Xmpp stands for Extensible Messaging and Presence Protocol. It was earlier known as the 'Jabber'. The main purpose of xmpp is to provide extensible instant messaging (IM). It is also used for contact list maintenance and presence information. Although it was not originally present, xmpp has been extended to support new features such as Voice Over Internet and File transfer. When compared to other IM protocols, the specialty in xmpp is that it is an open systems protocol. This means that one xmpp service can be incorporated with other organizations' services. Both the software and most other additional applications are available for free download.

Xmpp uses a decentralized ragnarok server approach. This means that any person can implement and maintain their xmpp server; there is no central server controlling the whole network. There are many security features implemented in xmpp. Xmpp servers can be isolated from the public network. This is useful for running an intranet service. Tough security specifications have been built into the xmpp software. Client-server approach is used in xmpp to facilitate communication. In this approach, any two clients will not be able to communicate directly with each other, but will have to communicate through a server. However, unlike some chat services, there is no centralized server controlling all communications.
