Optional Session State Register (High Availability) Module
The Steel-Belted Radius Carrier Session State Register (SSR) module implements a stateless high-availability AAA platform. Multiple servers of different types (data, management, and SBR Carrier) perform certain aspects of SBR Carrier operation. The servers collaborate to share a common session database and a common IP address pool, and to provide a high level of redundancy. The common shared resources can be accessed simultaneously by up to 20 SBR Carrier servers.
