The migration of Tesco's existing network and systems on to a single virtual private network (VPN) will enable employees to access and share information and applications on the shop floor, boosting customer service levels, said Philip Clarke, IT and logistics director at Tesco.
"This move provides us with a framework through which IT for our stores can be delivered," he said. "By giving our colleagues access to better systems and up-to-date information we can enable them to deliver great service for customers."
The IP-VPN is based on multi protocol label switching which is designed to allow the prioritisation of network traffic so that business-critical applications may be given priority over other, less urgent, data traffic.
The network will be scalable, so that new stores can easily be connected to it without complicated revisions and network changes, Energis said.
The deal will provide a welcome boost for IT staff at Energis. The telecoms provider has been hit hard by the economic slowdown and was bought out for only £150m by a financial consortium earlier this month.
