DFN-Verein co-operates very closely with several European organizations. The ultimate aim is an efficient and effective collaboration of the communications services both on a national and an international level. The activities of the national research and education networks are supported by two European organizations:

Dante
DANTE (Delivery of Advanced Network Technologies to Europe) based in Cambridge, UK, was established by national research and education networks, amongst others also DFN- Verein.
DANTE's most important task is to organize provision and operation of a communications infrastructure for the national research and education networks in Europe.

Terena
TERENA (Trans-European Research and Education Network Association) organizes the co-operation between national research and education networks in the areas of development, testing and promotion of new technologies, particularly applications and middleware. This co-operation is further promoted by conferences, workshops and seminars.
