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.

Evolution of the DC

Data centers have evolved significantly in recent years, adopting technologies such as virtualization, software defined storage, and the cloud to optimize resource utilization and increase IT agility and flexibility.

A data center hosts a lot of IT equipment from servers, to storage, to network equipment. All of this equipment has undergone a lot of change with the evolution of technology. We will explore some of the evolution that has happened in recent years in the DC technologies in the following section.

Network

Traditional data centers were built using a three-tier architecture with core, aggregation, and access layers, or a two-tier collapsed core with the aggregation and core layers combined into...
