IEEE Standard 802 for Local Area NetworksRecognizing a need for standards in the LAN market, the Institute of Electrical and Electronics Engineering (IEEE) undertook Project 802. Named for the year and month ('80 Feb) of its inception, Project 802 defined a family of low-level protocol standards at physical and data link layers of the OSI model.
In IEEE 802 terms, the OSI data link layer is divided into two sublayers: logical link control (LLC) and media access control (MAC).
The data link layer functions allocated to the LLC sublayer are:
The 802 standards have been adopted by:
PROJECT 802 OVERVIEW
ANSI FDDI STANDARDClosely related to the IEEE 802 standards is a more recently developed low-level protocol standard known as fiber distributed data interface(FDDI) developed by the American National Standards Institute (ANSI) and based on the use of fiber optic cable.
FDDI differs from the IEEE 802 standards at the physical layer and MAC sublayer, but is compatible with the IEEE standards at the LLC sublayer.
