Aruba mobility controllers are high-performance networking platforms built specifically to run centralised ArubaOS functions such as controlled access point management, 802.11x authentication and encryption, site-to-site and client VPNs using IPSec/3DES encryption, stateful policy enforcement firewalls, endpoint integrity checking, and seamless user roaming between access point and across mobility controllers.
All Aruba mobility controllers share a common hardware architecture which includes a dedicated control plane CPU, a high-performance data plane network processor unit, and a unique programmable encryption engine for centralised L2 and L3 encryption. They aggregate traffic from the mobile edge, inspect and police it and deliver it to the core enterprise network. Mobility controllers are typically positioned in data centers, for a controlled environment and access to the high-speed core network, since they handle traffic from hundreds of APs and thousands of users.
