Extensible Messaging and

Presence Protocol (XMPP)

Extensible Messaging and Presence Protocol

(XMPP) is a communications protocol for

message-oriented middleware based on XML(Extensible Markup Language)

The protocol was originally named Jabber,

and was developed by the Jabber open-

source community in 1999 for near real-time,instant messaging (IM), presence information,

and contact list maintenance.

Extensible Messaging and

Presence Protocol (XMPP) In August 2005, Google introduced Google Talk, a

combination VoIP and IM system that uses XMPP for

instant messaging and as a base for a voice and file

transfer signaling protocol called Jingle In January 2008, AOL introduced experimental

Extensible Messaging and Presence Protocol (XMPP)

support for its AOL Instant Messenger (AIM) service.

In February 2010, the social-networking site Facebook

opened up its chat feature to third-party applicationsvia XMPP, but some server-side features like roster

editing cannot be done via XMPP.

XMPP - Strengths

Decentralization

Open standards (the latest specifications are RFC 6120and RFC 6121)) no royalty

History

Security can be isolated from public XMPP networkvia SASL dan TLS

Flexibility

groupchat, network management, content syndication,collaboration tools, file sharing, gaming, remotesystems control and monitoring, geolocation,middleware and cloud computing, VoIP and Identityservices.

XMPP - Weaknesses

In-band binary data transfer is inefficient

Binary data must be first base64 encoded before it

can be transmitted in-band.

Therefore any significant amount of binary data

(e.g., file transfers) is best transmitted out-of-band,

using in-band messages to coordinate.

The best example of this is the Jingle XMPP Extension

Protocol, XEP-0166

XMPP - Decentralization and

addressing

Every user on the network has a unique Jabber

ID (usually abbreviated as JID). Like an email

address with a username and a domain name (orIP address), separated by an at sign (@), such as

[email protected].

Since a user may wish to log in from multiple

locations, they may specify a resource. Forexample, the full JID of a user's mobile account

would be [email protected]/mobile.

JID without a username part are also valid, and

may be used for system
