PART THREE NETWORK TECHNOLOGIES

CHAPTER 6NETWORK DESIGN

The chapters in the first section of the book provided a fundamental understanding of how networks work using the five-layer model. This chapter starts the next section of the book, which focuses on how we design networks. We usually design networks in seven network architecture components: local area networks (LANs), building backbone networks, campus backbones that connect buildings, wide area networks (WANs) that connect campuses, Internet access, e-commerce edge, and data centers. 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.

OBJECTIVES

• Understand the seven network architecture components
• Describe the overall process of designing and implementing a network
