 # OriginCluster
 
-## Design
+The SRS origin cluster is a group of origin servers intended for handling a large number of streams.
+
+The new origin cluster is designed as a collection of proxy servers. For more information, see
+[Discussion #3634](https://github.com/ossrs/srs/discussions/3634). If you prefer to use the old
+origin cluster, please switch to a version before SRS 6.0.
+
+## Introduction
+
+You can deploy multiple SRS origin servers, to handle a large number of streams. The proxy server is
+used as a load balancer for these origin servers:
+
+```text
+                                       +--------------------+
+                               +-------+ SRS Origin Server  +
+                               +       +--------------------+
+                               +
++-----------------------+      +       +--------------------+
++ SRS Proxy(Deployment) +------+-------+ SRS Origin Server  +
++-----------------------+      +       +--------------------+
+                               +
+                               +       +--------------------+
+                               +-------+ SRS Origin Server  +
+                                       +--------------------+
+```
+
+The origin cluster also enhances the scalability of the origin server. For instance, with 200 backend 
+SRS origin servers, it can support 100 WebRTC streamers, each with 200 viewers, totaling 20,000 connections.
+If you deploy this cluster on a server with a large number of CPU cores, it becomes a very powerful 
+media server.
+
+> Note: You are also able to deploy multiple proxy servers, or proxy to other media servers, or work 
+> with edge cluster, see [Design](#design) for details.
+
+The proxy server support almost all protocols of SRS, including RTMP, HTTP-FLV, HLS, WebRTC, and SRT. 
+Please see [Protocols](#protocols) for details.
+
+## Build
+
+To build the proxy server, you need to have Go 1.18+ installed. Then, you can build the proxy 
+server by:
+
+```bash
+cd srs/proxy && make
+```
+
+> Note: You can also download the dependencies by running `go mod download` before building.
+
+We will support the Docker image in the future, or integrate the proxy server into the Oryx 
+project.
+
+## RTMP Origin Cluster
+
+To use the RTMP origin cluster, you need to deploy the proxy server and the origin server. 
+First, start the proxy server:
+
+```bash
+env PROXY_RTMP_SERVER=1935 PROXY_HTTP_SERVER=8080 \
+    PROXY_HTTP_API=1985 PROXY_WEBRTC_SERVER=8000 PROXY_SRT_SERVER=10080 \
+    PROXY_SYSTEM_API=12025 PROXY_LOAD_BALANCER_TYPE=memory ./srs-proxy
+```
+
+> Note: Here we use the memory load balancer, you can switch to `redis` if you want to run more
+> than one proxy server.
+
+Then, deploy three origin servers, which connects to the proxy server via port `12025`:
+
+```bash
+./objs/srs -c conf/origin1-for-proxy.conf
+./objs/srs -c conf/origin2-for-proxy.conf
+./objs/srs -c conf/origin3-for-proxy.conf
+```
+
+> Note: The origin servers are independent, so it's recommended to deploy them as Deployments 
+> in Kubernetes (K8s).
+
+Now, you're able to publish RTMP stream to the proxy server:
+
+```bash
+ffmpeg -re -i doc/source.flv -c copy -f flv rtmp://localhost/live/livestream
+```
+
+And play the RTMP stream from the proxy server:
+
+```bash
+ffplay rtmp://localhost/live/livestream
+```
+
+Or play HTTP-FLV stream from the proxy server:
+
+```bash
+ffplay http://localhost:8080/live/livestream.flv
+```
+
+Or play HLS stream from the proxy server:
+
+```bash
+ffplay http://localhost:8080/live/livestream.m3u8
+``` 
+
+Or play the WebRTC stream via [WHEP player](http://localhost:8080/players/whep.html) from proxy server.
+
+You can also use VLC or other players to play the stream in proxy server.
+
+## WebRTC Origin Cluster
+
+To use the WebRTC origin cluster, you need to deploy the proxy server and the origin server.
+First, start the proxy server:
+
+```bash
+env PROXY_RTMP_SERVER=1935 PROXY_HTTP_SERVER=8080 \
+    PROXY_HTTP_API=1985 PROXY_WEBRTC_SERVER=8000 PROXY_SRT_SERVER=10080 \
+    PROXY_SYSTEM_API=12025 PROXY_LOAD_BALANCER_TYPE=memory ./srs-proxy
+```
+
+> Note: Here we use the memory load balancer, you can switch to `redis` if you want to run more
+> than one proxy server.
+
+Then, deploy three origin servers, which connects to the proxy server via port `12025`:
+
+```bash
+./objs/srs -c conf/origin1-for-proxy.conf
+./objs/srs -c conf/origin2-for-proxy.conf
+./objs/srs -c conf/origin3-for-proxy.conf
+```
+
+> Note: The origin servers are independent, so it's recommended to deploy them as Deployments
+> in Kubernetes (K8s).
+
+Now, you're able to publish WebRTC stream via [WHIP player](http://localhost:8080/players/whip.html) to the proxy server.
+
+And play the WebRTC stream via [WHEP player](http://localhost:8080/players/whep.html) from proxy server.
+
+Or play the RTMP stream from the proxy server:
+
+```bash
+ffplay rtmp://localhost/live/livestream
+```
+
+Or play HTTP-FLV stream from the proxy server:
+
+```bash
+ffplay http://localhost:8080/live/livestream.flv
+```
+
+Or play HLS stream from the proxy server:
+
+```bash
+ffplay http://localhost:8080/live/livestream.m3u8
+```
+
+You can also use VLC or other players to play the stream in proxy server.
+
+## SRT Origin Cluster
+
+To use the SRT origin cluster, you need to deploy the proxy server and the origin server.
+First, start the proxy server:
+
+```bash
+env PROXY_RTMP_SERVER=1935 PROXY_HTTP_SERVER=8080 \
+    PROXY_HTTP_API=1985 PROXY_WEBRTC_SERVER=8000 PROXY_SRT_SERVER=10080 \
+    PROXY_SYSTEM_API=12025 PROXY_LOAD_BALANCER_TYPE=memory ./srs-proxy
+```
+
+> Note: Here we use the memory load balancer, you can switch to `redis` if you want to run more
+> than one proxy server.
+
+Then, deploy three origin servers, which connects to the proxy server via port `12025`:
+
+```bash
+./objs/srs -c conf/origin1-for-proxy.conf
+./objs/srs -c conf/origin2-for-proxy.conf
+./objs/srs -c conf/origin3-for-proxy.conf
+```
+
+> Note: The origin servers are independent, so it's recommended to deploy them as Deployments
+> in Kubernetes (K8s).
+
+Now, you're able to publish SRT stream to the proxy server:
+
+```bash
+ffmpeg -re -i ./doc/source.flv -c copy -pes_payload_size 0 -f mpegts \
+  'srt://127.0.0.1:10080?streamid=#!::r=live/livestream,m=publish'
+```
 
-About the design of Origin Cluster, please read the [Issue#464](https://github.com/ossrs/srs/issues/464#issuecomment-306082751).
-SRS Origin Cluster is designed for large amount of streams.
+And play the SRT stream from the proxy server:
 
-![](/img/doc-advanced-guides-origin-cluster-001.png)
+```bash
+ffplay 'srt://127.0.0.1:10080?streamid=#!::r=live/livestream,m=request'
+```
+
+Or play the RTMP stream from the proxy server:
+
+```bash
+ffplay rtmp://localhost/live/livestream
+```
+
+Or play HTTP-FLV stream from the proxy server:
+
+```bash
+ffplay http://localhost:8080/live/livestream.flv
+```
 
-> Remark: Origin cluster only supports RTMP, use Edge to transmux RTMP to FLV.
+Or play HLS stream from the proxy server:
+
+```bash
+ffplay http://localhost:8080/live/livestream.m3u8
+``` 
+
+Or play the WebRTC stream via [WHEP player](http://localhost:8080/players/whep.html) from proxy server.
+
+You can also use VLC or other players to play the stream in proxy server.
 
 ## Config
 
-The config for origin cluster:
+The proxy server is configured by environment variables. The supported environment variables for proxy
+backend server are:
+
+* `PROXY_HTTP_API`: The HTTP API port, proxy to SRS origin server. Default: `11985`
+* `PROXY_HTTP_SERVER`: The HTTP streaming server, proxy to SRS origin server. Default: `18080`
+* `PROXY_RTMP_SERVER`: The RTMP server, proxy to SRS origin server. Default: `11935`
+* `PROXY_WEBRTC_SERVER`: The WebRTC server, proxy to SRS origin server, via UDP protocol. Default: `18000`
+* `PROXY_SRT_SERVER`: The SRT server, proxy to SRS origin server. Default: `20080`
+
+The following environment variables are about the proxy server itself:
+
+* `PROXY_SYSTEM_API`: The system API port, allow origin server register services to proxy servers. Default: `12025`
+* `PROXY_STATIC_FILES`: The files directory for static web server, like the players. Default: `../trunk/research`
+* `PROXY_LOAD_BALANCER_TYPE`: The load balancer type, `memory` or `redis`. Default: `redis`
+
+For the Redis load balancer, you need to set the following environment variables:
 
+* `PROXY_REDIS_HOST`: The Redis host. Default: `127.0.0.1`
+* `PROXY_REDIS_PORT`: The Redis port. Default: `6379`
+* `PROXY_REDIS_PASSWORD`: The Redis password. Default to empty, no password.
+* `PROXY_REDIS_DB`: The Redis DB. Default: `0`
+
+For debugging, the proxy server will proxy to a default origin server, you can set the following
+environment variables:
+
+* `PROXY_DEFAULT_BACKEND_ENABLED`: Whether to enable the default backend origin server. Default: `off`
+* `PROXY_DEFAULT_BACKEND_IP`: The default backend IP. Default: `127.0.0.1`
+* `PROXY_DEFAULT_BACKEND_RTMP`: The default backend RTMP port. Default: `1935`
+* `PROXY_DEFAULT_BACKEND_HTTP`: The default backend HTTP port. Default: `8080`
+* `PROXY_DEFAULT_BACKEND_RTC`: The default backend WebRTC port via UDP. Default: `8000`
+* `PROXY_DEFAULT_BACKEND_SRT`: The default backend SRT port. Default: `10080`
+* `PROXY_DEFAULT_BACKEND_API`: The default backend API port. Default: `1985`
+
+> Note: The default backend origin server, is designed for any RTMP server like nginx-rtmp, it does not
+> require the origin server to register to the proxy server.
+
+## Design
+
+The proxy works with SRS origin servers, and the stream flow operates as follows:
+
+```text
+Client ----> Proxy Server ---> Origin Servers
+Client ---> LB --> Proxy Servers --> Origin Servers
+
+OBS/FFmpeg --RTMP--> K8s(Service) --Proxy--> SRS(pod A)
+
+Browsers --FLV/HLS/SRT--> K8s(Service) --Proxy--> SRS(pod A)
+
+Browsers --+---HTTP-API--> K8s(Service) --Proxy--> SRS(pod A)
+           +---WebRTC----> K8s(Service) --Proxy--> SRS(pod A)
+```
+
+> Note: This proxy server can be deployed in Kubernetes (K8s) and can route traffic to the SRS origin
+> servers. The proxy server functions as a load balancer to distribute the load among the origin servers.
+> You can also use the proxy server without Kubernetes.
+
+This is the detailed deployment process that works with the Kubernetes (K8s) system:
+
+```text
+                         +-----------------------+
+                     +---+ SRS Proxy(Deployment) +------+---------------------+
++-----------------+  |   +-----------+-----------+      +                     +
+| LB(K8s Service) +--+               +(Redis/MESH)      + SRS Origin Servers  +
++-----------------+  |   +-----------+-----------+      +    (Deployment)     +
+                     +---+ SRS Proxy(Deployment) +------+---------------------+

 ```
 
-* mode: The mode of cluster, it should be local for origin cluster.
-* origin_cluster: Whether enable origin cluster.
-* coworkers: The HTTP APIs of other origin servers in the cluster. 
+> Note: With this architecture, you can build a very large media system that supports a large number of
+> streams and viewers. It is a complex system to maintain, so only use it if necessary.
 
-> Remark: Say, a client, a player or edge server, starts to play a stream from a origin server. The origin server would query the coworkers and redirect client by RTMP302 when it doesn't serve the stream. If no origin is found, it responses error. The HTTP API response message includes fields for whether owns the stream, and stream information. 
+In fact, a proxy server also works with SRS edge servers, but it is not a typical architecture.
 
-> Remark: Note in particular that server response error when the requested stream hasn't been publish to origin server. For independent origin server, server responses success and waits for stream to be published. While when origin in origin cluster, as the stream might not be published to it, it should responses error and shouldn't wait for the stream.
+## Protocols
 
-## Usage
+Because the proxy server is a new server, not all protocols are supported yet. The supported
+protocols are:
 
-To use origin cluster, please read [#464](https://github.com/ossrs/srs/issues/464#issuecomment-366169487).
+- [x] RTMP: Proxy RTMP protocol to the SRS origin server.
+- [x] HTTP-FLV: Proxy HTTP-FLV protocol to the SRS origin server.
+- [x] HTTP-TS: Proxy HTTP-TS protocol to the SRS origin server.
+- [x] HLS: Proxy HLS protocol to the SRS origin server.
+- [x] WebRTC: Proxy WebRTC(WHIP/WHEP) protocol to the SRS origin server.
+- [x] SRT: Proxy SRT protocol to the SRS origin server.
+- [ ] MPEG-DASH: Proxy MPEG-DASH protocol to the SRS origin server.
+- [ ] RTSP: Proxy RTSP protocol to the SRS origin server.
+
+There are also some key features not supported yet:
+
+- [x] Single node proxy server, use memory to store state.
+- [x] Redis: Connect to the Redis server to sync the state.
+- [ ] MESH: Connect to other proxy servers to sync the state.
+- [ ] HTTP-API: Provide an HTTP API that collects all the metrics of the origin servers.
+- [ ] Exporter: Provide a Prometheus exporter that exports the metrics of the proxy server.
+
+For a media cluster, the media server is only one part of the whole system. The control and management panel
+are also very important to maintain this complex system.
+
+## Register
+
+The origin server can register itself to the proxy server, so the proxy server can load balance 
+the backend servers. The register API is a simple HTTP API:
+
+```bash
+curl -X POST http://127.0.0.1:12025/api/v1/srs/register \
+     -H "Connection: Close" \
+     -H "Content-Type: application/json" \
+     -H "User-Agent: curl" \
+     -d '{
+          "device_id": "origin2",
+          "ip": "10.78.122.184",
+          "server": "vid-46p14mm",
+          "service": "z2s3w865",
+          "pid": "42583",
+          "rtmp": ["19352"],
+          "http": ["8082"],
+          "api": ["19853"],
+          "srt": ["10082"],
+          "rtc": ["8001"]
+        }'
+#{"code":0,"pid":"53783"}
+```
 
-We also recommend to use a edge server please read [here](https://github.com/ossrs/srs/issues/464#issuecomment-366169962). The edge server can transmux RTMP to HTTP-FLV, supports fault-tolerance.
+* `ip`: Mandatory, the IP of the backend server. Make sure the proxy server can access the backend server via this IP.
+* `server`: Mandatory, the server id of backend server. For SRS, it stores in file, may not change.
+* `service`: Mandatory, the service id of backend server. For SRS, it always changes when restarted.
+* `pid`: Mandatory, the process id of backend server. Used to identify whether process restarted.
+* `rtmp`: Mandatory, the RTMP listen endpoints of backend server. Proxy server will connect backend server via this port for RTMP protocol.
+* `http`: Optional, the HTTP listen endpoints of backend server. Proxy server will connect backend server via this port for HTTP-FLV or HTTP-TS protocol.
+* `api`: Optional, the HTTP API listen endpoints of backend server. Proxy server will connect backend server via this port for HTTP-API, such as WHIP and WHEP.
+* `srt`: Optional, the SRT listen endpoints of backend server. Proxy server will connect backend server via this port for SRT protocol.
+* `rtc`: Optional, the WebRTC listen endpoints of backend server. Proxy server will connect backend server via this port for WebRTC protocol.
+* `device_id`: Optional, the device id of backend server. Used as a label for the backend server.
 
-2018.02
+You can also use SRS 5.0+ as backend server, which supports `heartbeat` feature to register itself 
+to proxy server.
 
-![](https://ossrs.io/gif/v1/sls.gif?site=ossrs.io&path=/lts/doc/en/v6/origin-cluster)
+Furthermore, you can write a curl script to register the backend server, or a dedicate backend server 
+manage service. For example, if you don't want to modify the nginx-rtmp code, you can use a isolate program 
+to register the nginx-rtmp to proxy server.

 # OriginCluster
 
-## Design
+SRS源站集群是一组源站服务器，用于大量流的场景。
 
-关于源站集群的设计参考[Issue#464](https://github.com/ossrs/srs/issues/464#issuecomment-306082751)。
-源站集群主要解决大量推流的情况，比如需要推1万路流。
+新的源站集群被设计为一组代理服务器，详情请参考[Discussion #3634](https://github.com/ossrs/srs/discussions/3634)。
+如果您想使用旧的源站集群，请切换到SRS 6.0之前的版本。
 
-![](/img/doc-advanced-guides-origin-cluster-001.png)
-
-> Remark: 源站集群只支持RTMP协议，如果需要HTTP-FLV，可以加一个Edge将RTMP转成HTTP-FLV。
-
-## Config
-
-源站集群的配置如下：
-
-```
-vhost __defaultVhost__ {
-    # The config for cluster.
-    cluster {
-        # The cluster mode, local or remote.
-        #       local: It's an origin server, serve streams itself.
-        #       remote: It's an edge server, fetch or push stream to origin server.
-        # default: local
-        mode            local;
-
-        # For origin(mode local) cluster, turn on the cluster.
-        # @remark Origin cluster only supports RTMP, use Edge to transmux RTMP to FLV.
-        # default: off
-        # TODO: FIXME: Support reload.
-        origin_cluster      on;
-
-        # For origin (mode local) cluster, the co-worker's HTTP APIs.
-        # This origin will connect to co-workers and communicate with them.
-        # please read: https://ossrs.net/lts/zh-cn/docs/v4/doc/origin-cluster
-        # TODO: FIXME: Support reload.
-        coworkers           127.0.0.1:9091 127.0.0.1:9092;
-    }
-}
-```
-
-其中：
-
-* mode: 集群的模式，对于源站集群，值应该是local。
-* origin_cluster: 是否开启源站集群。
-* coworkers: 源站集群中的其他源站的HTTP API地址。
-
-> Remark: 如果流不在本源站，会通过HTTP API查询其他源站是否有流。如果流其他源站，则返回RTMP302重定向请求到该源站。如果所有源站都没有流则返回错误。
-
-> Remark: 特别注意的是，如果流还没有开始推，那么服务器会返回失败，这点和源站没有在源站集群的行为不同。当源站独立工作时，会等待流推上来；当源站在源站集群中时，因为流可能不会推到本源站，所以等待流推上来没有意义。
-
-## Usage
-
-源站集群的用法参考[#464](https://github.com/ossrs/srs/issues/464#issuecomment-366169487)。
-
-推荐在源站集群前面挂一系列的Edge服务器，参考[这里](https://github.com/ossrs/srs/issues/464#issuecomment-366169962)，Edge服务器可以转换协议，支持RTMP和HTTP-FLV，同时支持源站故障时自动切换，不中断客户端。
