With the data Centre situated in the main building in Keppel Street, the Data Centre Ethernet
switch provides external links to the School's Gower Street premises three-quarters of a mile
away via a 10-Mbit/sec microwave circuit. There is also a laser-link connection to another
nearer site capable of 100-Mbit/sec, but currently running at 10-Mbit/sec.
The main Keppel Street building also provides 10-Mbit/sec fibre optic connections to:
- An FDDI-based metropolitan area network (MAN)
- A second building in Taverton Street
- SuperJanet, the UK-wide universities network
Additionally, Cable London provides a 2-Mbit/sec cable for voice and backup data services
between Data Centre and Taverton Street. ISDN service provides communication for off-site
personnel. A full application dial-up service running under Windows NT is also provided,
with full internet access.
SunNet Manager provides SNMP error code detection and reporting.
Physical and Logical network management
The KONFIG® network management system, which uses the ORACLE relational database and
interfaces to SunNet manager, is designed to provide the School with both logical and physical
network management facilities and a graphical window into the network database.
KONFIG® displays the physical network infrastructure - including devices, equipment,
cabling, and ID references - over the building floor plan in 2D or 3D. KONFIG® automatically
shows the network support staff precisely where everything is located.
When faults are detected, KONFIG®'s interface to SunNet Manager can graphically display
affected devices in their physical locations, and can also provide a fault report. Because
KONFIG® manages all network connectivity, it can also display affected cable runs and other
Alternatively, a network manager can click on any device or cable run on the displayed
floor plan and have KONFIG® generate a database report on the selected item.
