Architecture and Deployment Flexibility

Existing architectures for supporting tunneled WLANs involve tunneling data back into controllers. This results in architectures where a complete controller needs to be deployed on each site or all the tunneled WLAN traffic being backhauled into a centralized data center. This also results in dependencies on choices for controller platforms with different capacity profiles, which increase the capital and operating expenses of the entire solution without actually solving the real problem.

With the vSZ-D/SZ100-D , it is now possible to deploy the same software either on-premise (on cheaper COTS hardware) when needed, as well as deploy it at the data center (on higher end COTS hardware) and the entire Wi-Fi management controller by the vSZ controller.
