XMPP (Extensible Message Processing Field Protocol) is an Extensible Markup Language (XML)-based protocol that is used for instant messaging (IM) and on-line on-site probing. It facilitates the quasi-immediate operation between servers. The agreement may finally allow Internet users to send instant messages to anyone else on the internet, even if their operating systems and browsers are different.XMPP's predecessor was Jabber, an open source form of o

small data transmission rate is higher, because there is no need to send and receive data confirmation, so UDP real-time better.Know the difference between TCP and UDP, it is not difficult to understand why the use of TCP transmission protocol MSN than UDP transmission file slow, but can not say that QQ communication is not safe, because the programmer can manually verify the data sent and received by UDP, For example, the sender of each packet number and then by the receiver to verify AH what,

Parsing XMPP protocol analysis and application XMPP is an XML-based protocol that inherits the flexible development in the XML environment. Therefore, XMPP-based applications are highly scalable. After the extension, XMPP can send extended information to meet user requirements, and create application processes such as
