Introduction

This design guide is one of a series of books that describes Aruba’s User-Centric Network Architecture and provides network administrators with guidelines to design and deploy a centralized enterprise-wide wireless LAN (WLAN) network for the most common customer scenarios.

This guide complements the technical documentation you received with software and hardware releases for Aruba components.

Aruba Reference Architectures

An Aruba Validated Reference Design (VRD) is a package of network decisions, deployment best practices, and detailed descriptions of product functionality that comprise a reference model for common customer deployment scenarios. The VRD presented in this guide is representative of a best practice architecture for a large Campus WLAN serving thousands of users spread across many different buildings joined by SONET, MPLS, or other high-speed, high-availability network backbone.

The Campus Wireless Network is one of five reference architectures commonly deployed by our customers. For a brief description of the other deployment models refer to Appendix C, “Alternative Deployment Architectures” on page 71.
