ArubaOS and Mobility Controller

This section describes Aruba’s operating system features, optional add-on modules and the Mobility Controller that comprise Aruba’s User-Centric Network Architecture.

ArubaOS

The ArubaOS serves as the operating system and application engine for all Aruba Mobility Controllers, and is the core component that enables user-centric networks. Standard with every Aruba Mobility Controller, ArubaOS provides unprecedented control over the entire mobile environment enabling Aruba’s unique adaptive wireless LANs, identity-based security, and application continuity services.

The main features of ArubaOS include:

zSophisticated authentication and encryption

zProtection against rogue wireless APs

zSeamless mobility with fast roaming

zAdaptive RF management and analysis tools

zCentralized configuration

zLocation tracking and more

ArubaOS also offers the following optional add-on modules that provide advanced capabilities including wireless intrusion protection (WIP), identity-based security with user-centric policy enforcement, mobile Network Access Control (NAC), secure remote access, and advanced network connectivity technologies.

zWireless Intrusion Protection

zPolicy Enforcement Firewall

zVPN Server, Remote AP

zExternal Services Interface

zVoice Services Module

zWireless Mesh, and xSec Advanced L2 Encryption.

A complete description of all software modules is available in Appendix A, “Licenses” on page 67 of this document.
