In the original specification, XMPP could use HTTP in two ways: polling and binding. As an alternative to the TCP transport, the XMPP community has also developed an HTTP transport for web clients as well as users behind restricted firewalls. The original and "native" transport protocol for XMPP is Transmission Control Protocol (TCP), using open-ended XML streams over long-lived TCP connections. The means to route messages based on a logical endpoint identifier - the JID, instead of by an explicit IP Address present opportunities to use XMPP as an Overlay network implementation on top of different underlay networks. A resource remains optional for these JIDs as well. JIDs without a username part are also valid, and may be used for system messages and control of special features on the server. The highest priority is the one with largest numerical value. Messages simply sent to will go to the client with highest priority, but those sent to will go only to the mobile client.

For example, the full JID of a user's mobile account could be resource may have specified a numerical value called priority. This may be included in the JID by appending a slash followed by the name of the resource. A resource identifies a particular client belonging to the user (for example home, work, or mobile). Since a user may wish to log in from multiple locations, they may specify a resource. The JID is structured like an email address with a username and a domain name (or IP address ) for the server where that user resides, separated by an at sign ( - for example, “ here alice is the username and the server with which the user is registered. Internet protocol suiteĮvery user on the network has a unique XMPP address, called JID (for historical reasons, XMPP addresses are often called Jabber IDs).

Various XMPP client software are available on both desktop and mobile platforms and devices - by 2003 the protocol was used by over ten million people worldwide on the network, according to the XMPP Standards Foundation. Originally developed by the open-source community, the protocols were formalized as an approved instant messaging standard in 2004 and have been continuously developed with new extensions and features.
Numerous freeware and commercial software implementations also exist.

XMPP implementations can be developed using any software license and many server, client, and library implementations are distributed as free and open-source software.
This federated open system approach allows users to interoperate with others on any server using a 'JID' user account, similar to an email address. The architecture of the XMPP network is similar to email anyone can run their own XMPP server and there is no central master server. Unlike most commercial instant messaging protocols, XMPP is defined in an open standard in the application layer. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses. Based on XML (Extensible Markup Language), it enables the near-real-time exchange of structured data between two or more network entities. Not to be confused with XAMPP, a web server software stack, or Extreme Memory Profile (XMP), a memory overclocking standard.Įxtensible Messaging and Presence Protocol ( XMPP, originally named Jabber ) is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance.
