Communication service providers (CSPs) worldwide continue to invest in virtualization of their network infrastructure, laying the groundwork for 5G and IoT services. Some have even taken the lead in accelerating service development on top of existing standards, thereby jumpstarting extensions to existing standards and defining new ones with their contributions. Moreover, CSPs continue pushing vendors to disaggregate specialized networking equipment in favor of open architectures.
This final installation in the NFV Report series covers the latest in network functions virtualization (NFV) virtual network functions (VNFs), the workhorse of NFV. These are the actual network functions that provide the desired network services. VNFs benefit from the underlying NFV Infrastructure (NFVI) that hosts these services and provides the appropriate virtualization capabilities as well as NFV MANO that orchestrates and manages the VNFs and the NFV Infrastructure to roll out NFV services.
CSPs and vendors have been working hard to build out new VNFs and enhancing existing ones with features and performance capabilities. They are also taking advantage of underlying capabilities in the NFVI and hardware where appropriate. However, new challenges have emerged like VNF silos, VNF onboarding, and VNF workload placement, the impact of which are being tackled by the standard bodies, CSPs and vendors alike.
