![A simple XMPP network with the servers jabber.org and draugr.de. Green clients are online, yellow clients are writing each other and small green subclients are the resources of one user. The brown network is not connected to the internet. The server draugr.de is connected to other IM services (ICQ, AIM and other) via XMPP transports.](/Images/godic/202502/21/JabberNetwork.svg4920.png")

Extensible Messaging and Presence Protocol (XMPP) is a communications protocol for message-oriented middleware based on XML (Extensible Markup Language). It enables the near-real-time exchange of structured yet extensible data between any two or more network entities. Originally named Jabber, the protocol was developed by the Jabber open-source community in 1999 for near real-time instant messaging (IM), presence information, and contact list maintenance. Designed to be extensible, the protocol has been used also for publish-subscribe systems, signalling for VoIP, video, file transfer, gaming, Internet of Things (IoT) applications such as the smart grid, and social networking services.
