Ericsson NFV – Here & now, but how?

  1. 1. Read our guide to NFV transformation eBriefs online, and discover how we are enabling future innovation: Transforming networks with NFV What does it take to go from NFV trial to a wider commercial operation? There are multiple strategies and approaches – so the answer really depends on operators. We have gathered learnings from working with early adopters to help you define your NFV strategy and make virtualization a reality. 30 percent lower capex VNF onboarding down to one minute 02 03 Live capacity within two hours 04 05 06 07 Making fully virtualized networks real 08 Challenges Early adopters encountered much broader challenges than simply overcoming technical obstacles – and demanded new organizational strategies and technical capabilities, such as software-defining everything, optimizing VNF performance for cloud, and OSS integration. Business case The most recent market tracker predicts the global NFV market will grow to USD 16 billion by 2021. So, a solid business case is one of our first recommendations. Management MANO capabilities must be provided across network functions and services. Network and service layers will require automation and coordination to function properly. Infrastructure An open, standards-based pre-integrated NFV infrastructure can save you years of integration time, reduce complexity, lower risk, shorten time to market and increase operational efficiency, all while laying the foundation for 5G. Reliability To ensure reliability, NFV infrastructure needs telco-grade capabilities – but managing these can be very challenging. We recommend software-defining everything when it’s time for modernization. Cloud native Thinking of overhauling your code to make better use of cloud resources? You might be better off starting from scratch when writing cloud-native NFV applications for telco environments and digital services. Performance It might seem like VNF performance can't match that of physical networks – but the other benefits of telco-grade VNFs make it well worthwhile. However, there are requirements. To secure multi-vendor network functions, you must differentiate between IT and telco workloads. Creating integrated, functional service packages and employing an agile DevOps model will secure throughput capacity and latency. Migration A comprehensive, cross-functional migration plan – one that defines an overarching blueprint, identifies dependencies, aligns efforts, budgets true cost and measures KPIs – will help you make a start and avoid getting stuck in future. Good luck! 01
