Chapter 12. Network design for the enterprise > Enterprise network - Pg. 266

12.1 Enterprise network The enterprise is a growing and ever changing environment. Between large campuses with multiple buildings, to regional offices as well as small sites. The basic requirement is always to connect end devices such as user workstations, wireless access points, printers, and Voice over IP phones to a network in order to provide access to the services within the data center. As previously mentioned in this book, we will treat the data center as the main hardened facility housing the systems and services that require high availability and performance characteristics. The enterprise accesses the applications housed in the data center through the links such as the WAN and LAN as shown in Figure 12-1.
