Network functions virtualization (NFV) has introduced one of the most profound paradigm shifts for the networking industry to date. But while carriers agree on the need and vision for NFV, many are struggling to quantify the benefits, understand the practical migration steps, and measure success.
A new eBook from Ixia, “Demystifying NFV in Carrier Networks: A Definitive Guide to Successful Migrations,” aims to help companies fast-track NFV planning and deployment. The eBook provides background on NFV, highlights the potential benefits it stands to deliver, and explores obstacles to deployment and strategies for overcoming them.
With NFV, proven functions such as routing, policy, firewall, and DPI will move from running on dedicated hardware appliances to running on unproven virtualized server platforms in the hope of achieving massive efficiencies. Where the capabilities and performance of physical devices are well known and understood, virtualizing various network functions makes these aspects unknown once again. NFV effectively means having to create and manage a “carrier-grade cloud.” From beginning to end, the eBook says, carriers need targeted test strategies and methodologies to accelerate and ensure the delivery of NFV solutions.
The eBook offers specific strategies for approaching and validating decisions including:
- Evaluating new devices and architectural models
- Replicating the complexities of virtualized wireless networks
- Measuring and guaranteeing subscriber quality of experience (QoE)
- Simulating security attacks
- Monitoring live virtual networks
The Ixia eBook looks at several use cases for validating the virtualization of critical networks and functions, highlighting the need for carriers to evaluate existing network elements with an eye toward determining 1) whether the business case supports NFV migration, and 2) how performance might be affected. The biggest risks and challenges of virtualization center on guaranteeing quality and performance. Download your copy of “Demystifying NFV in Carrier Networks” to better understand when it makes sense to virtualize an aspect of the network and when it doesn’t. Executed correctly, NFV represents greater ability to roll out new, more compelling, and profitable services faster, and with guaranteed quality.
