Campus Wireless Networks Validated Reference Design Version 3.3 | Design Guide Aruba’s User-Centric Network Architecture | 13
Remote AP
Using the Remote AP license, the AP can be used as a remote access device across a WAN. Plugging in
to any Internet capable Ethernet port, the AP will create a secure tunnel using IPSec (AES) to a
designated Mobility Controller. Typically this is done at corporate headquarters, or in regional data
centers around the world for global deployments. The same SSIDs, authentication, and security are
then available anywhere in the world.
This provides an on-demand corporate hotspot with the same security and access to resources that
users will find at the corporate campus without having to install additional software or be subject to a
software learning curve. Unlike a software VPN that provides only a limited set of services, using the
Aruba Remote AP license extends the entire corporate WLAN experience with the same powerful User-
Centric Security.
Mobility Management System
Wireless networking doesn’t make the IT administrator’s job easier; in fact, it can make the job
considerably harder. There are no longer any wires to trace, and IP address information only tells you
where that user started their day. The MMS consists of a new set of tools to help administrators
understand and visualize the wireless network they are administering. It is designed to provide network
administrators with the ability to effectively manage multiple Master/Local clusters in the network. The
user-centric management model allows administrators to rapidly visualize all network objects related
to the user in real-time; drastically reducing the mean-to-resolution (MTTR) while ensuring a high
quality WLAN user experience.
The Mobility Management System™ consists of a built-in location API that enables external systems to
query the location of any WLAN device. The Mobility Management System software can be deployed on
any PC platform (Linux or Windows 2003) or as an option, can be purchased as an enterprise class,
hardened appliance.
One controller in each Aruba deployment is designated as the Master Controller. The Master Controller
can also manage “Local” controller pairs, or clusters, in a high-availability configuration. However, once
