Aruba is advancing its controller-less WLAN options with a new Instant Enterprise WLAN offering. The Instant portfolio delivers a virtual controller on access points and is now being expanded with new provisioning and management capabilities.
“Many customers still choose a mobility controller for different reasons, whether it’s the need for a centralized VLAN or encryption services on an appliance, but some want another option,” Ozer Dondurmacioglu, senior director of product and solutions marketing for Aruba, told EnterpriseNetworkingPlanet .
Aruba announced it first Instant technology in November of 2011. Instant delivers controller-like features inside of the wireless access point including RF management and role based access control.
The new Aruba Instant 3.1 update expands the technology with improved video and voice optimization as well Layer 3 roaming capabilities.
Dondurmacioglu explained that the way the Instant WLAN works is that it is a single VLAN subnet, so if you were to install another subnet and you plugged the instant APs in another subnet it would create a separate VLAN. That said, there is a need to maintain mobility across VLANs which is what Instant now also provides, without a performance penalty.
