RADIUS Client – POD Replica Support

Multiple RADIUS PODs can be spawned based on the requirements. The pod replicas work as follows:

  • SMF Service requests are sent to any of the RADIUS POD using the cluster's load-balancing method. On receiving the request, the RADIUS POD initiates the access-request packet and uniquely reserves a UDP source port using the "instance-id" logic.

  • When the UDP-Proxy receives the response, it searches the actual instance of the RADIUS POD by decoding the UDP destination port value, and unicasts the packet to the respective RADIUS POD.

The following figure illustrates the working of the POD replica.
