NFV decouples software implementations of Network Functions from the computation, storage, and networking resources they use.<\/p>\n\n\n\n

The decoupling exposes a new set of entities, the Virtualized Network Functions (VNFs), and a new set of relationships between them and the NFV Infrastructure (NFVI). VNFs can be chained with other VNFs and\/or Physical Network Functions (PNFs) to realize a Network Service (NS).<\/p>\n\n\n\n

The Network Functions Virtualization Management and Orchestration (NFV-MANO) architectural framework has the role to manage the NFVI and orchestrate the allocation of resources needed by the Network Services and VNFs.<\/p>\n\n\n\n

Benefits of NFV<\/strong><\/p>\n\n\n\n

Network Operators who prefer virtualization of their network can save money, shorten the time-to-market for new or updated products, and better scale and adjust resources available to applications and services. Other benefits include:<\/p>\n\n\n\n

Less Vendor Lock-in<\/em><\/p>\n\n\n\n

Running VNFs (Virtual Network Functions) on COTS hardware means organizations aren\u2019t locked into proprietary, fixed-function boxes that take significant time and labor to deploy and configure.<\/p>\n\n\n\n

Greater Resource Efficiency<\/em><\/p>\n\n\n\n

A virtualized data center or other infrastructure is more efficient to operate because more can be done with less. Datacenter footprint, power consumption, and cooling requirements can all be reduced or kept the same, but with increased workload capacity. This is possible because a single server can run multiple VNFs at once therefore fewer servers are needed to do the same amount of work. When a network needs to be changed, an organization can update its infrastructure through software instead of installing and provisioning the new equipment. The instances where an organization needs to physically update its network and data centers are significantly reduced.<\/p>\n\n\n\n

Flexibility<\/em><\/p>\n\n\n\n

Organizations can use the agility of NFV to quickly adapt to changing business requirements and new market opportunities. In other words, the time-to-market period is shortened because the network infrastructure can be changed to adequately support the organization\u2019s new products. A network that has gone through NFV is also able to adjust quickly and easily to changes in resource demand as traffic coming to the data center increases or decreases.<\/p>\n\n\n\n

Scaling up and down in the number of VMs and the resources provided to them can be done automatically through SDN software.<\/em><\/p>\n\n\n\n

Traditional network architectures are defined as logical systems, usually connected to specific physical hardware or facilities, used to deliver a service. With NFV, these elements become virtualized as software installations that are placed on commodity hardware. These boxes can then be used for multiple purposes instead of a single purpose.<\/p>\n\n\n\n

An NFV platform is designed to host any of the numerous VNFs being offered on the marketplace. These VNFs are so numerous because any network service or function that is not a piece of hardware can be a VNF. These include services such as load balancing, DDoS (Distributed Denial of service) protection, and Evolved Packet Core (EPC) functions.<\/p>\n\n\n\n
