Dubbed Aruba HybridControl, the new code gives Aruba's 7200 Mobility Controller massive scalability. Aruba says the software update will let the 7200 manage over 32,000 hotspots. That translates into over 100,000 individual access points, because each hotspot can have several of the vendor's Aruba Instant access points. The scaling lowers carriers' backend capital costs, cuts data center power demand, and needs less rack space, according to Aruba. The Aruba Instant model offloads cellular traffic locally to the Internet, while centralizes selected traffic such as billing and legal intercept via an IPSec connection to the 7200 controllers at the core.
HybridControl offers "zero-touch activation" for factory-default access points, with no need for any manual pre-provisioning. Switched on, these access points interface with the Aruba Activate cloud service to discover the carrier's configuration management system and download it. Then, the access points use an assigned X.509 certificate to authenticate with an Aruba controller and set up an IPSec tunnel.
The HybridControl architecture leverages existing Aruba features such as:
- AppRF, to identify and prioritize real-time applications, such as Microsoft Lync, to create different classes of service;
- ClearPass Policy Management, a server application to authenticate new access points joining the mobile core network.
The carrier-focused HybridControl offering includes several products: the Aruba 7200 Mobility Controller, available now with prices starting at $38,000; Aruba Instant access points, available now with prices starting at about $400; Aruba Activate, available now and free of charge for Aruba customers. The software update for the 7200 will be available as a free Aruba OS upgrade in the second quarter.
