Network modernisation at a multi-building site

Jonas Jakob · 17 March 2025

Switch with connected patch cables and yellow cable labels

JITIS rebuilt the network for a site with several buildings used for different purposes. Administration and new work areas are served by a shared, segmented infrastructure.

Network technology implemented

  • 2.5 GbE at every network connection
  • Layer 3 switching for network segmentation
  • 10 GbE backbone between the distribution cabinets
  • Hybrid server solution for on-premises and cloud-based applications

A firewall with SSL inspection checks incoming and outgoing traffic for malicious websites and links.

A basis for further expansion

The network cabling was installed during renovation work so that the network can be extended later. The solution provides the basis for:

  • Wi-Fi in all areas in use
  • on-premises and cloud infrastructure working together
