IEEE Project 802
The visual depicts a number of the standards that make up IEEE Project 802. Project 802 comprises a variety of LAN standards dealing primarily with Physical Layer and Data Link Layer issues. The most important LAN standards include the basic Media Access Control (MAC) standards for Ethernet and wireless LANs, the standard on Logical Link Control (LLC), and the standards related to bridging, security, VLANs, and QoS.
The other IEEE Project 802 standards are also important in certain environments. A brief description of each is provided below.
- IEEE 802: Overview and Architecture: A part of the IEEE 802.1 series, this standard describes the overall architecture of IEEE Project 802 and gives an overview of the principal components.
- IEEE 802.1: Glossary, Network Management, and Internetworking: IEEE 802.1 is a series of standards dealing primarily with bridging (802.1D), virtual LANs (802.1q), quality of service (802.1p), and network management. Other topics covered include definition of terms (i.e., glossary), project overview (i.e., IEEE 802), and inter-operation with other protocols and environments (e.g., OSI).
- IEEE 802.5: Token Ring: Although this is LAN MAC, it is one that is considered a legacy technology throughout the industry and has all but disappeared.
- IEEE 802.15: Wireless Personal Area Networking (WPAN): The initial version was adapted from Bluetooth and provides communication among portable digital devices, including access to the Internet.
- IEEE 802.16: Broadband Wireless Access: This group is specifically focused on wireless metropolitan area networks (MAN).
- IEEE 802.x: In this diagram, this is a placeholder for future and evolving MAC schemes; it does not represent a specific standard. The IEEE is very active and continually looking to respond to industry and market needs, so Project 802 is highly dynamic.
