Infrastructure – basis for providing services

Reliable and high-capacity infrastructure is the basis for the successful provision of services.

These include network nodes, connections between nodes, international connections and connections to other providers in Slovenia, as well as the secure and reliable systems premises needed for the installation of servers and other active equipment.

More about Backbone network.

In 2023, Arnes completed the project ” Digitalisation for Open Science – Establishing the Backbone Network”, which, by upgrading the ARNES fibre backbone, is making a significant contribution to the development of a modern, accessible and competitive research and education environment that can underpin the advancement of science as well as the networking between research institutions. Alongside organisations in the fields of education, culture and other eligible organisations, all Slovenian public research organisations are connected through new links.

The upgrade of the ARNES fibre backbone for public organisations has made an outstanding contribution in the form of even more stable operation of long-distance fibre links, higher levels of operational reliability and, now with dual-fibre links, an excellent basis for the establishment of new, significantly faster connections between ARNES nodes at speeds from 100 Gb/s to 400 Gb/s and readiness for new technologies at speeds up to 800 Gb/s. The NOO funding has been used to establish 40 new long-distance links between ARNES nodes, implemented with different fibre providers. All nodes are now connected in fibre loops and their operation is significantly more resilient to possible interruptions of individual long-distance links.

The project has been included in the Recovery and Resilience Plan (RRP) co-funded by the European Union – NextGenerationEU and the Ministry of Higher Education, Science and Innovation in the framework of the Union’s response to the COVID-19 pandemic.
