The method is the most popular communication mode on the current network, and various instant communication software also comes out endlessly; service providers are also offering increasingly rich communication service features.
The currently widely adopted technology introduces a platform integrating a third party, wherein the third platform is based on an xmpp protocol, and the xmpp is based on xml, and defines three roles, namely a client, a server and a gateway. Communication can occur bi-directionally between any two of the three. The server simultaneously bears the functions of client information recording, connection management and information routing, the gateway bears the intercommunication and interconnection with the heterogeneous instant messaging system, and the basic network form is that a single client is connected to a single server through TCP/IP and xml is transmitted between the single client and the single server.
