The Challenge

A leading telecom operator faced recurring complaints about slow network performance, especially during peak business hours. The issue was often caused by network congestion, but identifying the exact location took a lengthy manual process.

Network operators had to inspect hundreds of routers individually to locate the congested link, analyse traffic patterns, and determine whether an alternative route was available. This process typically took 1–2 hours, increasing response times, affecting service quality, and impacting the overall customer experience.

The Solution

To simplify operations and accelerate issue resolution, the operator deployed iProvision to automate congestion detection and traffic optimisation.

The process began with Telemetry, which continuously collected interface utilisation data from across the network, providing a real-time view of network health. Traffic Analytics then monitored this data and automatically detected links that crossed the predefined utilisation threshold, allowing potential congestion to be identified instantly and reducing the need for manual checks.

To make troubleshooting even easier, the Live Topology module visually highlighted the affected links, enabling operators to quickly pinpoint the exact location of the issue without manually reviewing multiple devices and speeding up resolution.

Once congestion was identified, Traffic Engineering analysed the available network paths to determine the best alternative route for traffic. Dynamic CSPF calculated the most efficient path based on current network conditions, ensuring traffic could be redirected without creating new bottlenecks and improving traffic flow.

The recommended path was then reviewed by the operator and seamlessly deployed through the PCEP Controller, allowing traffic to be rerouted with minimal operational effort and service disruption, helping restore performance quickly.

Business Benefits

By automating congestion detection and traffic optimisation, the telecom operator significantly improved network operations and customer experience by reducing manual effort and speeding up issue resolution.

• Detected network congestion in real time instead of relying on customer complaints, helping operators respond sooner.
• Reduced troubleshooting time from 1–2 hours to just a few minutes, improving response speed.
• Improved application and network performance during peak traffic periods by resolving congestion faster.
• Minimised customer complaints through faster issue identification and resolution, improving the customer experience.
• Maximised the utilisation of existing network capacity without additional infrastructure investments by rerouting traffic more efficiently.
• Enabled network teams to focus on proactive optimisation instead of manual troubleshooting, improving operational efficiency.

Outcome

With iProvision, the operator transformed a reactive, time-intensive troubleshooting process into an intelligent, automated workflow, enabling faster decisions, optimised traffic routing, and a more reliable network experience for customers.
