The Institute of Electrical and Electronic Engineers (IEEE) created the 802 committee in 1980. The committee drafts standards for LAN. The subcommittees of802 addresses a specific LAN architectures. They are referred as LAN types or subgrouping. These groups and their responsibilities are listed below.
802.1 : The high level interface standard addresses matters related to network architecture, management and interconnection.
802.1a : Network Management Architecture
802. 1b : Network management protocols
802.1D : Bridging standard
802.1d : Source routing standard
802.1g : Remote bridge standard for WANs
802.1P : Prioritization of MAC layer bridges
802.1Q : Virtual LANs (VLAN)
802.2 : Logical link control (LLC) and media access control (MAC) are two sublayers that are equivalent to OSI data link layer
802.2Í and j : Acknowledged connectionless LLC service
802.3 : Carrier sense multiple access with collision detection (CSMA/CD)
standards cover a variety of architectures that are generally based on Ethernet.
802.3Í : CSMA/CD over twisted pair and fiber obtics
802.3m : Fast Ethernet
802.3x : Gigabit Ethernet flow control
802.3z : Gigabit Ethernet
802.3ab : Gigabit on category 5 UTP cabling
802.4 : The token bus network standard describes how the token bus network operates.
802.5 : Token ring network. 802.5j : Fiber optic token ring
802.6 : The MAN standard describes the operations of networks covering large distances.
802.7 : The broadband Technical Advisory Group provides guidelines to other groups that are involved in establishing broadband LAN standards.
802.8 : The Fiber optic Technical Advisory group provides guidance to other groups that are involved in establishing LAN standards using fiber optic cable.
802.9 : Integrated data and voice networks
: Isochrononous Ethernet (ISONET)
