Case Study: a mobile operator accelerates LTE deployment and resolves DNS performance issues with NETSCOUT nGenius

Mobile Operator Leverages nGenius Solution to Accelerate 4G Long Term Evolution Network Deployment

A North American mobile operator with over 90 million subscribers was deploying a new LTE/EPC network. During testing, they encountered a critical and intermittent latency issue with their Domain Name System (DNS), which was causing significant delays to their deployment schedule. Their existing tools could not handle the volume of test traffic or provide an end-to-end view to troubleshoot the complex problem. The operator engaged NETSCOUT, deploying its nGenius solution with InfiniStream appliances for visibility.

The NETSCOUT nGenius solution provided comprehensive performance visibility across the entire network, allowing engineers to capture and analyze the massive data flows. They isolated the root cause to misconfigured policies on a load balancer and DNS servers. By rectifying this, they resolved the performance problem. According to the customer, NETSCOUT's solution reduced the troubleshooting effort by at least two weeks, preventing major delays and keeping the critical LTE network deployment on schedule.
