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

AirGroup when the VLANs of the devices are terminated on the Virtual Controller.

AirGroup also supports ClearPass Policy Manager (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 isOAW-IAP2

and OAW-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.
