A local area network (LAN) is a computer network that interconnects computers within a single physical location. It is the most common type of computer network, used in homes and buildings including offices or schools, for sharing data and devices between each other, including Internet access. Ethernet and Wi-Fi are the two most common technologies used for local area networks; historical network technologies include ARCNET, Token Ring and LocalTalk.
The London Internet Exchange (LINX) is a mutually governed Internet exchange point (IXP) providing peering services and public policy representation to network operators, encompassing over 950 different autonomous systems (ASNs). Established in 1994 in London, LINX operates IXPs in London, Manchester, Scotland, and Wales in the United Kingdom, as well as in Northern Virginia, United States.
Bell Internet, originally called Sympatico, is the residential Internet service provider (ISP) division of BCE Inc. As of May 3, 2012, Bell Internet had over 3 million subscribers in Ontario and Quebec, making it the largest ISP in Canada.
Small Form-factor Pluggable (SFP) is a compact, hot-pluggable network interface module format used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver, such as for a fiber-optic cable or a copper cable. The advantage of using SFPs compared to fixed interfaces is that individual ports can be equipped with different types of transceivers as required, with the majority including optical line terminals, network cards, switches and routers.
Optical Carrier transmission rates are a standardized set of specifications of transmission bandwidth for digital signals that can be carried on Synchronous Optical Networking (SONET) fiber optic networks. Transmission rates are defined by rate of the bitstream of the digital signal and are designated by hyphenation of the acronym OC and an integer value of the multiple of the basic unit of rate, e.g., OC-48. The base unit is 51.84 Mbit/s. Thus, the speed of optical-carrier-classified lines labeled as OC-n is n × 51.84 Mbit/s.
Optical networking is a means of communication that uses signals encoded in light to transmit information in various types of telecommunications networks. These include limited range local-area networks (LAN) or wide area networks (WANs), which cross metropolitan and regional areas as well as long-distance national, international and transoceanic networks. It is a form of optical communication that relies on optical amplifiers, lasers or LEDs and wavelength-division multiplexing (WDM) to transmit large quantities of data, generally across fiber-optic cables. Because it is capable of achieving extremely high bandwidth, it is an enabling technology for the Internet and telecommunication networks that transmit the vast majority of all human and machine-to-machine information.
The IBM BladeCenter was IBM's blade server architecture, until it was replaced by Flex System in 2012. The x86 division was later sold to Lenovo in 2014.
The physical-layer specifications of the Ethernet family of computer network standards are published by the Institute of Electrical and Electronics Engineers (IEEE), which defines the electrical or optical properties and the transfer speed of the physical connection between a device and the network or between network devices. It is complemented by the MAC layer and the logical link layer. An implementation of a specific physical layer is commonly referred to as PHY.
40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively. These technologies offer significantly higher speeds than 10 Gigabit Ethernet. The technology was first defined by the IEEE 802.3ba-2010 standard and later by the 802.3bg-2011, 802.3bj-2014, 802.3bm-2015, and 802.3cd-2018 standards. The first succeeding Terabit Ethernet specifications were approved in 2017.
A core router is a router designed to operate in the Internet backbone, or core, or in core networks of internet service providers. To fulfill this role, a router must be able to support multiple telecommunications interfaces of the highest speed in use in the core Internet and must be able to forward IP packets at full speed on all of them. It must also support the routing protocols being used in the core. A core router is distinct from an edge router: edge routers sit at the edge of a backbone network and connect to core routers.
DE-CIX is an operator of carrier- and data-center-neutral Internet Exchanges, with operations in Europe, North America, Africa, the Middle East, India and Southeast Asia. All DE-CIX activities and companies are brought together under the umbrella of the DE-CIX Group AG.
The Atlanta Internet Exchange (AtlantaIX) is an Internet Exchange Point situated in Atlanta, Georgia, United States. AtlantaIX is a fast-growing, neutral and independent peering point. The beginnings of the AtlantaIX can be traced back to 1997. The current version of the AtlantaIX was re-established on September 4, 2003 by Michael Lucking, GreatAccess.com, WV Fiber and 56 Marietta Street Partners. AtlantaIX was originally created as a free exchange point sponsored by the donations of the founders. Today AtlantaIX continues to run without any re-occurring charges to the participants. In 2007, one time port fees were instituted to aid in paying for a recently upgraded switch infrastructure. In January 2007, Michael Lucking purchased a new Foundry Networks Jetcore 15000 in order to support 10 Gigabit Ethernet connections. In January 2008 the switch fabric was migrated to a Cisco 6509 in order to support line rate 10 gigabit Ethernet. In early 2008, the AtlantaIX began supporting IPv6.
Dell Force10, was a United States company that developed and marketed 10 Gigabit and 40 Gigabit Ethernet switches for computer networking to corporate, educational, and governmental customers. It had offices in North America, Europe, and the Asia Pacific region.
In Romania, there are 18.8 million connections to the Internet. Romania's country code is .ro. The .eu domain is also used, as it is shared with other European Union member states. There were over 600 000 domains registered under .ro at the end of 2012.
Carrier Ethernet is a marketing term for extensions to Ethernet for communications service providers that utilize Ethernet technology in their networks.
10 Gigabit Ethernet is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second. It was first defined by the IEEE 802.3ae-2002 standard. Unlike previous Ethernet standards, 10GbE defines only full-duplex point-to-point links which are generally connected by network switches; shared-medium CSMA/CD operation has not been carried over from the previous generations of Ethernet standards so half-duplex operation and repeater hubs do not exist in 10GbE. The first standard for faster 100 Gigabit Ethernet links was approved in 2010.
Thunderbolt is the brand name of a hardware interface for the connection of external peripherals to a computer. It was developed by Intel in collaboration with Apple. It was initially marketed under the name Light Peak, and first sold as part of an end-user product on 24 February 2011.
Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet and 200 Gigabit Ethernet standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet was approved on December 6, 2017. On February 16, 2024 the 800 Gigabit Ethernet standard developed by the IEEE P802.3df Task Force was approved.
10G-PON is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s over dark fiber. This is the ITU-T's next-generation standard following on from GPON or gigabit-capable PON. Optical fibre is shared by many subscribers in a network known as FTTx in a way that centralises most of the telecommunications equipment, often displacing copper phone lines that connect premises to the phone exchange. Passive optical network (PON) architecture has become a cost-effective way to meet performance demands in access networks, and sometimes also in large optical local networks for fibre-to-the-desk.
Ethernet over fiber is a networking technology that delivers Ethernet bandwidth ranging up to 400 Gbit/s using optical fiber lines. Such wired transmission methods extend connectivity over long distances up to 200 km, support higher bitrates and provide far greater immunity from electromagnetic interference (EMI) than electrical connections. Copper-based Ethernet connections are generally limited to a maximum length of 100 meters or less, a maximum speed of 40 Gbit/s, and they are more easily affected by surrounding EMI.
