Patrik Paksy finished his studies at Budapest University of Technology and Economics (BUTE) as Computer engineer in 2012. He started to work at Ericsson as a Software Developer during his master studies, and participated in several tool and prototype development project to implement new ideas to existing products and ramp-up new projects. Later he took part in a load test tool development project as a System Engineer for network robustness and failover testing. Currently, he leads a troubleshooting and monitoring tool development as a Product Owner.


About the Presentation

Accelerate end-to-end troubleshooting in mobile networks

The complexity of mobile networks is continuously increasing, meshing whole countries, including several network functions and interfaces between them. Ericsson is one of the biggest manufacturers of network functions like radio base stations, user databases and application servers. All these functions run a software logic that handles signaling protocols, maintaining user and service information and communicates with peer functions in a standardized way. Despite the well-defined functional roles and signaling protocols, testing every node and every interface between them individually does not necessarily imply that the network as a whole behaves as requested. Therefore, network level testing of signaling sequences are necessary and useful. Automation of such a testing requires big data technology, the support of multiple protocols and smart techniques to correlate signaling messages captured on different network interfaces.

Scaling up test solutions in parallel with complexity growth requires the raise of abstraction level from entity to holistic view. Apply the concept of troubleshooting in test solutions, meaning that it is no longer the aim to identify and observe faults but it is also the aim to automatically filter the relevant data to the tester. In order to provide high quality and 99.999% availability, system stability should be frequently tested with high load. Typically the 72 hours weekend test can generate more terabytes of data which cannot be analyzed manually. This requires the application of big data technology in real-time performance testing and a new approach to focus on the most important information instead of collecting all the traffic and analyze without any automation.
