SuperJANET forms part of the UK's higher education and research networking programme funded principally by the Higher Education Funding Councils of England, Scotland and Wales via their Joint Information Systems Committee (JISC).

SuperJANET is a national high performance network supporting UK education andresearch. It currently provides three services: a high performance IP service to all connected sites, an ATM service to a sub-set of the connected sites and a video network to the ATM sites. Access to the IP and ATM services is at 34 Mbps; developments are in progress to upgrade the ATM network to 155 Mbps. The network uses SMDS and PDH/SDH network services provided by BT, supplemented by other facilities such as 34 Mbps leased lines and dark fibre links. SuperJANET is connected to the European PNO ATM Pilot.

SuperJANET's primary role is to provide stable, high quality network services to meet the requirements of the UK university and research community. In addition, it is able to support network research and development activities to the extent that those activities are compatible with, and do not disrupt, the service provision to the wider user community. All use will be governed by the JANET and SuperJANET Acceptable Use Policy.

Technical information

Users gain access to the IP service via the local-area network (LAN) (e.g. Ethernet or FDDI) that serves the user's site. The LAN is connected to SuperJANET via a router with a high performance interface, the type of interface required depends on the type of SuperJANET access selected (e.g. SMDS, PDH link or dark fibre).

Access to the SuperJANET ATM network is via equipment on the user's site (e.g. an ATM switch or host computer) equipped with an ATM interface that is linked to the appropriate SuperJANET ATM switch. The type of interface required depends on the type of access selected (e.g. PDH or SDH link, dark fibre).

Access to the video network is via a video codec on the users site linked to the appropriate SuperJANET video switch via a 2 Mbps channel provided as a leased line or via the ATM network.

UKERNA will advise on the most suitable type of connection and the equipment required for that connection.

User community

SuperJANET has a large and growing user community. 60 institutions are currently connected of which 57 are universities and 2 are major national research laboratories. The network provides access to four national supercomputer centres and several other national research facilities.

A major expansion programme has recently been launched which is expected to increase the total number of organisations connected to more than 110 over the next three years, including all UK universities. It is expected that a growing number of organisations outside the university sector will connect to the network over the same period.

Based on initiatives from the Universities of Newcastle and Northumbria the Northern Informatics Applications Agency (NIAA) has been created to become the focus for telematics developments that will give the Northern Region of the UK a leading competitive advantage both nationally and internationally in the application of broadband communications and information services.

By stimulating and co-ordinating the creation of a Regional data network which is also a testbed for developing and piloting services and applications, the NIAA is providing an open forum in which suppliers and customers can co-operate for mutual advantage.

One of the primary objectives of the initiative is to co-ordinate the integration of a region-wide communications infrastructure as well as an associated programme of applications. This is being achieved by the integration of existing regional and national networks together with selective in-filling of the gaps. For example, the SuperJANET network is providing a core network of broadband-width services and is being interfaced with networks from utilities, Tecs and Business Links. Other large businesses in the region are also offering to integrate their communications networks into the regional infrastructure.

The objective is not only to provide excellent regional facilities but to make the region a key node on the world wide network.

User Community

The Northern Region covered by the NIM comprises the area of the five counties of Cleveland, Cumbria, Durham, Northumberland and Tyne and Wear. Costs

INTREPID (The IBC Network Trans-European Pilot Interoperability Demonstrator)

A RACE funded project, INTREPID, aims to provide a broadband infrastructure connecting users in two objective one regions of Europe, addressing issues with respect to interoperability and Quality of Service, and expanding the trials and user community across the network.

The INTREPID consortium comprises MARI (Northern Ireland) Limited, University College Dublin, the University of Ulster at Jordanstown and Mentec Picturecom Ltd. The trials are currently in the areas of tourism, educational teleworking and education multimedia database access tools.

Description of facility

INTREPID operates at the national and international level, linking networking facilities at the local level to the BT SMDS and the Dublin Metropolitan Area Network.

In Northern Ireland this will be done by connecting to the UK academic network SuperJANET or directly to BT SMDS, and thus connecting through to the ATM node in London. In Ireland the Metropolitan area network will be connected to the Telecom Eireann ATM Node.

Connectivity to the ATM pilot will provide opportunities to interwork with other broad band islands in Europe and carry out interoperability experiments across INTREPID.

Access to the service will be either via SuperJANET or via a direct connection to BT SMDS (UK) or the Dublin Metropolitan Area Network (Ire).

Digital broadcasting facilities

The BBC is the national public service broadcaster in the UK. It operates two national television networks and five national radio networks. It not only makes and schedules programmes, but also runs a network of point-to-point contribution links and broadcasting transmitters. Through its Research and Development Department the BBC keeps in the forefront of technology.

The BBC is collaborating with other broadcasters in Europe to look at the possibility of digital audio broadcasting (DAB) by satellite. It is considering starting a pilot digital terrestrial broadcasting service in London towards the end of 1995, with a view to offering a public service in 1997. A limited satellite DAB service is expected to be provided in mid-1995 using an Inmarsat satellite.

Optical fibre transmission

The BBC expects to be able to offer access to digital highways or unequipped optical fibres between some of its studio centres in London and elsewhere in the UK forming parts of its contribution and primary distribution networks. Digital highways will use the synchronous digital hierarchy (SDH) of ITU Recommendations G.707, 708, 709 operating at the STM-16 rate of 2.48 Gbit/s on single-mode optical fibre.

R&D TV and HDTV production facilities

The BBC R&D Department at Kingswood Warren (30 km south of the centre of London) has a small studio and recording suite equipped for TV and HDTV production and post-production. These facilities are suitable for the production of short test sequences and demonstrations.

The TV studio is equipped with 1250-line HDTV cameras and 625-line cameras, lighting and some scenery. 625-line and HDTV signals can be recorded on professional quality digital recorders. Post-production facilities include editing and captioning. Programme output is normally on tape, but satellite links can sometimes be set up with advance notice for live events.
