Viavi Solutions has revealed that virtualisation (78 per cent), automation (70 per cent) and network slicing (70 per cent) are the top technology trends increasing the need for test, monitoring and assurance, according to communications service providers (CSPs).
These findings are explained in The 2021 Network Test Survey, an industry report commissioned by VIAVI that explores insights into how the pandemic and other trends are shaping test and assurance priorities in 2021 and beyond.
The past year has been a proving ground for both wired and wireless networks worldwide, with hundreds of millions of people working remotely and educating their children from home. Despite substantial increases in network traffic, today’s networks in large part met the global challenges created by the pandemic.
In the survey, 85 per cent of respondents stated that in-person network technician visits had been reduced or eliminated as a result of the pandemic, although 78 per cent said that the change was temporary. More than 55 per cent of service providers report a transition from instrument-based testing to remote, virtualised testing, with 7 per cent saying the change is permanent. In order to maintain quality of experience during the pandemic, at least 30 per cent of service providers increased reliance on contractors for network quality assurance.
More than two-thirds (70 per cent) of CSPs identify access network performance as the primary factor that most impacts subscriber experience, with transport network performance (41 per cent) and core network performance (37 per cent) also of concern. An overwhelming majority (93 per cent) believe that testing improves customer satisfaction and reduces churn.
“Prior to the pandemic, service providers had begun turning to technologies like automation, AI and virtualisation to control costs while improving the customer experience. The current situation has only accelerated the adoption of these advanced technologies,” said Kevin Oliver, Vice President and General Manager, Converged Instruments and Virtual Test, Viavi. “To ensure performance of more complex, next-generation networks, service providers need advanced test and assurance solutions and automated workflows, particularly when they are increasingly relying on contractors for crucial field testing.”
