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.

Understanding and Configuring WAN Technologies

"Eventually everything connects - people, ideas, objects. The quality of the connections is the key to quality per se."
- Charles Eames

Organizations have a Local Area Network (LAN) at each office. These networks need to be connected to each other to form a single network where every endpoint on the network can communicate with every other endpoint, irrespective of the physical location, within the confines of the security policy of the organization. These LANs are connected by wide area links, and are known as Wide Area Networks (WANs).

This chapter will discuss the following topics:

  • Different types of WAN technologies
  • Virtual Private Networks (VPNs)
  • The internet as the WAN
  • Design considerations for choosing a WAN technology

The chapter also introduces Wide Area Acceleration Services (WAAS), used for WAN connectivity...
