+ | |||
+ | ===== Local Area Networking ===== | ||
+ | |||
+ | |||
+ | |||
+ | The campus LAN is Ethernet-based, | ||
+ | |||
+ | Fibre optics forms the main core of the backbone cabling infrastructure, | ||
+ | |||
+ | |||
+ | ===== Campus Network Development ===== | ||
+ | |||
+ | |||
+ | The campus network is expanding all the time. Many departments are installing additional network cabling, or upgrading their existing ones, and more network switches are to be installed. There are also plans to wire up individual student rooms in Halls of Residence. | ||
+ | |||
+ | All recently installed and upgraded departmental cabling would be of Category 5 twisted-pair type, capable of transmitting packets at 100 MBits per second (Mbps). To achieve this performance, | ||

+ | |||
+ | ===== Network Applications ===== | ||
+ | |||
+ | |||
+ | The campus LAN offers a range of standard services to end users, including access to electronic mail(email), | ||
+ | |||
+ | New users may find doucuments such as [[http:// | ||

+ | |||
+ | ===== WWW Caching ===== | ||
+ | |||
+ | Caching is becoming commonplace on the World Wide Web. Copies of web pages and related objects are stored for repeated references, instead of having to fetch them each time they are referred to. The advantage is to conserve network bandwidth and to improve response time. | ||
+ | |||
+ | With charging on transatlantic traffic introduced recently, caching is being seen as one way of managing WWW traffic. Caching can be done locally on end user computers, across campuses or nationally within JANET. Popular WWW browsers, such as Netscape and Internet Explorer, have caching facility built-in, which is easily configurable by users. | ||
+ | |||
+ | The University has a WWW cache server available to all users on campus (wwwcache.swan.ac.uk). There is also a backup server running which should automatically switch over if the main server fails. Both of the UWS servers are linked to two national cache servers within JANET, one is operated by the University of Manchester and the other by the Loughborough University. | ||

+ | |||
+ | ===== Wide Area Networking ===== | ||
+ | |||
+ | ==== Joint Academic Network (Super JANET) ==== | ||
+ | |||
+ | SuperJANET is a project within the Joint Academic Network (JANET) to replace the backbone network with a high quality and high speed network, which will take the UK academic and research community into the next millennium. | ||
+ | |||
+ | The final phase of the SuperJANET project (SuperJANET III) has recently been completed. A 34 Mbps ATM circuit is connecting the South Wales MAN to JANET and two 45 Mbps circuits connecting JANET to North America. | ||
+ | |||
+ | Charging on transatlanic network traffic has just been introduced to fund this extra bandwidth to North America. | ||
+ | |||
+ | |||
+ | ==== South Wales Metropolitan Area (MAN) ==== | ||
+ | |||
+ | |||
+ | The South Wales MAN (Metropolitan Area Network) is one of the many regional networks within JANET and the first broadband network in Wales. It is operated by the South Wales MAN consortium whose members include: | ||
+ | * University of Wales Swansea | ||
+ | * University of Wales Cardiff | ||
+ | * University of Wales College of Newport | ||
+ | * University of Wales College of Medicine | ||
+ | * University of Wales Institute Cardiff | ||
+ | * University of Glamorgan | ||
+ | * Swansea Institute of Higher Education | ||
+ | |||
+ | Member institutions communicate with each other via a 155 Mbps ATM circuit. | ||
