Kingston Communications has won a "substantial" contract to replace the Food Standards Agency's local area networks (Lans) across the UK.
The deal was awarded to the Hull-based communications firm by managed service provider Atkins Management Consultants.
Kingston will redesign the food watchdog's existing legacy Lans that support 1,000 users at five UK sites, and replace them with a modular infrastructure based on Cisco Catalyst switches.
Kingston will also maintain the Lans, in conjunction with Atkins, and will supply Cisco's Works for Windows network management system.
This will allow Atkins to identify faults and improve capacity planning.
Under the terms of the deal, Kingston will also replace and support the Lans at sites belonging to York-based Meat Hygiene Service, an executive agency of the Food Standards Agency.
"Our food safety role means that a highly resilient infrastructure is vital," said Philip Cross, information systems manager at the Food Standards Agency.
"In the event of a major food incident, we need to be able to respond quickly and we need efficient disaster recovery systems.
"Our aim was to build in a level of resilience which would ensure that the agency was not susceptible to the failure of any individual element of the Lans."
