Network Function Virtualization Clause Samples

Network Function Virtualization. NFV logically partitions the resources from underlying physical hardware resources. NFV management and orchestration (MANO) involves the life cycle management of network service and the virtual network function (VNF) instance. A VNF is responsible for handling specific network functions part of a service that run in one or more VMs (or containers) on top of the virtualized network, compute and storage hardware infrastructure. The NFV architecture is heavily steered by the ETSI standardisation body in the ETSI NFV ISG [4]. A high-level overview of the ETSI NFV architecture is given in Figure 6.
