The potential benefits of NFV is anticipated to be significant. Virtualization of network functions deployed on general purpose standardized hardware is expected to reduce capital and operational expenditures, and service and product introduction times. [22] [23] Many major network equipment vendors have announced support for NFV. [24]
Network virtualization involves platform virtualization, often combined with resource virtualization. Network virtualization is categorized as either external virtualization, combining many networks or parts of networks into a virtual unit, or internal virtualization, providing network-like functionality to software containers on a single ...
In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.

The Crossbow project software, combined with next generation network interfaces like xge and bge, enable network virtualization and resource control for a single system. By combining VNICs with features such as exclusive IP zones or the Sun xVM hypervisor, system administrators can run applications on separate virtual machines to improve performance and provide security.
Dataflow for communication payload leveraging network protocol virtualization software. Network Protocol Virtualization (NPV) was firstly proposed by Heuschkel et al. in 2015 as a rough sketch as part of a transition concept for network protocol stacks. [1] The concept evolved and was published in a deployable state in 2018. [2]
The virtual access layer (VAL) refers to the virtualization of the access layer that connects servers to the network in the data center. Server virtualization is now aggressively deployed in data centers for the consolidation of applications hosted on x86 servers. However, the underlying limitations in current networks prevent organizations ...
The VF can be realized as a traditional software firewall on a guest virtual machine already running, a purpose-built virtual security appliance designed with virtual network security in mind, a virtual switch with additional security capabilities, or a managed kernel process running within the host hypervisor.
Singularity is a free and open-source computer program that performs operating-system-level virtualization also known as containerization. [4]One of the main uses of Singularity is to bring containers and reproducibility to scientific computing and the high-performance computing (HPC) world.
