UKCES Technical Architecture document

Introduction
The UK Commission for Employment and Skills (UKCES) has two physical building
locations:

Renaissance House – Wath upon Dearne
28 – 30 Grosvenor Gardens – London – soon to be moving to Sanctuary Buildings, London.

Staff are located at each site, with an official split of 69 in Wath, 30 in London.

Wath and London are connected via a Data Centre in the North East of England via a
National Ethernet circuit (100mb). Cisco 3800 series routers sit at either end of the circuit
with the internal networks at both sites then being governed by Cisco ASA 5500 series
firewalls. An additional site to site 100mb link is in the process of being commissioned but for
now, both sites go via the Data Centre.

London staff have their own dedicated Domain Controller for network authentication and File
and Print Server for personal drive access. Additionally, there is a Microsoft Exchange 2003
server for all London staff. There is also a dedicated Cisco Call manager server for
telephone calls but the remainder of systems are located at Wath and accessed (by London
staff) over the 100mb link.
Telephone calls at both sites go out to the PSTN via a Cisco 2800 series router connected to
an ISDN 30 circuit. Both sites have a dedicated circuit for their external phone calls. Inter-
site calls come across the 100mb National Ethernet circuit.
Both sites have 10mb of internet browsing at the end of the 100mb National Ethernet, via the
Data Centre.

UKCES also host some servers and systems at the Data Centre. These systems are public
facing but can be accessed from the UKCES internal LAN on specific IP address controlled
machines. The hosted servers are in a DMZ. There is also a non-DMZ area which is an
extension of the internal UKCES LAN.
