AirGroup Overview
AirGroup is a unique enterprise-class capability that leverages zero configuration networking to enable Bonjour®
services such as Apple® AirPrint and AirPlay from mobile devices in an efficient manner. Apple AirPlay and AirPrint
services are based on the Bonjour protocol are essential services in campus Wi-Fi networks.
Zero configuration networking enables service discovery, address assignment, and name resolution for desktop
computers, mobile devices, and network services. It is designed for flat, single-subnet IP networks such as wireless
networking at home. 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.
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. The AirGroup solution
supports both wired and wireless devices. Wired devices, which support the Bonjour services are made part of the
AirGroup when the VLANs of the devices are terminated on the Virtual Controller.
AirGroup also supports Alcatel-LucentClearPass Policy Manager. With CPPM:
l Users can register their personal devices and define a group of users who can to share the registered devices.
l Administrators can register and manage an organization's shared devices such as printers and conference room
Apple TVs. An administrator can grant global access to each device, or restrict access according to the
username, role, or user location.
The distributed AirGroup architecture allows each OAW-IAP to handle Bonjour queries and responses individually
instead of overloading a Virtual Controller with these tasks. This results in a scalable AirGroup solution.
As shown in the following figure, the OAW-IAP1 discovers Air Printer (P1) and OAW-IAP3 discovers Apple TV
(TV1). OAW-IAP1 advertises information about its connected P1 device to the other OAW-IAPs that is OAW-IAP2
andOAW-IAP3. Similarly, OAW-IAP3 advertises TV1 device to OAW-IAP1 and OAW-IAP2. This type of distributed
architecture allows any OAW-IAP to respond to its connected devices locally. In this example, the iPad connected
to OAW-IAP2 obtains direct response from the same OAW-IAP about the other Bonjour-enabled services in the
network.
