TokenTalk Link Access Protocol
TokenTalk Link Access Protocol (TLAP) is a term from computer science .
The TokenTalk Link Access Protocol , or TLAP for short , is a protocol for transmission between the nodes in a Token Ring network. The TokenTalk Link Access Protocol manages the access to the bus, offers an addressing scheme for the respective node and controls the data transmission and its reception. It also ensures the correct package length.
It is defined in RFC 1742 .
Under the name Link Access Protocols in to AppleTalk on the data link layer protocols used together.
The AppleTalk protocol stack
The AppleTalk protocols can be divided into several layers that form a protocol stack . The protocols can be classified in the ISO-OSI reference model as follows :
| OSI layer | AppleTalk protocol stack | ||||||
| 7th | AFP | PAP | |||||
| 6th | |||||||
| 5 | ZIP | ASP | ADSP | ||||
| 4th | ATP | AEP | NBP | RTMP | |||
