Network function virtualization (NFV) is the combination of software and hardware network featured in a virtual network. The service was initiated by service operators in order to increase the deployment of new operations, maintenance and service of networks. Network function virtualization catalyzes the major changes in implementation of network and their operations. The solution offered by network function virtualization projects a prominent future by optimizing the network operations and benefitting the service providers across the globe. Network function virtualization involves implementation of network functions in software suitable for different hardware and that can be moved to various locations without any need of installation of new equipments.
The primary goals of network function virtualization are to reduce power consumption and reduce equipment cost, facilitate the accessibility of several applications on one single network appliances with multi tenancy and multi version capabilities. Network function virtualization reduces capital expenditure (CAPEX) and operational expenditure (OPEX). These networks support a dynamic ecosystem through the development and utilization of software solutions. All the benefits of FV are derived from use commercial off the shelf (COTS) hardware that can be purposed and repurposed for multiple telecom related services that currently use proprietary hardware. Network function virtualization adopts the concept of virtualization and providing the benefit to telecommunication application infrastructure. Network function visualization supports software defining network (SDN) by providing the infrastructure upon which SDN software can be run.
The market for network function virtualization is driven by several factors including increase in demand for data intensive applications and need of cloud based services. Over the past few...
