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 network server.
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
It is common for the operating system kernel to maintain a table of virtual network interfaces in memory. This may allow the system to store and operate on such information independently of the physical interface involved (or even whether it is a direct physical interface or for instance a tunnel or a bridged interface).
A virtual local area network (VLAN) is any broadcast domain that is partitioned and isolated in a computer network at the data link layer (OSI layer 2). [ 2 ] [ 3 ] In this context, virtual refers to a physical object recreated and altered by additional logic, within the local area network .
6WIND Virtual Accelerator – Provides high performance virtual networks from the underlying hardware acceleration and was pioneered on using fast path software and DPDK technologies VMware / Nicira NVP – Separates virtual networks from the underlying hardware and was pioneered by Nick McKeown , Scott Shenker , and Martin Casado in 2007.
Network functions virtualization (NFV) [1] is a network architecture concept that leverages IT virtualization technologies to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create and deliver communication services.
Virtual Distributed Ethernet (VDE) is a set of programs to provide virtual software-defined Ethernet network interface controllers (NICs) across multiple devices, typically computers, which are either virtual or physical.
A virtual private network (VPN) is an overlay network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires. The data link layer protocols of the virtual network are said to be tunneled through the larger network.
