The growing need for operators to increase service agility, while reducing the cost of service, is causing them to step up the pace of NFV adoption. Tier 1 operators in particular are converting early proof-of-concept (PoC) use cases such as vEPC, vIMS and vCPE to commercial pre-deployments, or full deployments. This is leading NFV advocates to strengthen broader deployment plans by turning to advanced partnerships with suppliers.
About one-fifth of operators studied view capacity upgrades as a top trigger for NFV adoption. Operators see NFV as a way to relieve legacy networks’ struggles to accommodate bandwidth demands, due to higher rates of data and video traffic, and decrease proprietary hardware required for network services
