Background

The term Ethernet refers to the family of local-area network (LAN) products covered by the IEEE 802.3 standard that defines what is commonly known as the CSMA/CD protocol. Three data rates are currently defined for operation over optical fiber and twisted-pair cables:

10 Mbps— 10Base-T Ethernet 100 Mbps— Fast Ethernet 1000 Mbps— Gigabit Ethernet

10-Gigabit Ethernet is under development and will likely be published as the IEEE 802.3ae supplement to the IEEE 802.3 base standard in late 2001 or early 2002.

Other technologies and protocols have been touted as likely replacements, but the market has spoken. Ethernet has survived as the major LAN technology (it is currently used for

approximately 85 percent of the world's LAN-connected PCs and workstations) because its protocol has the following characteristics:

Is easy to understand, implement, manage, and maintain Allows low-cost network implementations

Provides extensive topological flexibility for network installation

Guarantees successful interconnection and operation of standards-compliant products, regardless of manufacturer
