(redirected from AppleTalk Transport Protocol)


(networking, protocol)
A proprietary local area network protocol developed by Apple Computer, Inc. for communication between Apple products (e.g. Macintosh) and other computers. This protocol is independent of the network layer on which it runs. Current implementations exist for Localtalk, a 235 kilobyte per second local area network and Ethertalk, a 10 megabyte per second local area network.


Apple's original local area network architecture for its Macintosh line. Introduced in 1985, AppleTalk supported Apple's proprietary LocalTalk access method as well as Ethernet and Token Ring. The AppleTalk network manager and the LocalTalk access method were built into all Macintoshes and LaserWriters. Support for AppleTalk was made available for PCs, VAXs and Unix workstations with products from Apple and third parties. A routable protocol patterned after the OSI model, Appletalk eventually gave way to TCP/IP. See AFP and TCP/IP.
