2.5 Message Conversion

RCL receives RADIUS messages from peers (over server connections) and converts them to Diameter to allow them to be routed by DRL. The routable Diameter message is populated with relevant Diameter AVPs using configuration information and information from the RADIUS message. The received RADIUS message is then embedded into the converted Diameter message, providing access to the receiving RADIUS message contents for forwarding.

DRL routes the Diameter message, which eventually ends up in RCL. RCL extracts the embedded RADIUS message from the Diameter message, updates the message, and forwards it to the peer.
