EAP-SIM/AKA and authGateway
The authGateway functionality is implemented by multiple instances of finite state machines that accept SIM requests from the SBR Carrier simauth plug-in through the GWrelay application, and formats and transmits the requests to the HLR over the SS7 network or SIGTRAN. Figure 10 shows statistics of authentication rates with different numbers of authGateway instances on M3000 2.53 GHz.
The graph is illustrative only, and the results may vary.
These numbers are only for authentication and not for authorization, against an HLR with bearer codes, service type, and so on. We recommend that you use 5 to 10 authGateway instances for better performance results.
