With the shortage of IP V4 addresses, operators are moving towards NAT or the use of IPV6 and in both cases a system of traceability of IP sessions is essential. PYXIS CGNAT Log Management System satisfies this need for traceability and data retention by offering the complete history of subscriber navigation, location-based information, NAT information, APN for a given period of time that is stored and analyzed correctly with the BIG DATA architecture.

Security challenge and requirements

In order to comply with the regulator requirements, the telecom operators need to establish an IP Log Management System that allows querying in real time about active and historical sessions from a web interface.

The proposed solution should be:

• Multi-vendor solution for processing and storing NAT logs.
• Supports multiple suppliers’ hardware both for Dynamic Allocation and for PBA.
• High number of log packet capturing and correlation capacity.
• Supports Syslog / Netflow and any open logging protocol.
• Integrated with AAA, external DB for queries about subscriber ID.
• Scalable according to the demand and the needs of each NAT implementation.
• Able to store both NAT Logs for a defined duration.
• Support IPv4, IPv6 and Dual IP support.
• Adaptor based module support for different and new type of log streams.
• Distributed architecture with collector and cabinet units.
• Store and forward network level caching.
• Sophisticated user credential management.
• Enhanced RADIUS/DHCP logging correlation of user data with traffic logs.
• Operating as an On Demand Query solution where all logs would be stored in a proper unified format as per the supplier’s software build and at the time of query the solution will fetch records and produce the results to show on the GUI.
