Introduction to LAN Protocols

Objectives

• Learn about di fferent LAN protocols.

• Understand the different methods usee! to deal with media contention.

• Learn about different LAN topologies.

This; chaptef int roduces the various media-access methods, transmission methods, topologies, and devices used in a l ocal-area network (LAN). Topics addressed focus on the methods and devices uNed in Ethernet/IEEE 802.3, Token Ring/IEEE 802.5, and Fiber Distributed Data Interface (FDDI). Subsequent chapters in Part II, "LAN Protocols," address specific protocols in more detail. Figure 2-1 illustrates the basic layout of these three implementations.
