Link Access Procedure for Frame Relay
In this article, we will delve into the topic of Link Access Procedure for Frame Relay, which has aroused great interest and debate in different areas. Link Access Procedure for Frame Relay is a topic that has become the focus of attention of experts, academics and specialists in the field, due to its relevance and impact in different sectors. Over the last decades, Link Access Procedure for Frame Relay has been acquiring greater importance and relevance, generating endless questions and concerns about its influence on today's society. In this article, we will analyze in detail and exhaustively the different facets of Link Access Procedure for Frame Relay, with the aim of providing a complete and well-founded overview of this topic.
In wide area network computing, Link Access Procedure for Frame Relay (or LAPF) is part of the network's communications protocol which ensures that frames are error free and executed in the right sequence.
LAPF is formally defined in the International Telecommunication Union standard Q.922. It was derived from IBM's Synchronous Data Link Control protocol, which is the layer 2 protocol for IBM's Systems Network Architecture developed around 1975. ITU used SDLC as a basis to develop LAPF for the Frame Relay environment, along with other equivalents: LAPB for the X.25 protocol stack, LAPM for the V.42 protocol, and LAPD for the ISDN protocol stack.
In Frame Relay Local Management Interface (LMI) messages are carried in a variant of LAPF frames.
LAPF corresponds to the OSI model Data Link layer.
