Market Scenario:
Virtual Network Function (VNF) is generally known by another name in the industry as Network functions virtualization (NFV). They are often used interchangeably, as both of them concentrate primarily on enhancing network services, unlike Software-Defined Networking (SDN), which segregates the control and forwarding plane for a centralized view of the network. Virtual network function is developed to integrate and facilitate networking components, essential to give a backup for a full virtualized environment. Additionally, a VNF handles a specific network functions that are implemented on one or more virtual machines (VMs) mounted on the hardware networing components such as servers, storage, routers, switches,and others. Seperately, a single virtual network functions could be interfaced or combined collectively as building blocks to provide a large scale network communication services.

However, VNFs faciliates many advantages for the service providers in many ways. For instance, VNFs helps to optimise the network scalability and agility, also facilitates to use of network resources efficiently. VNFs also helps to reduce the power consumption and reduces the hardware spaces as the VNFs replaces hardware components which eventually lower the opertational and capital expenditure. In the light of these factors, VNFs is expected to gain the huge popularity among the telecom service providers over the forecast period.

On the flip side, lack of specification by service providers as per the regualtory policies and security standards governed by European Telecommunications Standards Institute (ETSI) is expected to be a major challenging factor for the virtual network functions over the review period.
