ACOnet (Austrian Academic Computer Network) is the Austrian NREN (National Research and Education Network). Its goal is to provide services to (primarily) non-profit institutions in the realms of science, research, education, art and culture. ACOnet offers its participants a high-performance network infrastructure covering all of Austria with excellent international connectivity, as well as a wide range of services.  Mission & Purpose

Currently, there are around 300 ACOnet participants all over Austria - including Austria’s universities and universities of applied sciences, the Austrian Academy of Sciences, research and educational institutions, dormitories, libraries, art and cultural institutions, as well as public administration and health care institutions.  List of Participants

Participation in ACOnet also includes access to a wide range of services, such as TLS/SSL certificates, eduroam, ACOnet CERT, ACOnet Identity Federation, name services, and many others. For details please see Services & Tools.

• fail-safe national fiber-optic backbone (100 Gbps technology) with global IPv4 and IPv6 connectivity
• scientific and local data traffic, as well as any uploads, are free of charge and unlimited
• generously sized, flat-rate premium Internet service with DDoS protection, extensive peering at the Vienna Internet eXchange, and up to 16 times the subscribed bandwidth during peak periods
• support for individual or collaborative participant projects
• permanent VPN connections between locations and closed user groups (e.g., GovIX) are possible

The requirements for participation in ACOnet are listed in the German-language documents "Grundsaetze fuer die Teilnahme an ACOnet" und "ACOnet Acceptable Use Policy".  Download

To become an ACOnet participant, please read the German-language documents "Grundsaetze fuer die Teilnahme an ACOnet" and "ACOnet Acceptable Use Policy". Afterwards, please fill in the form "Vereinbarung betreffend die Teilnahme an ACOnet" and send it to ACOnet.  Details & Documents

In cooperation with participating organizations and partners, ACOnet operates Points of Presence (PoPs) at 22 locations throughout Austria. A diagram of the ACOnet backbone showing the ACOnet PoPs can be found under Topology.

Yes. The Federal Ministry of Women, Science and Research is funding ACOnet connections for Austrian dormitories. For this purpose, the agency running the dormitory needs to apply for an ACOnet connection including commercial internet bandwith under the title of "VCampus". The subsidized bandwidth depends on the number of students accomodations.  Details (German only)

The aim of the VCampus NightLine is to provide student dormitories connected to ACOnet with a better internet connection during nighttime hours and on weekends without additional ACOnet costs.  Details (German only)

Please see our List of Dormitories and their respective agencies.

Class of Service (CoS) is a method to mark data packets depending on their origin. For data packets coming from commodity sources, the limitation to the subscribed bandwidth applies (with up to 1600 % burst capacity). In contrast, data packets originating from other ACOnet participants or from other NRENs (National Research and Education Networks) via GÉANT are marked as scientific. For these packets, bandwidth is not limited by ACOnet, but solely by the capacity of the "last-mile" connection to the participant.  Details
