- MIT's 802.11b/g/n enterprise wireless network (showing MIT SECURE, MIT, and MIT GUEST SSIDs)
Several consumer iPhone/iPod Touch/iPad applications from Apple rely on Bonjour, an implementation of the ZEROCONF protocol for automatically discovering devices on a home or small business network, to connect to each other or other network devices. Currently these applications and services include:
- Remote (iPod Touch, iPhone, iPad)
Used to remotely control iTunes on your Mac from your iPhone
- Keynote Remote (iPod Touch, iPhone, iPad)
Used to remotely control Keynote on your Mac from your iPhone
Used to stream music or video from or to a portable device
Used to print to special AirPrint-enabled printers
While ZEROCONF and Bonjour work well on home or small business networks, they are not compatible with large enterprise networks which can frequently have thousands of devices in the same wireless address space. ZEROCONF relies on multicast traffic to discover devices on the network, which exhibits crippling performance and load issues on large enterprise network implementations. Even if it were enabled on the network, results would be slow to return and potentially return lists of hundreds of devices to choose from, which can be unmanageable on devices such as iPhones or iPads.
MIT will continue to explore possible work-arounds to allow community members to use consumer technologies such as Bonjour, AirPrint, and AirPlay in campus locations, but at the moment these and other consumer technologies relying solely on Bonjour and multicast will not work on the MIT enterprise wireless networks.
