This book incorporates into one reference source the material you will need to understand how Ethernet networks operate, the constraints and performance issues that affect their design and implementation, and how their growth and use can be managed both locally and as part of an enterprise network. Assuming readers have varied backgrounds in communications terms and technology, the first two chapters were written to provide a common foundation of knowledge. Those chapters cover networking concepts and network standards?two topics on which material in succeeding chapters is based. Succeeding chapters examine Ethernet concepts: frame operations; network construction; the use of bridges, routers, hubs, switches, and gateways; Internet connectivity; network backbone construction; Wireless Ethernet; Security; and the management of Ethernet networks.
