[Bonjour](http://www.apple.com/macosx/technology/bonjour.html), formerly

Rendezvous, is Apple Inc.'s trade name for its implementation of Zeroconf, a

service discovery protocol used in Apple's Mac OS X operating system from

version 10.2 onwards. Intended for use on local area networks, Bonjour uses

multicast Domain Name System service records to locate devices such as

printers, as well as other computers, and the services that those devices

offer.

The [XMPP Standards Foundation](http://www.xmpp.org/) worked with developers at

Apple and several open-source projects to generate complete documentation of

Bonjour messaging. The relevant specification is

[XEP-0174: Link-Local Messaging](http://www.xmpp.org/extensions/xep-0174.html).
