XMPP的前身是Jabber，一个开源形式组织产生的网络即时通信协议。XMPP目前被IETF国际标准组织完成了标准化工作。标准化的核心结果分为两部分；

核心的XML流传输协议

基于XML流传输的即时通讯扩展应用

XMPP的核心XML流传输协议的定义使得XMPP能够在一个比以往网络通信协议更规范的平台上。借助于XML易于解析和阅读的特性，使得XMPP的协议能够非常漂亮。

XMPP的即时通讯扩展应用部分是根据IETF在这之前对即时通讯的一个抽象定义的，与其他业已得到广泛使用的即时通讯协议，诸如AIM，QQ等有功能完整，完善等先进性。-XMPP is the predecessor of Jabber, an open source network forms of organizations real-time communication protocol. XMPP is being ISO IETF standardization work has been completed. The results of the standardization of the core is divided into two parts　

The core XML streaming protocol

　　　XML-based streaming real-time communications applications to expand

　　 XMPP s core XML streaming protocol allows the definition of XMPP to the network than ever before in a more standardized communication protocol platform. Through the use of XML parsing and easy to read features, the XMPP makes a very good agreement.

XMPP instant messaging application part of the expansion is based on IETF in this real-time communications prior to the definition of an abstract, and has been widely used in other real-time communication protocols, such as AIM, QQ, such as functional integrity and perfect nature.
