As the explosion of data and proliferation of smart devices pushes traditional networks to their limits, service providers are looking towards network functions virtualization (NFV) for savings and innovation opportunities. NFV holds the potential to create ground-breaking ways to reduce costs and deliver services by consolidating different types of network equipment onto high-volume servers, switches, and storage. The hard work lies in bridging the promise of the technology with the reality of making significant changes to existing infrastructure.
To fulfill the promise of NFV, mobile network operators need to overcome a new set of challenges. A complementary eBook for SDxCentral members from Openet and Red Hat outlines the most important criteria for providers to consider when deploying virtualized server-based applications in place of dedicated hardware appliances. [sdnpdf pdf=”https://www.sdxcentral.com/wp-content/uploads/2014/10/Openet-and-RedHat-eBook-Why-Mobile-Network-Operators-are-Embracing-Virtualization.pdf” channel=”Red-Hat-Openet-Avnet-NFV-eBook-2014-10-27″ title=”“Why Mobile Network Operators Are Embracing Virtualization””] looks at how operators can use virtualization successfully to deliver network services reliably, at scale, and with a different cost structure from traditional networks.
When implemented correctly, NFV can dramatically improve network flexibility and reduce operational and capital expenses. The NFV guidebook looks at the main approaches to virtualizing the infrastructure, and it outlines the three main conditions operators must consider to ensure NFV achieves desired gains for service delivery:
- Performance: understand performance limitations of COTS hardware and ensure hypervisor, media, and signaling capabilities are optimized
- Resiliency: make sure virtualized applications are sufficiently resilient to both hardware and software failure and outages
- Orchestration: automate and monitor functions and workloads to achieve faster time to market, targeted service introductions, and elastic scaling
Complementary to SDxCentral members, the NFV guidebook presents a real-world example of a major U.S. Tier 1 operator successfully using NFV in its network. Deployed by Openet using Red Hat’s Enterprise Virtualization and KVM hypervisor technology, the virtualized policy management solution supports 100 million subscribers and is capable of handling more than one million transactions per second (TPS) in real time.
NFV is more than just virtualization of network functions. It holds the potential to change the entire telecommunications industry.
