State of Schleswig-Holstein: A network for all services

In the past, there were five independent communications networks in Schleswig-Holstein. The state wanted to combine these to form a single network, the Schleswig-Holstein communications network. Its performance and functions should far exceed those of the old networks. The specifications included not only data communications but also the integration of voice communication via Voice over IP (VoIP) for example.

MPLS technology guarantees high connection quality between all sites

T-Systems came up with a solution based on MPLS technology (Multi-Protocol Label Switching) for the federal state. MPLS allows for example VPNs (virtual private networks) to be set up flexibly with quality of service. This means that various priorities can be assigned to the transmission forms such as voice or data. The data with the highest category always have priority within the network. T-Systems has connected all IT systems and telephone systems at the individual sites to the MPLS backbone via access routers and VoIP gateways. The redundant design guarantees an availability of 99.8 percent. A special “service area” operated by the state’s own data center makes it possible to monitor the network and adapt it to individual requirements. For example, the transition between two VPNs is only possible in the service area and is therefore completely under the control of the operator. The solution from T-Systems connects over 80 state authorities to around 40,000 employees at 320 offices all over the state. There are plans to expand it to over 500 offices.

Details regarding the state of Schleswig-Holstein reference

  • Covering an area of 15,764 km2 and with just under 2,780,000 inhabitants, Schleswig-Holstein is sparsely populated.
  • Providing services for residents and organizational structures throughout the state is therefore no easy task for the state government.
  • The Interior Ministry in particular depends on a high-performance communications infrastructure given its wide range of different tasks.
  • It is responsible for the police and for protection of the constitution and is also the highest construction supervisory body in the state.
  • Bringing together five independent communications networks in one network for voice and data.
  • Integrating voice communication via Voice over IP (VoIP) at 700 sites.
  • Assigning “qualities of service” for data and voice traffic.
  • Authorities and sites should be able to form closed user groups on the basis of VPNs (virtual private networks).
  • Connecting over 80 state authorities with 320 offices and 40,000 employees in an MPLS voice and data network.
  • Broadband connection of all IT systems and telephone systems to the MPLS backbone via access routers and VoIP gateways.
  • MPLS technology directly supports VoIP and VPN development.
  • The redundant network design guarantees an availability of 99.8 percent.
  • Data protection conformity and audit compliance are integral features.
  • The state’s own data center can monitor and adapt the network itself.
  • Calls within the entire network are free.
  • Because calls are routed outwards to a telephone system in the destination network, only local call charges are incurred.
