Multicast DNS and Bonjour® Services
Bonjour is the trade name for the zero configuration implementation introduced by Apple. It is supported by most of
the Apple product lines, including the Mac OS X operating system, iPhone, iPod Touch, iPad, Apple TV, and AirPort
Express. Apple AirPlay and AirPrint services are based on the Bonjour protocol and are essential services in
campus Wi-Fi networks.
Bonjour can be installed on computers running Microsoft Windows® and is supported by the new network-capable
printers. Bonjour is also included with popular software programs such as Apple iTunes, Safari, and iPhoto. Bonjour
uses multicast DNS (mDNS) to locate devices and the services offered by these devices.
As shown in the following figure, the IAP1 discovers AirPrint (P1) and IAP3 discovers Apple TV (TV1). IAP1
advertises information about its connected P1 device to the other IAPs that isIAP2 and IAP3. Similarly, IAP3
advertises TV1 device to IAP1 and IAP2. This type of distributed architecture allows any IAP to respond to its
connected devices locally. In this example, the iPad connected to IAP2 obtains direct response from the same IAP
about the other Bonjour-enabled services in the network.
