How We Deployed Our Own Mobile Operator Test Lab for Core Network Testing

That is why many scenarios in mobile solution development cannot be fully tested in isolation.

Functional testing of Stingray BNG using an Ixia traffic generator

In BNG-related projects, not only performance but also predictable system behavior under different conditions is critical. Before moving on to load testing, it is important to verify that the device correctly implements both basic and advanced functions in accordance with RFC requirements. This article explains how functional testing of a BNG was organized using a test environment built according to the requirements of a nationwide telecom operator.
