In 2020, we started planning a new topology of the NIX.CZ infrastructure from a virtualized star to a leaf-spine topology using Virtual Extensible LAN. This change ensures higher stability of the entire peering platform and, last but not least, simplifies further development. Thanks to the topology modified in this way, we were able to connect other locations - Bratislava and Vienna, and distribute data flows optimally. The technology change allowed us to efficiently handle the continued increase in the volume of data transferred.

Due to the high demand for 100GE connections and the growing demand for 400GE connections in 2020, NIX.CZ started deploying Cisco Nexus 9300 access switches.
