End-to-End Network Testing:
Three questions, one solution End-to-end (E2E) network testing is critical for service providers. Here, we look at why E2E network testing is important, as telcos look to introduce Open RAN architectures into their networks. We’ll examine what some of the common problems are and offer a solution to service providers’ testing times. E2E testing means services providers can replicate real enduser scenarios to ensure that their network is able to withstand high demand. With 5G deployment gathering momentum, they must ensure that networks can concurrently support the number and variety of use cases technology will enable. They’re not just testing to deliver superior services for subscribers – they’re bound by service level agreements and KPIs which must be met in order to realise ROI on network. What does E2E network testing involve? It requires service providers to check hardware and software components and how they work within the wider network infrastructure. It involves validating network performance as experienced by end users, across multiple cells and different radio access technologies, from RAN to core, including emerging cloudbased architectures. The diversity of E2E testing can reduce costs in finding and troubleshooting issues and helps operators deploy – and monetise – new products and services.

Testing new softwarecentric networks
Open RAN architectures including O-RAN is attracting interest from telcos as they look to introduce more software into their networks, reduce costs and diversify their supply chains. It takes time to integrate O-RAN components from different vendors and make sure Monojit Samaddar Country Director, they work properly together. E2E VIAVI Solutions, India testing also requires advanced automation that is agnostic to the vendor, facilitates software maintenance & upgrades and ensures that service level KPIs remain unchanged. The maturity of O-RAN and the speed of deployment will depend on plug-and-play capability of both hardware and software. How can service providers conduct reliable, advanced E2E network testing, meet service level agreements and deliver a superior quality of service? By picking the most robust, reliable and advanced suite of test solutions. What should they look out for? First, breadth of test features. Second, evidence that a solution works for a wide variety of
