## Architecture
|
|
|
|
|
|
SRS always use the most simple architecture to support complex transaction.
|
|
|
* System arch: the system structure and arch.
|
|
|
* Modularity arch: the main modularity of SRS.
|
|
|
* Stream arch: the stream dispatch arch of SRS.
|
|
|
* RTMP cluster arch: the RTMP origin and edge cluster arch.
|
|
|
* Multiple processes arch (by wenjie): the multiple process of SRS.
|
|
|
* CLI arch: the cli arch for SRS, api to manage SRS.
|
|
|
* Bandwidth specification: the bandwidth test specification of SRS.

Remark:
|
|
|
(1) Encoder: encoder must push RTMP stream to SRS server.
|
|
|
(2) MediaSource: any media source, which can be ingest by ffmpeg.
|
|
|
(3) Ingester: SRS will fork a process to run ffmpeg(or your application)
|
|
|
to ingest any input to rtmp, push to SRS.

Schema#1: Any RTMP encoder push RTMP stream to RTMP (origin/edge)server,
|
|
|
where SRS RTMP Edge server will forward stream to origin.

Schema#2: SRS RTMP Edge server pull stream from origin (or upstream SRS
|
|
|
RTMP Edge server), then delivery to Client.
