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.

Designing a sample DC

We will describe a sample DC in this section to show the actual use of the technologies discussed in the preceding sections.

A data center is the most crucial part in an organization's IT network. All services in the organization's IT environment, including business critical databases and applications, are hosted within the data center. Any outage in these services or applications can lead to a loss of revenue for the organization and therefore building redundancy into the overall data center design is paramount. This redundancy has to be built to cater to all failure scenarios including network failure, firewall failure, server failure, and so on. We will discuss the various techniques and designs used to build redundancy in the DC in the sample DC configurations.

A sample DC design from a physical topology perspective is shown in the following...
