  • 2. Application & presentation AFP: (apple filing protocol). The AppleTalk Filing Protocol (AFP) is the file sharing protocol of the AppleTalk architecture. It provides a native mode interface to Apple file system resources. Apple files are comprised of two data structures called forks. An Apple file may be accessed by its data fork or its resource fork. The data fork holds raw file data while the resource fork contains information used by the operating system to manage icons and drivers.
  • 3. ASP The AppleTalk Session Protocol (ASP) manages sessions for higher layer protocols such as AFP. ASP issues a unique session identifier for each logical connection and continuously monitors the status of each connection. It maintains idle sessions by periodically exchanging keep alive frames in order to verify the session status. Zone Information Protocol ZIP was the protocol by which AppleTalk network numbers were associated with zone names. A zone was a subdivision of the network that made sense to humans (for example, "Accounting Department"); but while a network number had to be assigned to a topologically-contiguous section of the network, a zone could include several different discontiguous portions of the network.
  • 4. AppleTalk Transaction Protocol ATP was the original reliable transport-level protocol for AppleTalk, built on top of DDP. At the time it was being developed, a full, reliable connection-oriented protocol like TCP was considered to be too expensive to implement for most of the intended uses of AppleTalk. Thus, ATP was a simple request/response exchange, with no need to set up or tear down connections. AppleTalk Echo Protocol AEP (AppleTalk Echo Protocol) is a transport layer protocol designed to test the reachability of network nodes. AEP generates packets to be sent to the network node and is identified in the Type field of a packet as an AEP packet.
  • 5. Datagram Delivery Protocol : DDP was the lowest-level data-link-independent transport protocol.
  • 6. EtherTalk Link Access Protocol (ELAP) EtherTalk was developed by Apple as an extension of the Ethernet data link. The extension allows the use of an Ethernet data link and cabling in the AppleTalk network. LocalTalk Link Access Protocol (LLAP) This protocol manages the node-to-node transmission of data packets in the network. LLAP governs access to the link and provides a means for nodes to discover valid addresses. It does not guarantee packet delivery; it does guarantee that those packets that are delivered are error-free.
  • 7. Fiber Distributed Data Interface (FDDI) is a standard for data transmission in a local area network LocalTalk is a particular implementation of the physical layer of the AppleTalk networking sy stem from Apple Computer. LocalTalk specifies a system of shielded twisted pair cabling, plugged into self- terminating transceivers, running at a rate of 230.4 kbit/s. CSMA/CA was implemented as a random multiple access method.
