Scott Ferguson, IT services manager with Nextgen parent company Leightons Contractors is using the service because it enables greater 'customer control' over the network rather than 'carrier control'.

"We wanted end to end management of the existing VPN and wanted to shake the controls of signing with an IP VPN carrier," Ferguson said.

"The multiple VLAN and QoS features solved the problems on both implementing and managing IP telephony and also delivers wireless in a secure manner around the network.

"The transition was easy as we mirrored the existing IP VPN infrastructure and then introduced multiple VLANs and interconnected the changes."

Ferguson said VPLS stood out from other IP VPN offerings in the market.
