Virtual Distributed Ethernet
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. It forms part of the Virtual Square 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. It is one of the available networking methods for the Linux Kernel-based Virtual Machine (KVM) and forms part of some Linux distributions such as Ubuntu Precise (12.04 LTS) and Debian Overview Software-defined networking is the dynamic creation of virtual network infrastructure that is completely decoupled and independent of any physical network hardware. Structure VDE (Virtual Distributed Ethernet) comprises 5 main components: VDE switch A virtual Ethernet s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ethernet
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses a thick coaxial cable as a shared medium. This was largely superseded by 10BASE2, which used a thinner and more flexible cable that was both less expensive and easier to use. More modern Ethernet variants use Ethernet over twisted pair, twisted pair and fiber optic links in conjunction with Network switch, switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the lates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Network Interface Controller
A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter and physical network interface) is a computer hardware component that connects a computer to a computer network. Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus. The low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard, or is contained into a USB-connected dongle, although network cards remain available. Modern network interface controllers offer advanced features such as interrupt and Direct memory access, DMA interfaces to the host processors, support for multiple receive and transmit queues, partitioning into multiple logical interfaces, and on-controller network traffic processing such as the TCP offload engine. Purpose The network controller implements the electronic circuitry required to communicate using a specific physica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

GPLv2
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or copyleft, ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the Lesser General Public License, GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD licenses, BSD, MIT License, MIT, and Apache License, Apache. Historically, the GPL license family has been one of the most pop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kernel-based Virtual Machine
Kernel-based Virtual Machine (KVM) is a free and open-source virtualization module in the Linux kernel that allows the Kernel (operating system), kernel to function as a hypervisor. It was merged into the Mainline Linux, mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules. KVM was originally designed for x86 processors but has since been porting, ported to IBM ESA/390, ESA/390, PowerPC, IA-64, and ARM architecture, ARM. The IA-64 port was removed in 2014. KVM supports hardware-assisted virtualization for a wide variety of guest operating systems including BSD, Solaris (operating system), Solaris, Microsoft Windows, Windows, Haiku (operating system), Haiku, ReactOS, Plan 9 from Bell Labs, Plan 9, AROS Research Operating System, AROS, macOS, ...

Linux Distributions
A Linux distribution, often abbreviated as distro, is an operating system that includes the Linux kernel for its kernel (operating system), kernel functionality. Although the name does not imply distribution (marketing), product distribution per se, a distro—if distributed on its own—is often obtained via a website intended specifically for the purpose. Distros have been designed for a wide variety of systems ranging from personal computers (for example, Linux Mint) to Server (computing), servers (for example, Red Hat Enterprise Linux) and from embedded devices (for example, OpenWrt) to supercomputers (for example, Rocks Cluster Distribution). A distro typically includes many components in addition to the Linux kernel. Commonly, it includes a package manager, an Init, init system (such as systemd, OpenRC, or runit), GNU tools and Library (computing), libraries, documentation, Internet Protocol, IP network configuration utilities, the Getty (Unix), getty TTY setup program, an ...

Ubuntu Version History
Ubuntu releases are made semiannually by Canonical (company), Canonical Ltd using the year and month of the release as a Software versioning, version number. The first Ubuntu release, for example, was #0410, Ubuntu 4.10 and was released on 20 October 2004. Consequently, version numbers for future versions are provisional; if the release is delayed until a different month (or even year) than planned, the version number will change accordingly. Canonical schedules Ubuntu releases to occur approximately one month after GNOME releases, resulting in each Ubuntu release including a newer version of GNOME. Every fourth release, occurring in the second quarter of even-numbered years, has been designated as a long-term support (LTS) release. The desktop version of LTS releases for #1004, 10.04 and earlier were supported for three years, with server version support for five years. LTS releases #1204, 12.04 and newer are freely supported for five years. Through the Expanded Security Mainte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Software-defined Networking
Software-defined networking (SDN) is an approach to network management that uses abstraction to enable dynamic and programmatically efficient network configuration to create grouping and segmentation while improving network performance and monitoring in a manner more akin to cloud computing than to traditional network management. SDN is meant to improve the static architecture of traditional networks and may be employed to centralize network intelligence in one network component by disassociating the forwarding process of network packets ( data plane) from the routing process ( control plane). The control plane consists of one or more controllers, which are considered the brains of the SDN network, where the whole intelligence is incorporated. However, centralization has certain drawbacks related to security, scalability and elasticity. SDN was commonly associated with the OpenFlow protocol for remote communication with network plane elements to determine the path of network pac ...

8P8C
A modular connector is a type of electrical connector for cords and cables of electronic devices and appliances, such as in computer networking, telecommunication equipment, and audio headsets. Modular connectors were originally developed for use on specific Bell System telephone sets in the 1960s, and similar types found use for simple interconnection of customer-provided telephone subscriber premises equipment to the telephone network. The Federal Communications Commission (FCC) mandated in 1976 an interface registration system, in which they became known as registered jacks. The convenience of prior existence for designers and ease of use led to a proliferation of modular connectors for many other applications. Many applications that originally used bulkier, more expensive connectors have converted to modular connectors. Probably the best-known applications of modular connectors are for Telephone line, telephone and Ethernet. Accordingly, various electronic interface specif ...
