Network topology


Our new NIX.CZ leaf-spine infrastructure topology, built on Virtual Extensible LAN (VxLAN) and Ethernet Virtual Private Network (EVPN), brings a revolutionary improvement to the stability and development of our peering platform. This combination of modern technologies enables efficient connection and management of data flows in our network.

By using VxLAN, we have achieved greater flexibility and scalability in our network. This technology enables the creation of virtualized network segments, which gives us the ability to dynamically connect sites and optimize data flows. Thanks to EVPN, we are able to efficiently manage routing and transfer information about network paths between devices.

The new topology enabled a transition from the original virtualized star to a leaf-spine model, creating redundancy and increasing overall network reliability. In this way, we could easily integrate other locations, including Bratislava, Vienna and Frankfurt, and optimize the data flow between them.

In 2020, in response to the growing demand for high-speed connections, we started deploying Cisco Nexus 9300 access switches. These switches allow us to provide 100GE and even 400GE connections, which meets the ever-increasing data transfer demands of our network. In this way, we were able to effectively manage the continued increase in the volume of transferred data and provide our customers with top-notch and scalable access to our peering platform.
