<p>A network monitoring system probe is coupled to network interfaces and captures data packets. A monitoring system processor identifies messages specific to S1-MME interfaces and identifies GUMMEI parameters in the S1-MME interface messages. The monitoring system creates MME node entries in a network topology list, each of the MME nodes corresponding to a unique GUMMEI value. The monitoring system links individual S1-MME interfaces, SCTP associations, and MME IP addresses to a particular MME in the network topology list. Using authentication messages carried on the S6a and S1-MME interfaces, the monitoring system links individual S6a interfaces and S6a interface IP address to a particular MME in the network topology list and creates one or more HSS node entries in the network topology list. The monitoring system also creates eNodeB, S-GW, and PDN-GW nodes in the network topology list and links them to IP addresses and X2, S11, and S5/S8 interfaces.</p> |
