Overview of this book

Most enterprises use Cisco networking equipment to design and implement their networks. However, some networks outperform networks in other enterprises in terms of performance and meeting new business demands, because they were designed with a visionary approach. The book starts by describing the various stages in the network lifecycle and covers the plan, build, and operate phases. It covers topics that will help network engineers capture requirements, choose the right technology, design and implement the network, and finally manage and operate the network. It divides the overall network into its constituents depending upon functionality, and describe the technologies used and the design considerations for each functional area. The areas covered include the campus wired network, wireless access network, WAN choices, datacenter technologies, and security technologies. It also discusses the need to identify business-critical applications on the network, and how to prioritize these applications by deploying QoS on the network. Each topic provides the technology choices, and the scenario, involved in choosing each technology, and provides configuration guidelines for configuring and implementing solutions in enterprise networks.

Network Building Essentials

"Alone we can do so little; together we can do so much."
- Helen Keller

Information technology (IT) has become an integral part of any modern business. This reliance on the use of technology has led to a lot of successful new businesses, and even a small delay in adopting new technology, not to mention a lack of willingness to adopt new technologies, has led to the elimination of so many businesses around the world.

Networks are the foundation for IT, as they help connect multiple elements in the technological landscape of any organization. In this chapter, we will discuss the basic concepts that the reader will find useful in their goal of learning how to build IT networks. We will cover the following topics in this chapter:

  • The need for networking and an introduction to IT networks
  • A standard reference model for a network called the Open Systems Interconnection (OSI) model
  • The TCP/IP protocol stack
  • The various stages in building a network
