Thread and Flood Control Mechanism
SBR Carrier uses thread pools to process many concurrent authentication, accounting, and proxy requests. Under certain circumstances, a thread pool may be flooded by incoming requests caused by failovers or clients coming online. SBR Carrier uses the flood control feature to queue the packets (for example, first-in-first-out) until threads are available to process them.
The flood control feature does not guarantee that every received packet is processed. Even with the flood control feature properly configured, it is possible that RADIUS packets are still dropped.
