AS 4802.2-1991

Describes the functions, features, protocol, and services of the Logical Link Control (LLC) sublayer in the ISO 8802 Local Area Network Protocol. The LLC sublayer constitutes the top sublayer in the data link layer and is common to the various medium access methods that are defined and supported by the ISO 8802 activity. This Standard provides a description of the peer-to-peer protocol procedures that are defined for the transfer of information and control between any pair of data link layer service access points on a local area network. The LLC procedures are independent of the type of medium access method used in the particular local area network. This Standard is technically identical with and has been reproduced from ISO 8802-2:1989.
