The component is responsible for the interaction of the platform with the AAA server of the telecom operator via the RADIUS protocol. (AAA – Authentication, Authorization, Accounting). Used when BRAS/BNG features are enabled on the DPI Platform.
The DPI and PCRF components communicate with each other using an internal communication protocol via the TCP/IP stack. PCRF can be hosted either on a separate physical or virtual server or run on the same server along with DPI.
If multiple DPIs are used, the 1xPCRF: NxDPI scheme is used.
