SuperJanet         
An initiative started in 1989, under the Computer Board, with the aim of developing of a national broadband network to support UK higher education and research. The preparatory work culminated in 1992 with the award of a contract worth 18M pounds to British Telecom to provide networking services over a four year period that extends to March 1997. The BT contract will provide a national network with two components: a high speed, configurable bandwidth network serving up to 16 sites, initially using PDH to be replaced with SDH, and a high speed switched data service (SMDS) serving 50 or more sites. The primary role of the PDH/SDH component will be to support the development and deployment of an ATM network. These components will be complemented by several high performance Metropolitan Area Networks each serving several closely located sites. The aim is to provide, within the first year of the project, a pervasive network capable of supporting a large and diverse user community. The network has two parts, an IP data network and an ATM network, both operating at 34Mbit/s. Early in August 1993 the pilot IP network was transferred to full service and was configured to provide a trunk network for JIPS, the {JANET IP Service}. In November 1993 work was well advanced on the next phase which aims to extend SuperJANET to a large number of sites. The pilot four site ATM network will be extended to serve twelve sites and will expand the scope of the video network. The principal vehicle used for the expansion of the data network will be the SMDS service provided by BT. Most of the work associated with the development of this phase is expected to be completed by the end of March 1994.

UKERNA         
United Kingdom Education and Research Networking Association (Reference: org., UK)
Joint Academic NETwork         
(JANET) The wide area network which links UK academic and research institutes. JANET is controlled by the {Joint Network Team} (JNT) and Network Executive (NE). It is an internet (a large number of interconnected sub-networks) that provides connectivity within the community as well as access to external services and other communities. The hub is the JANET subnetwork, a private X.25 packet-switched network that interconnects over 100 sites. At the majority of sites, local area networks (LANs) are connected to JANET allowing off-site access for the computers and terminals connected to these networks. The Coloured Book protocol architecture is used to support interactive terminal access to computers (for both character terminals and screen terminals), inter-host file transfers, electronic mail and remote batch job submission. http://nic.ja.net/.

JANET

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.

All further- and higher-education organisations in the UK are connected to the Janet network, as are all the Research Councils; the majority of these sites are connected via 20 metropolitan area networks across the UK (though Janet refers to these as regions, emphasising that Janet connections are not just confined to a metropolitan area). The network also carries traffic between schools within the UK, although many of the schools' networks maintain their own general Internet connectivity. The name was originally a contraction of Joint Academic NETwork but it is now known as Janet in its own right.

The network is linked to other European and worldwide NRENs through GÉANT and peers extensively with other ISPs at Internet Exchange Points in the UK. Any other networks are reached via transit services from commercial ISPs using Janet's Peering Policy.

The Janet network is operated by Jisc Services Limited, part of Jisc. Janet is also responsible for the .ac.uk and .gov.uk domains. On 1 December 2012, Janet and Jisc Collections joined together to form Jisc Collections and Janet Limited, as subsidiary organisations to Jisc. In March 2015, Jisc Collections and Janet Limited was renamed to Jisc Services Limited. Jisc Services continues to operate under the brand name of Janet, with the same remit. Janet was previously known as the JNT Association, and prior to that, UKERNA (the United Kingdom Education and Research Networking Association).
