ADM AntiNAT

ADM AniNAT is a high-performance logger of network address translation machine records containing the information about each and every fact of conversion of private subscriber's address into a public one. The data is collected in real-time and is immediately available through a WEB-interface.

ADM AntiNAT
Characteristics
Data import speed up to 2 million records per second on 1 server
Data processing speed up to 300 thousand messages RADIUS, NetFlow, Syslog per second
Total cluster capacity dozens of petabytes
Hardware requirements standard COTS servers
Architecture

ADM AntiNAT is connected to the provider network via the following interfaces: Syslog or Netflow and RADIUS.

Via the RADIUS interface and RADIUS Accounting, AntiNAT retrieves information on subscriber data (MSISDN, IMSI, IMEI, etc.) and the allocation of IP addresses to the network subscribers. Besides that, Accounting-Request Stop messages notify the system of the end of a subscriber's session, i.e. of the termination of the address lease. In this diagram, the RADIUS client is a GGSN/PDN GW device and the RADIUS server is AntiNAT. On default AntiNAT works in Carbon Copy mode, i.e. it does not respond to the network on its RADIUS queries.

Information about the process of address translation for each TCP and UDP session is transferred via Syslog or Netflow interface.
