4 NFV Implementation Challenges

Earlier this year, the European Telecommunications Standards Institute finalized their package of NFV Standards, which provide the context, framework, and definition of network functions virtualization (NFV). NFV is an exciting new technology that will bring unprecedented flexibility, operational efficiency, and scalability to datacenters and service provider networks.

Implementing NFV means significant changes to service delivery models, network topologies, and purchasing methodology for service providers, and with change comes challenge. In this post, I’ll examine four challenges that carriers may encounter when implementing NFV.

AT&T’s John Donovan indicated in a recent blog post that they would virtualize 5% of their network functions by the end of the year. Network Functions Virtualization (NFV) has the promise of easing operational pains and cutting costs for major service providers, and has been a large topic of discussion in many industry labs for the past 18 months. The rollout of NFV has been slightly slower than expected, as it represents a significant change to deployment models in place for several years. Most importantly, by changing the topology and deployment of devices supporting telecommunications services and applications, new service assurance challenges present themselves. In an upcoming post, I will examine several considerations for service assurance with NFV.
