The AppleTalk* and AppleTalk-related suite of protocols is described in the following table.
AARP |
AppleTalk Address Resolution Protocol. An AppleTalk protocol that reconciles addressing differences between a data link protocol and the rest of a protocol family. For example, by resolving the differences between an Ethernet addressing scheme and the AppleTalk addressing scheme, AARP facilitates the transport of datagram delivery protocol (DDP) packets over a high-speed EtherTalk* connection. |
ADSP |
AppleTalk Data Stream Protocol. A connection-oriented protocol that provides a reliable, full-duplex, byte stream service between any two sockets in an AppleTalk internetwork. ADSP ensures sequential, duplicate-free delivery of data over its connections. |
AEP |
AppleTalk Echo Protocol. A simple protocol that allows a node to send a packet to any other node in an AppleTalk internetwork and receive an echoed copy of that packet in return. |
AFP |
AppleTalk Filing Protocol. A presentation layer protocol that allows users to share data files and applications that reside in an AppleTalk shared resource, such as a file server. |
ASP |
AppleTalk Session Protocol. A general, all-purpose protocol that uses the services of the AppleTalk Transaction Protocol (ATP) to provide session establishment, maintenance, and tear-down, along with request sequencing. |
ATP |
AppleTalk Transaction Protocol. A transport protocol that provides a loss-free transaction service between sockets. This service allows exchanges between two socket clients in which one client requests the other to perform a particular task and report the results. ATP binds the request and response together to ensure the reliable exchange of request-response pairs. |
E-DDP |
Extended Datagram Delivery Protocol. A datagram delivery protocol that uses an extended header. An extended header is required for packets that are transmitted from one network to another network within an AppleTalk Internet. |
ELAP |
EtherTalk Link Access Protocol. The link-access protocol used in an EtherTalk network. It is built on the top of the standard Ethernet data link layer. |
NBP |
Name Binding Protocol. A transport layer protocol that translates a character string name into the internetwork address of the corresponding socket client. NBP enables AppleTalk protocols to understand user-defined zones and device names by providing and maintaining translation tables that map these names to corresponding socket addresses. |
PAP |
Printer Access Protocol. This protocol manages interaction between workstations and print servers. It handles connection setup, maintenance, and termination. It can also handle data transfer. |
RTMP |
Routing Table Maintenance Protocol. This AppleTalk protocol establishes and maintains the routing information that is required by internetwork routers to route datagrams from any source socket to any destination socket in the internetwork. Using RTMP, internetwork routers dynamically maintain routing tables to reflect changes in internetwork topology. |
S-DDP |
Short Datagram Delivery Protocol. A DDP that uses a short header. A short header is often used for packets whose source and destination sockets are within the boundaries of a single AppleTalk network. |
ZIP |
Zone Information Protocol. A protocol that maintains up-to-date routing information across the internetwork. |
