IndustriesAll

Challenge

Compliance with legal and regulatory requirements while ensuring technical and organizational interoperability

Solution

BSI- and TKG-compliant network deployment and operation by Conneqtive, a provider registered with the Federal Network Agency (BNetzA)

Highlights

  • Carrier-class availability in the backbone
  • Resistance to blackouts
  • GDPR compliance
  • KRITIS- and defense-resilient data transmission

Starting Point

Before CHEMPARK was formed, Bayer’s in-house IT operated a network that grew organically within the corporation. But the spin-offs of Covestro, CURRENTA, Lanxess, and 70+ new companies setting up their operations, the physical division of real estate and networks became mandatory. The internal Bayer IT could no longer guarantee capacity, availability, security, and data protection for so many external parties.

Challenged problems

  • No security at the CHEMPARK sites
    The security of networks and services could no longer be guaranteed in accordance with § 164 et seq. of the Telecommunications Act (TKG).
  • Lack of capacity and availability
    When Bayer's internal IT operations were outsourced, the operator was lost.
  • Outdated infrastructure
    The infrastructure, which had evolved over time, no longer met the latest technical standards for structured campus cabling in accordance with EN 50173.

Solution

Conneqtive was founded as a CHEMPARK provider

  • Redundant backbone across the CHEMPARK sites
  • Peering connections in Düsseldorf and Frankfurt to DE-CIX
  • Fully redundant data center locations at each CHEMPARK site, serving as central hubs
  • disconnected connection of 650 buildings
  • Deployment of new fiber-optic networks
  • disruptive replacement of static point-to-point-to-point connections with dynamic point-to-multipoint architectures ​

Outcome

  • Compliance with the requirements of the Telecommunications Act (TKG)
  • 1,100 km of fiber-optic cable along a 60 km secure cable route
  • 650 building connections, 700 active components
  • over 1,000 managed service connections
  • Introduction of SLAs and Availability
