Wireless Virtual Networking

- Virtual Networking Architecture

5G network slicing will allow telecommunication operators to split a single physical network into multiple virtual networks. With network slicing technology, a single physical network can be partitioned into multiple virtual networks allowing the operator to offer optimal support for different types of services for different types of customer segments. 

Network slicing can support customized connectivity designed to benefit many industries by offering a smarter way to segment the network to support particular services or business segments. With this technology, slices can be optimized by myriad characteristics including latency or bandwidth requirements. 

- Software-Defined Networking (SDN)

[Ciena]: "Software-Defined Networking (SDN) is a network architecture approach that enables the network to be intelligently and centrally controlled, or ‘programmed,’ using software applications. This helps operators manage the entire network consistently and holistically, regardless of the underlying network technology." 
SDN technology is an approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance and monitoring making it more like cloud computing than traditional network management.

- Network Functions Virtualization (NFV)

[Juniper Networks]: "Network Functions Virtualization (NFV) abstracts network functions, allowing them to be installed, controlled, and manipulated by software running on standardized compute nodes. NFV incorporates cloud and virtualization technologies to drive rapid development of new network services with elastic scale and automation. These technologies are often grouped as NFV and software-defined networking (SDN)."  

NFV is a network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services. NFV relies upon, but differs from, traditional server-virtualization techniques, such as those used in enterprise IT. A virtualized network function, or VNF, may consist of one or more virtual machines running different software and processes, on top of standard high-volume servers, switches and storage devices, or even cloud computing infrastructure, instead of having custom hardware appliances for each network function.
