Link Access Procedure Balanced

from Wikipedia, the free encyclopedia

Link Access Procedure Balanced ( LAPB ) is a Layer 2 protocol ( Link Access Protocol ) in the sense of the OSI layer model and is used to secure data transmission within Layer 2 in X.25 networks. It is a variant of High-Level Data Link Control (HDLC).

A distinction is made between the Asynchronous Balanced Mode (ABM) and ADM modes ; The combination of ABM and ADM is referred to in ISO 7809 as the Balanced Asynchronous Class (BAC), which in turn must be distinguished from the Universal Access Control (UAC) and UNC classes .

LAPB is defined in ISO 7776.
