Abstract
While TCP/IP has emerged as undisputed winner for wide area networking,
with the dual "killer apps" of email and the web, local area
communications remain a confused mish-mash of technologies like serial
ports, parallel ports, SCSI, IrDA, USB, FireWire, Bluetooth, etc. Stuart
Cheshire speculated that since TCP/IP is such a clear success for wide
area networking, perhaps it could also be the solution for local area
communications too. With the work done at the IETF under the name
"Zeroconf", and at Apple under the name "Bonjour", Apple and other
companies have demonstrated that TCP/IP (running over Ethernet, 802.11
wireless, or any other suitable link-layer technology) can be as easy to
use and hassle-free as any of the dedicated local communication
technologies like USB. Bonjour/Zeroconf was not the world's first
attempt to make TCP/IP easy to use in the LAN environment, but it's the
only one to achieve widespread success in the marketplace. For example,
every network printer sold today from every major printer manufacturer
implements the Zeroconf protocols. Stuart Cheshire will describe the
three simple protocols that go together to create the Zero Configuration
trio, and will then show a sample of some of the many "cool toys" from
Apple and other companies that are built on this foundation. Apple may
have been one of the earliest adopters of the Zeroconf technologies, but
the specifications are open and multiple Open Source implementations
(including one from Apple) exist in a variety of different languages.
