Faye is a publish-subscribe messaging system based on Thebayeux protocol/cometd. IT provides message servers fornode. js and Ruby, and clients for use with the server and in all major web Browsers.

System architecture

Component	Function
Storage	storage content active client ID subscription information queued message to BES delivered to clients storage mode memory engine redis engine
engine	storage the abstraction layer, realizing all the services of Faye client registering Span style= "font-size:12pt" > storing subscriptions Span style= "font-size:14pt" >routing messages
server	implements Bayeus protocol, operation set handshake connect disconnect subscribe unsubscribe publish server no HTTP or any other network transmission technology related
Server-side extendsions	Extension layer, can intercept incoming/outgoing message
Adapter	provides server services over HTTP, responsible for JSON serialization and deserialization message;< Span style= "font-family: Arial" > connection processing persistent connection based on WebSocket HTTP post-based long polling CORS (Cross Origin Resource sharing) JSONP Two implementations: Nodeadapter, Rackadapter
transport	client's network transport, Responsible for serialization and deserialization of communications and JSON as well as detection and recovery of network faults WebSocket Real-time strong long Polling/ Jsonp can only rely on timeouts
client-side extensions	similar to server-side extendsions
Client	Provide subscribe/unsubscribe, Send/receive message Interface, implement Bayeux protocol, users do not need to deal with handshake and connect and other underlying operations

Cluster support

The storage in this structure uses Redis. The server is stateless, facilitates horizontal scaling, and simplifies routing (using a random/RR strategy).

Easy to use

Use similar socket.io.
