The company anticipates savings of £1m on its network operating costs over the five-year term of the Vanco contract.
Kelly Services has grown through acquisitions in Europe, the Middle East and Africa, inheriting a range of network technologies. This has resulted in the company using a mixture of Frame Relay-based leased lines, ISDN, and IPSec virtual private networks running on ADSL.
This disparate infrastructure will be replaced with Vanco's MPLS (multi-protocol label switching) network, which uses a technology called MPLS Matrix to integrate multiple domestic MPLS provider networks.
MPLS is typically used to enhance an IP network. Routers on the incoming edge of the MPLS network add an "MPLS label" to the top of each packet, based on criteria such as destination IP address. This label is then used to steer a packet through the subsequent routers.
Vanco's MPLS network runs over ADSL and uses quality of service technology to label the packets.
Jason Jennings, European IT director at Kelly Services, said the company would be live on the new network in seven or eight countries by Christmas. The firm will run both old and new networks simultaneously, and migrate on a branch-by-branch basis.
The greatest challenge in migrating such a large operation is ensuring continuity of service. "We are spending as much time in the planning and migration as we can. Building a network from scratch is not particularly difficult. Migrating from one network to another is challenging," said Jennings.
By moving to a fully IP-based network, Jennings said Kelly Services would have the capability to run multiple VPNs and use voice over IP and video over IP in the future.
