Chapter 12. NETWORK DESIGN

NETWORK MANAGERS perform two key tasks: (1) designing new networks and network upgrades and (2) managing the day-to-day operation of existing networks. This chapter examines network design. Network design is an interative process in which the designer examines users' needs, develops an initial set of technology designs, assesses their cost, and then revisits the needs analysis until the final network design emerges.
