AppleTalk

An Apple Macintosh network protocol, based on the OSI Reference Model, which gives every Macintosh networking capabilities. AppleTalk can run under several network operating systems, including Apple Computer's AppleShare, Novell NetWare for the Macintosh, and TOPS from Sun Microsystems.

AppleTalk includes specifications for the data-link layer as LocalTalk, EtherTalk, FDDI-Talk, or TokenTalk, and the network layer as Datagram Delivery Protocol. The transport layer contains four protocols:

• Routing Table Maintenance Protocol (RTMP)
• AppleTalk Echo Protocol (AEP)
• AppleTalk Transaction Protocol (ATP)
• Name Binding Protocol (NBP)

The session layer includes

• AppleTalk Data Stream Protocol (ADSP)
• AppleTalk Session Protocol (ASP)
• Printer Access Protocol (PAP)
• Zone Information Protocol (ZIP)

The presentation layer adds the AppleTalk Filing Protocol (AFP) for access to remote files on shared disks.
