A discounter needs to keep its costs to a minimum and ensure streamlined, fast processes. This means that chain stores need to be controlled, managed and, of course, supplied from a central location. The solution provided here involves an IT infrastructure which securely connects all network users with each other at minimal expense. Netto as a brand discounter uses a Virtual Private Network (VPN) for this connection. In total, 1,200 routers of the type ADSL 1200 II were installed in the individual Netto markets and are operated behind the ADSL modem of a DSL provider. The network solution connects each chain store to the head office and transmits information such as order data, accounting data and EC card information requests quickly and securely. The entire implementation period lasted less than nine months. The system grows with the heavily expanding company: each year, Netto opens some 150 new stores, which can easily be linked to the system without additional cost involved.
