Quebec City firm launches intelligent network automation platform

EXFO Inc., Quebec City-based test, monitoring and analytics experts for the communications industry, has launched Nova Adaptive Service Assurance (Nova A|SA), the first intelligent automation platform enabling mobile network operators to deliver ultra-reliable, high-quality service experience in a 5G world. 

To meet the needs of an industry in which operators have less than 2% visibility into customer experience, Nova A|SA automatically provides the right data at the right time to make sense of big data swamps and reveal previously invisible ‘little data’ on individual user experience. Unique in the industry, the platform integrates the relevant layers, domains and data sources, including from third parties and EXFO’s own portfolio of service assurance solutions.

At the heart of Nova A|SA is Nova SensAI: a real-time automated assurance solution that acts as the central nervous system for the platform. The first of its kind to do so, Nova SensAI uses machine learning to analyze the relevant network layers, and provide operators with a comprehensive view of service performance. The solution reveals—and even predicts—previously ‘invisible’ user-impacting events. Its capabilities also include pinpointing who was impacted, where and for how long as well as diagnosing the root cause of issues for rapid resolution.

Delivering only the right data at the right time

“The combination of more users, more connections, more apps and more convoluted networks has created a perfect storm of complexity for operators,” says EXFO CEO Philippe Morin. “By delivering only the right data at the right time, Nova A|SA is a unique intelligent automation platform to provide operators with 100% visibility into user experience and network performance. We’re talking about operations teams being able to resolve issues in minutes rather than days—or preventing them entirely.”


These solutions were developed by EXFO in partnership with its customers to prepare for a 5G world in which connected devices, rather than cellphone subscriptions, are expected to drive 95% of new revenues for operators. According to the GSMA, an organization representing the interests of mobile operators worldwide, there will be five times more connected devices than humans by 2025. These new 5G machines will fuel Industry 4.0 and fulfill mission-critical applications as diverse as holographic augmented reality communications, real-time remote patient monitoring and synchronized production line robots.

In addition, most customers score their brand experience on network performance, and there is enormous commercial opportunity for operators who successfully deliver on the promise of 5G and win customer loyalty. However, they are facing unprecedented challenges:

  • Operators are currently 98.7% blindto subscriber-impacting events, despite their best efforts. They are provided only with performance averages and aggregates, rather than per-subscriber problems with unique service experiences. It is only an approximate view of the health of their networks and how well they are performing.
  • 91% of operators say they need service assurance automation to maintain control.As networks continue to virtualize, outages have escalated by 46% in the last three years alone, 65% of which originate in virtualized domains.
  • Operations teams are stretched to the limit: On average, operator teams spend 67% of their time fixing network and service issues. Resolution effort and complexity of outages are increasing: it typically takes 12 people from three different teams over three hours to identify the root cause of each outage.
