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.

Virtual private networks

Organizations build networks to meet their IT networking needs. Each network carries data and applications that are specific to that organization only. Hence, the networks so built are private to that extent. Building a network that is restricted to a campus is manageable from a cost perspective, as the distances are small, and fiber can be laid to connect the various buildings within a campus. The challenge is when the connectivity is required over long distances. Every organization cannot set up a private network covering such large distances, as it is very capital intensive. Thus, the organizations use the services of a service provider who provides connectivity services. The services so provided are such that the SP infrastructure is logically partitioned into small blocks that are dedicated to each organization. Such networks, though built on public...
