at L2/L3/L4 in |
|
SDN. |
|
|
|
The [existing Envoy xDS |
|
APIs](https://github.com/envoyproxy/envoy/tree/main/api) constitute the basis |
|
for this vision and will incrementally evolve towards supporting a goal of |
|
client neutrality. We will evolve the xDS APIs to support additional clients, |
|
for example data plane proxies beyond Envoy, proxyless service mesh libraries, |
|
hardware load balancers, mobile clients and beyond. We will strive to be vendor |
|
and implementation agnostic to the degree possible while not regressing on |
|
support for data plane components that have committed to xDS in production |
|
(Envoy & gRPC to date). |
|
|
|
The xDS APIs have two delineated aspects, a transport protocol and data model, |
|
The xDS transport protocol provides a low latency versioned streaming gRPC |
|
delivery of xDS resources. The data model covers common data plane concerns such |
|
as service discovery, load balancing assignments, routing discovery, listener |
|
configuration, secret discovery, load reporting, health check delegation, etc. |
|
|
|
# Repository structure |
|
|
|
The xDS APIs are split between this repository and |
|
https://github.com/envoyproxy/envoy/tree/main/api. Our long-term goal is to |
|
move the entire API to this repository, this will be done opportunistically over |
|
time as we generalize parts of the API to be less client-specific. |
|
|
|
# Mailing list and meetings |
|
|
|
We have an open mailing list [xds-wg@lists.cncf.io](https://lists.cncf.io/g/xds-wg/) for communication and announcements. We also meet |
|
on an ad hoc basis via Zoom. |
