While the promises of software-defined networking (SDN) and network functions virtualization (NFV) are becoming more widely known, capitalizing on the technology's opportunities requires service providers to take a practical, planned approach. Failing to strategically organize these transformations may mean not experiencing the revenue and operational benefits of virtualization until further down the road.
Partnering with European Communications on a survey of more than 60 service providers, Netcracker identified their virtualization programs' goals, potential obstacles and anticipated timeframes.
The study found that despite properly aligned priorities and goals, service providers often face many practical and technological barriers that impede progress. However, by observing faster-than-average transformations, the report surmised eight best practices.
Adopting SDN/NFV will inevitably bring about technological and organizational shifts which require alignment between IT and business priorities. It’s essential that the shift be examined and approached in a practical manner to avoid putting revenue streams at risk.
The study found that missing a strong business case was among the top challenges when implementing SDN/NFV. Service providers must ensure that business case objectives are clear, pragmatic and compelling.
Service providers must review their systems, processes and internal resource requirements, paying extra attention to problematic areas. One of the best ways to ensure a comprehensive review is to work closely with a trusted partner that has the expertise to overcome technology challenges.
Taking the time to establish planned checkpoints and perform “health checks” along the way with a trusted partner is important. This will help to determine and evaluate the progress of the transformation.
