Introduction to LAN Protocols

This chapter introduces the various media-access methods, transmission methods, topologies, and

devices used in a local-area network (LAN). Topics addressed focus on the methods and devices used 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.
