Janet is a high-speed network for the UK research and education community provided by Jisc, a not-for-profit company set up to provide computing support for education. It serves 18 million users and is the busiest National Research and Education Network in Europe by volume of data carried. Previously, Janet was a private, UK-government funded organisation, which provided the JANET computer network and related collaborative services to UK research and education.
A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic region of the size of a metropolitan area. The term MAN is applied to the interconnection of local area networks (LANs) in a city into a single larger network which may then also offer efficient connection to a wide area network. The term is also used to describe the interconnection of several LANs in a metropolitan area through the use of point-to-point connections between them.
A digital subscriber line access multiplexer is a network device, often located in telephone exchanges, that connects multiple customer digital subscriber line (DSL) interfaces to a high-speed digital communications channel using multiplexing techniques. Its cable internet (DOCSIS) counterpart is the cable modem termination system.
A leased line is a private telecommunications circuit between two or more locations provided according to a commercial contract. It is sometimes also known as a private circuit, and as a data line in the UK. Typically, leased lines are used by businesses to connect geographically distant offices.
CARNET is the national research and education network of Croatia. It is funded from the government budget and it operates from offices in Zagreb and five other cities.
AARNet provides Internet services to the Australian education and research communities and their research partners.
A broadband remote access server routes traffic to and from broadband remote access devices such as digital subscriber line access multiplexers (DSLAM) on an Internet service provider's (ISP) network. BRAS can also be referred to as a broadband network gateway or border network gateway (BNG).
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.
A metropolitan-area Ethernet, Ethernet MAN, carrier Ethernet or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or for internet access. Businesses can also use metropolitan-area Ethernet to connect their own offices to each other.
Open Transport Network (OTN) is a flexible private communication network based on fiber optic technology, manufactured by OTN Systems.
In computer networking, an edge device is a device that provides an entry point into enterprise or service provider core networks. Examples include routers, routing switches, integrated access devices (IADs), multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices. Edge devices also provide connections into carrier and service provider networks. An edge device that connects a local area network to a high speed switch or backbone may be called an edge concentrator.
A computer network is a set of computers sharing resources located on or provided by network nodes. Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.
The very high-speed Backbone Network Service (vBNS) came on line in April 1995 as part of a National Science Foundation (NSF) sponsored project to provide high-speed interconnection between NSF-sponsored supercomputing centers and select access points in the United States. The network was engineered and operated by MCI Telecommunications under a cooperative agreement with the NSF.
SURF is an organization that develops, implements and maintains the national research and education network (NREN) of the Netherlands. It operates the national research network formally called SURFnet.
CANARIE is the not-for-profit organisation which operates the national backbone network of Canada's national research and education network (NREN). The organisation receives the majority of its funding from the Government of Canada. It supports the development of research software tools; provides cloud resources for startups and small businesses; provides access and identity management services; and supports the development of policies, infrastructure and tools for research data management.
Delivery of Advanced Network Technology to Europe (DANTE) is a not-for-profit company that plans, builds and operates the consecutive generations of the backbone network that interconnects the national research and education networks (NRENs) in Europe. The organisation is based in Cambridge, United Kingdom and was formed in 1993 as a limited liability company owned by Réseaux Associés pour la Recherche Européenne (RARE). Ownership was transferred to a number of NRENs and government agencies in 1994.
Iceland is among the top countries in the world in terms of Internet deployment and use. 99.68% of Icelanders used in the internet in 2021.
The Research and Educational Networking Association of Moldova (RENAM) is the national research and education networking organisation (NREN) of Moldova. RENAM was incorporated in June 1999 as an association under Moldovan law. It is a member of TERENA.
SANET is the national research and education networking organisation of Slovakia. The SANET association is a non-profit organisation whose members contribute to the operations of the network. It is a member of TERENA.
ACOnet is the name of the national research and education network in Austria. The ACONET association promotes the development and use of that network. ACOnet is not managed and operated by ACONET, but by a unit in the Computing Centre of the University of Vienna that also operates the Vienna Internet Exchange. The University of Vienna represents ACOnet internationally, for example as a member of TERENA and as a participant in the project that funds the European backbone network GÉANT.
