In computer networking, TUN and TAP are kernel virtual network devices. Being network devices supported entirely in software, they differ from ordinary network devices which are backed by physical network adapters. The Universal TUN/TAP Driver originated in 2000 as a merger of the corresponding drivers in Solaris, Linux and BSD. [1]
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).
Researchers at the Department of Mathematics and Computer Science, Xavier University, Cincinnati OH, US are also working on the project. [2] It is one of the available networking methods for the Linux Kernel-based Virtual Machine (KVM) [3] and forms part of some Linux distributions such as Ubuntu Precise (12.04 LTS) [4] and Debian [5]
Consistent Network Device Naming is a convention for naming Ethernet adapters in Linux. It was created around 2009 to replace the old ethX naming scheme that caused problems on multihomed machines because the network interface controllers (NICs) would be named based on the order in which they were found by the kernel as it booted.
Virtual devices may also operate in a non-virtualized environment. For example, a virtual network adapter is used with a virtual private network, while a virtual disk device is used with iSCSI. A good example for virtual device drivers can be Daemon Tools. There are several variants of virtual device drivers, such as VxDs, VLMs, and VDDs.
The Virtual Interface Architecture (VIA) is an abstract model of a user-level zero-copy network, and is the basis for InfiniBand, iWARP and RoCE.Created by Microsoft, Intel, and Compaq, the original VIA sought to standardize the interface for high-performance network technologies known as System Area Networks (SANs; not to be confused with Storage Area Networks).
It was jointly developed by Microsoft and 3Com Corporation and is mostly used in Microsoft Windows.However, the open-source NDISwrapper and Project Evil driver wrapper projects allow many NDIS-compliant NICs to be used with Linux, FreeBSD and NetBSD.
Though not directly accessible to the user, the virtual switch provides connectivity between all VNICs configured on the same physical interface, enabling the virtual network in a box scenario. The virtual switch forwards packets between the system's VNICs. Thus, packets from an internal VNIC source never have to pass to the external network to ...
