The other type of communication is messaging. This can be used to create applications that push messages from the server and perform near real time communication.
RTMP的一个主要好处是可以一直打开与客户端的连接，这样就可以推送服务器端的数据了。
One of the primary benefits of RTMP is the connection with the client stays open so it can be used to push data from the server.
