For example, a multicast router may operate differently on interfaces that represent tunnels than on physical interfaces (e.g. it may only need to collect membership information for physical interfaces). Thus the virtual interface may need to divulge some specifics to the user, such as whether or not it represents a physical interface directly. [1]
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]
A network interface controller (NIC, also known as a network interface card, [3] network adapter, LAN adapter and physical network interface [4]) is a computer hardware component that connects a computer to a computer network. [5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.
Networking hardware typically refers to equipment facilitating the use of a computer network. Typically, this includes routers, switches, access points, network interface cards and other related hardware. This is a list of notable vendors who produce network hardware.
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 forms part of the Virtual Square [1] project from the Italian Bologna University whose code is available on public servers using free software licenses, mostly GPLv2. Researchers at the Department of Mathematics and Computer Science, Xavier University , Cincinnati OH, US are also working on the project.
The technology enables one physical adapter card to appear as multiple virtual network interface cards (vNICs) and virtual host bus adapters (vHBAs). [2] Virtual NICs and HBAs function as conventional NICs and HBAs , and are designed to be compatible with existing operating systems , hypervisors , and applications.
Internal network virtualization configures a single system with software containers, such as Xen hypervisor control programs, or pseudo-interfaces, such as a VNIC, to emulate a physical network with software. This can improve a single system's efficiency by isolating applications to separate containers or pseudo-interfaces.
